Introduction
Together with Diagnostics, Leading Biology has extensive experience in producing monoclonal antibodies in hamsters. The use of hamsters as the host animal offers a unique species alternative in areas where mouse and rat antibodies may not work well. We can employ up to 10 hamsters for each antigen. Immune responses are elicited using immunogens such as transfected cell lines, DNA, recombinant proteins, native proteins, peptides or haptens conjugated to carrier molecules.
We perform splenocyte fusion on one or more animals. We select and subclone the strongly positive clones from the parental cultures by 2 rounds of limiting dilution cloning. Stable clones will be expanded into 24-well plates and then into T-flasks for further characterization. At no additional cost, clients could select one clone for in vitro production of approximately 1L of supernatant. Supernatants will be purified using Protein A/G column and pure antibodies will be deliverable. We also offer a full range of contract manufacturing services, including in vitro Antibody and Protein Production in bioreactors and large-scale Antibody Purification.
Our high affinity hamster antibodies are suitable for common research applications, including Chromatin Immunoprecipitation, ELISA, Fluorophore-linked immunosorbent assay, Immunocytochemistry, Immunofluorescence, Immunohistochemistry, Immunoprecipitation, and Western Blot.

Note:
1. Hamster source antibody and mouse source antibody have high similarity in their sequence, these similar sequences mostly concentrate on the Fc segment of antibodies, thus, to avoid the cross reaction with the mouse source antibody, hamster source antibody should use in combination with the secondary antibody which specifically recognize the hamster source antibody;
2. The specificity of hamster source antibody is better than mouse source, only after human source antibody;
3. Because the laboratory animals are relatively fragile, and the preparation process is complex, to prevent experimental accidents, the number of hamsters for the monoclonal antibody preparation project is at least five;
4. We use SPF level animals in the project, and Infectious antigen is strictly prohibited, the customers should acknowledge us if there are specific problems of the antigen, if the customers hiding their antigen information deliberately, and cause significant financial losses of the company, we will reserve the right to the legal responsibility;
5. The prices listed above are for reference only, the exact price needs to be decided according to the actual situation of the project.
Classic case
(Hamster monoclonal antibody service)
Customer Provide: Protein antigen\plasmid\protein information
Process
1. Antigen preparation\Plasmid expression\Protein purification\Peptide design, synthesis and conjugation.
2. Immunization of 2 Syrian hamsters.
3. ELISA/Western-blot test to monitor the antibody titer and specificity in hamster serum, according to ELISA and WB test result, screening hamsters.
4. Cell fusion
5. Positive screening: Using ELISA test to screening the antibody positive hybridoma clone.
6. Subclone: Using limited dilution to produce subclone from a positive clone, provide monoclonal supernatant to customers for tests.
7. Ascites preparation: Using mice celiac inoculation to produce the ascites of hybridoma products.
8. Antibody purification: Purify the secretory antibodies from 2 monoclonal hybridoma cell lines.
Products
