Welcome, fellow scientists. As many of you know, antibodies are an essential component in our tool belt. Naturally produced as part of our immune system’s response to infectious agents like viruses or bacteria, these proteins display an incredible ability to bind to their target – the antigens – with amazing precision. It’s this quality that has made them invaluable in research experiments and clinical applications. But today, we’re zooming in on one particular type of antibodies that’s making a significant difference in the research landscape – recombinant antibodies.
At NeoBiotechnologies, we understand the pains associated with finding the right antibodies for your research needs. Achieving accurate and reproducible results require antibodies that are both specific and reliable. And that’s precisely where recombinant antibodies come into play.
In a nutshell, recombinant antibodies offer key advantages such as consistency, high affinity, scalability and engineering capabilities. These make them ideal for a variety of applications, including Immunohistochemistry, Flow Cytometry, Western Blotting, and Immunofluorescence.
Our immune system is a complex network of cells and proteins designed to protect us from infections and diseases. It’s a fascinating world, and antibodies play a starring role in it.
Antibodies, also known as immunoglobulins (Igs), are proteins produced by our immune system’s lymphocytes. Imagine them as unique soldiers in our body. They are created in response to foreign invaders, known as antigens, which could be anything from bacteria to viruses.
The magic of antibodies lies in their specificity and affinity. They recognize and bind to antigens with such precision that it’s like fitting a key into a lock. This interaction is paramount in fighting infections and diseases, and it has also made antibodies indispensable tools in research and clinical applications.
Antibodies come in different flavors, each with its own strengths and weaknesses. Let’s take a look at the three main types:
Monoclonal Antibodies: These are identical antibodies that recognize the same antigen. They are produced by a single type of immune cell and offer high specificity. However, their production involves the use of live animals and hybridoma technology, which can be time-consuming and challenging.
Polyclonal Antibodies: These are a mix of antibodies that recognize different parts of the same antigen. They provide a more robust response but lack the specificity of monoclonal antibodies.
Recombinant Antibodies: Here’s where it gets exciting. Recombinant antibodies are a type of monoclonal antibody, but they are created in a lab using recombinant DNA technology. No need for live animals or cultivating any hybridomas. Instead, we insert specific genes into the cells’ existing DNA, creating antibodies that are not only specific and reproducible but also customizable. We can engineer them for increased stability, affinity, or other attributes, which makes them incredibly versatile.
At NeoBiotechnologies, we manufacture over 500 monospecific Rabbit Recombinant Monoclonal Antibodies. These are ideal for various research applications, including Immunohistochemistry, Flow Cytometry, Western Blotting, or Immunofluorescence.
In the following sections, we will dive deeper into the world of recombinant antibodies, their advantages, and their applications. Stay tuned!
Diving into the world of recombinant antibodies, it’s important to understand their genetic makeup, their production process, and the role of recombinant antigens.
Recombinant DNA antibodies, also known as recombinant antibodies (rAbs), are a type of monoclonal antibody (mAb). They are produced in vitro using recombinant DNA technology. What sets these antibodies apart is that they are generated using synthetic genes and antibody fragments. This means we don’t need to immunize an animal or cultivate any hybridomas, making the production process more efficient and ethical .
The production process of recombinant antibodies follows a similar workflow. It begins with determining the sequence of the desired product. This sequence is then refined and cloned into a vector, which is usually a bacterium like E. coli. This bacterium is then transformed, allowing it to express the protein of interest. The expressed protein can then be purified from the culture broth .
Recombinant antigens play a vital role in the production of recombinant antibodies. These antigens are artificially manufactured, often by transforming a bacterium with a vector expressing the protein of interest. The expressed protein, which is the recombinant antigen, can then be used to stimulate the production of specific antibodies. This offers a controlled, precise, and efficient way to produce antibodies with high specificity .
At NeoBiotechnologies, we pride ourselves on our rigorous production process and commitment to quality. Our team of scientists works tirelessly to develop, manufacture, and validate our recombinant antibodies. This ensures that you, as researchers, can trust our products for your groundbreaking work.
In the next section, we will explore the advantages of recombinant antibodies, and why they are becoming the preferred choice for many researchers. Stay tuned!
