Hybridoma Production – Rat Hybridoma & Monoclonal Antibodies

 

Rats have some intrinsic characteristics covering that rats have better immune response than mouse under certain antigen stimulation, especially proteins derive from human beings, because of these proteins from human have a higher homology with mouse. In this case, rat is regarded as a suitable host for hybridoma/monoclonal antibody production and a tool for yielding higher specificity and affinity monoclonal antibodies. Meanwhile, rats have a higher capacity of 50-100 ml ascites of each rat compared with 3-5 ml ascites of each mouse which means scientists could harvest monoclonal antibodies from the rat hybridoma not only with a big amount but also with a batch consistency.

Alpha Lifetech Inc. has established a unique hybridoma platform to develop high-affinity monoclonal antibodies in rats. We use Winstar strain of rats as a resource of spleen cells and IR 983F myeloma as a chaperone cell to create high-expression and high-affinity monoclonal antibodies. Compared with commonly used mouse antibodies, rat antibodies do not have the background cross-reaction problems in immune-detection of antigens out of a mouse background, such as a mouse antigen from a mouse animal model. Another reason is that antibodies against mouse protein are difficult to be raised in mice themselves. Furthermore, we have created IR 983F cell line with lower expression of α-1, 6-fucosyltransferase by using RNAi technology, because IR 938F as chaperone cell possessing lower level of α-1, 6-fucosyltransferase that could efficiently reduce glycosylation of antibody (similar to function of YB2/0 myeloma cell line fused with B lymphocytes). Therefore, antibodies from other species have to be considered and rat monoclonal antibodies are a good choice for yielding low glycol modification antibodies.

Alpha Lifetech Inc. offers rabbit monoclonal antibodies

 In the realm of biotechnology and scientific research, obtaining high-quality antibodies is essential for accurate and reliable results. Alpha Lifetech Inc. has developed a groundbreaking monoclonal antibody technology specifically tailored for rabbit monoclonal antibody production.

Rabbit monoclonal antibodies have gained significant attention in recent years due to their unique characteristics and advantages over traditional mouse monoclonal antibodies.

 

The Key Benefits of Rabbit Monoclonal Antibodies:

 

Enhanced Sensitivity and Specificity: Rabbit monoclonal antibodies are known for their high specificity and sensitivity, enabling them to recognize and bind their target antigens with greater precision. This makes them particularly valuable in various applications, such as diagnostic tests and research purposes. 

Broadened Epitope Recognition: Rabbit immune systems generate a broader and more diverse range of antibodies compared to mice. This diversity allows rabbit monoclonal antibodies to recognize a wider variety of antigenic epitopes, including those that may be poorly immunogenic in mice.

Improved Stability and Affinity: Rabbit monoclonal antibodies typically exhibit better stability and affinity towards their target antigens than mouse-derived antibodies. This improved affinity and stability can lead to enhanced performance in various applications, including immunoassays, flow cytometry, and immunohistochemistry.

Faster Development and Production: Alpha Lifetech Inc.'s cutting-edge technology streamlines the process of rabbit monoclonal antibody production, enabling researchers to obtain high-quality monoclonal antibodies more quickly and efficiently.

Monoclonal Antibodies

    Monoclonal antibodies (mAbs) are immunoglobulins designed to target a specific epitope on an antigen. The antigen-binding region of the mAb is formed by the variable domains of the heavy and light chains and contains the complementarity-determining region that imparts high specificity for the target antigen. The monoclonal antibodies (mAb or moAb) recognize only one epitope per antigen and are less likely than polyclonal antibodies to react against other proteins. Monoclonal antibodies can be used to identify specific antigens. Due to their essential functions in various areas, monoclonal antibodies have become popular molecules.

    The first monoclonal antibody was generated in mice in 1975 by Milstein and Kohler using the hybridoma technique.

    The most popular approach for creating monoclonal antibodies is still hybridoma production. The hybridomas that produce monoclonal antibodies from the stable fusions to develop in vitro are chosen, sub-cloned, and formed. These clones are then cultivated, and either the cells themselves or the lysates from the cell culture are used to purify the antibodies they make. Each monoclonal antibody's specificity is determined by its binding site on the target protein.

Monoclonal antibodies (mAbs) production (Polyclonal and Monoclonal Antibody Production | Microbiology | | Course Hero)

    Alternative techniques for creating monoclonal antibodies have become available. The so-called "phage-display method" allowed for the specificity screening of recombinant antigen-binding antibodies from a library of fusions to a carrier phage protein. The constant region of recombinant antibodies may now be tailored due to significant advancements in their manufacture, leading to cell lines that can produce them. The benefit of this novel manufacturing approach is that it avoids the problems associated with a hybridoma's long-term stability, including the eventual loss of a priceless clone.

Advantages of Monoclonal Antibodies

(1) Batch to batch reproducibility

(2) The possibility of producing large amounts of identical antibodies

(3) Highly specific to a unique epitope

(4) Low cross-reactivity

(5) Most sensitive in tests where protein levels need to be quantified
