murine MAb against human factor VIII, heavy chain
Description
The monoclonal antibody (clone ESH-5) is directed against human factor VIII:C. Mice were immunized with purified human factor VIII:C cryoprecipitate. Hybridomas were created by fusion of the immunized spleen cells with NS-1 murine myeloma cell lines.
Properties
The antibody (subclass IgG1) is directed against the A1 domain of intact heavy chain (functional epitope).
The cross-reactivity was tested via IRMA, in comparison with human plasma (100%): the antibody does not cross react with Pig, Dog, Baboon, and Cat, the antibody does cross-react with Rabbit (212%) and Guinea Pig (204%).
Presentation
Screw capped vial containing 0.5 mg of purified antibody in 50 mM sodium phosphate, 50 mM trisodium citrate, 10% Maltose pH 5.8, 0.01 % ProClin. The IgG concentration is 1 mg/ml. Spin the vial briefly before opening.
Storage and Stability
Store the antibody at 2°-8°C. For long-term storage the antibody should be aliquoted and stored at –20°C or colder. It is recommended to avoid freeze-thaw cycles.
Applications
A. Immunopurification / Immunodepletion
The antibody binds factor VIII:C from plasma when covalently coupled to gels (1).
B. Inhibitor
Clot inhibition was tested by incubation for 2 hours at 37°C, and was 62% at 500 μg/mL (highest conc. tested).
The antibody is conformation dependent and is not useful for Western blotting.
