IPKine heavy chain specific secondary antibodies-optimized for immunoprecipitation

Some researchers face a tough issueigg in immunoprecipitation (IP)or co-immunoprecipitation (co-IP): the primary antibody they use in IP or co-IP is the same as the one they have used in WB, or they raised from the same host. When this happens, the secondary antibody will recognize the primary antibody used in WB as well as the  denatured/reduced primary antibody released during the IP procedure . It directly result in two bands: the heavy chain (50kDa) and the light chain (25kDa).

If the size of your target protein is less than 30kDa, in order to avoid interference of the antibody light chain , we recommend using heavy chain specific secondary antibodies, such as :

Abbkine’s IPKine HRP AffiniPure Goat Anti-Mouse(Rabbit ) IgG Heavy Chain secondary antibody reacts with with Fc portion of mouse (rabbit) IgG heavy chain, and it doesn’t react with the Fab portion of mouse(rabbit) IgG. It's cross-reaction with bovine , horse and human serum proteins has been specialized minimized (anti-rabbit antibody only absorbed with human serum protein) , while it may cross-react with immunoglobulins from other species. It has no reactivity on non-immunoglobulin serum proteins. Furthermore, they are conjugated to horseradish peroxidase (HRP), ideal for western blotting.

Abbkine’s product line covers all kinds of antibody, biochemical, protein, assay kit, and so on. We are committed to reducing the cost of research with value, integrity and a truly personal buying experience. Products are available from affordable research quantities to larger bulk amounts for process development and production.