As we dive deeper into the world of recombinant antibodies, it becomes increasingly clear why they are gaining popularity in scientific research and clinical applications. There are four main advantages of recombinant antibodies that set them apart from traditional monoclonal or polyclonal antibodies: consistency and reproducibility, specificity and high affinity, scalability and speed of production, and engineering and optimization capabilities.
Recombinant antibodies exhibit a high level of consistency and reproducibility, making them an ideal choice for researchers who require reliable results. Since these antibodies are produced using defined DNA sequences, the results derived from their usage are consistent and replicable. This eliminates the lot-to-lot variability often seen with polyclonal antibodies, which can lead to inconsistent results and difficulties in reproducing experiments.
The specificity of recombinant antibodies is another major advantage. They can be engineered to bind with high affinity to a specific target, reducing the risk of non-specific binding. This high specificity and affinity make them suitable for a range of applications, including immunohistochemistry, flow cytometry, and western blotting.
The production of recombinant antibodies is not only faster than traditional methods but also scalable. Since they are produced in vitro, the process is more controllable and can be easily scaled up. This makes recombinant antibodies a cost-effective option for large-scale experiments and clinical applications. For instance, researchers were able to develop recombinant human Abs against the SARS-Cov-2 spike protein within just a few weeks.
One of the most exciting aspects of recombinant antibodies is the ability to engineer them for specific uses. They can be modified to improve their binding affinity, increase their stability, or change their immunogenicity. These antibodies can also be engineered as a carrier to help target drugs to specific cells or tissues, making them a promising tool in the development of new therapeutic strategies.
At NeoBiotechnologies, we leverage these advantages to manufacture over 500 highly validated, monospecific rabbit recombinant monoclonal antibodies. Our aim is to provide you with precision antibodies that work, ensuring your research is built on a foundation of reliability and consistency.

Recombinant antibodies have proven to be vital in the development of new therapies, including cancer treatment. Their small size allows them to penetrate tissues more easily, delivering highly specific drugs to precise locations in the body. Furthermore, their great specificity and the fact they’re not derived from hybridoma cell lines mean they don’t cause the infamous “human anti-mouse antibody” (HAMA) reaction, making them safer for therapeutic use.
Recombinant antibodies are also essential in disease detection. For example, they offer a promising alternative for diagnosing rabies, as they are more accurate and precise than current diagnostic antibodies. This accuracy is vital for diseases like rabies, where timely and accurate diagnosis is crucial for patient survival.
Moreover, the recombinant antibodies’ ability to potentially act as a neutralizing antibody as part of subsequent treatment further solidifies their importance in disease detection and treatment.
Recombinant antibodies are also used to explore protein-protein interactions, a critical aspect of understanding cellular functions and mechanisms of disease. Thanks to their high specificity, they can accurately identify and bind to single antigens, revealing detailed and precise information about these interactions.
In essence, recombinant antibodies are versatile tools that play vital roles in various fields.

The production of traditional hybridoma antibodies involves creating a hybrid cell line, which can be quite a lengthy and complex process. On the other hand, recombinant antibodies can be produced much faster and with better control over the process, making them a more efficient choice.
One of the most significant advantages of recombinant antibodies is their consistency and reproducibility. Unlike hybridomas, recombinant antibodies are not susceptible to contamination, genetic drift, or accidental loss. With a known sequence, recombinant antibodies can always be reproduced precisely for further use.
Recombinant antibodies also shine in terms of their design capabilities. They can be engineered to a virtually limitless extent against any antigen, of the proper size and shape, and are not solely limited to the peptide nature of an antigen. They can also be fused with drugs or toxins, providing enormous potential in medical applications.
Another important aspect is the EU Reference Laboratory for Alternatives to Animal Testing’s recommendation in favor of non-animal derived antibodies in May 2020. This was mainly based on the fact that recombinant antibodies, unlike animal derived antibodies, are always sequence-defined protein reagents. This allows for the elimination of some of the quality issues attributed to current research antibodies when made in animals.
At NeoBiotechnologies, we believe that recombinant antibodies do not necessarily have to replace traditional hybridoma antibodies, but rather complement them. With over 500 highly validated, monospecific Rabbit Recombinant Monoclonal Antibodies in our portfolio, we are dedicated to providing researchers with the most precise and reliable tools for their work.
The future of antibody production is likely to see a blend of both recombinant and hybridoma methods.
