Mouse Monoclonal Antibody Production Service

KMD Bioscience has been working on producing monoclonal antibodies for many years. Mouse monoclonal antibody has many features such as targeting to a single epitope, high specificity, stable passage, large-scale manufacturing and extensive applications in basic research, medical diagnosis, tumor therapy. Our scientific staff has extensive monoclonal antibody development experience, with upgraded antibody technology, we can develop mouse monoclonal antibodies, which have advantages of high sensitivity and specificity.

KMD Bioscience is engaged in providing comprehensive services to meet customers’ different needs. We can provide two mouse monoclonal antibody production protocols: cell fusion technique, and phage display library construction technique. Meanwhile, we can provide antigen design, peptide synthesis, gene expression, immunization, antibody purification, identification and antibody labeling services with our well-established and powerful antibody engineering platform.

 

Mouse Monoclonal Antibody Production:

 

Production of mouse monoclonal antibodies by our hybridoma platform: Customers can provide small molecules, polypeptides, modified polypeptides, proteins, fusion proteins, modified proteins and the antigens for monoclonal antibody production. In the meanwhile, we also provide antigen customization services, including DNA synthesis, plasmid construction, protein expression, protein purification, protein modification, peptide synthesis, peptide modification, peptide and carrier protein cross-linking, small molecule structure analysis and carrier protein conjugation. Our lab staffs are expert in the development of in vitro diagnostic antibody & antigens, we have unique experience in the selection and identification of antibodies (such as in vitro detection of antigen immunogenicity).

Meanwhile, our patent adjuvant (FMA01# FastAb Mouse Adjuvant) can cause strong immune response after 21 days of immunization. In addition, we also provide a faster way-surgical spleen cell immunization to save investigator’s time.(FMA01# FastAb Mouse Adjuvant http://www.kmdbioscience.com/userfiles/1/files/nrgwy/pages/file/2020/07/FMA01%23%20FastAb%20Adjuvant.pdf)

Procedure

Description

Timeline

Immunization

1. Immunization of 5 mice (BALB/c), 3-4 times

2. Sera collection from 5 mice and ELISA titer determination

3. Immunization report will be delivered to investigator

4-6 weeks

Hybridoma Screening

1. Spleen cells (the highest serum titer) fused with mouse myeloma cells.

2.  Limiting dilution of fusion cells

3. HAT selection

4. Selection of 1-10 positive clones and subcloning to 96 plates

5. Screening positive subclones by ELISA and expansion of cultivation 

6. 1mL supernatant/positive clones delivered to investigator for testing

4-6 weeks

Production of Ascites Fluid (Optional)

1. The hybridoma cells selected by the investigator were used to produce ascites, mice were immunized, Protein A/G purified the ascites, and ELISA titer determination.

2.  Purified antibody is delivered to customer, <5mg/clone

3.  Provide detailed report and residual ascites antibody

1-3 weeks

Functional Verification (Optional)

ELISA, WB, IF, FLAC, IHC, etc.

1-3 weeks

 

 

Service Highlights:

 

--Rich experience in monoclonal antibody development
