Polyclonal antibodies are made using several different immune cells. For applications such as therapeutic drug development that require large volumes of identical antibody specific to a single epitope, monoclonal antibodies are a better solution.

What are polyclonal antibodies and where do they come from?

Polyclonal antibodies (pAbs) are mixture of heterogeneous which are usually produced by different B cell clones in the body. They can recognize and bind to many different epitopes of a single antigen. Polyclonal antibodies are produced by injecting an immunogen into an animal.

Higher doses have been shown to be more effective in reducing infections in patients with histories of chronic or recurrent sinopulmonary infections.

Is High IgM serious?

Hyper IgM syndromes are caused by very rare, one-in-a-million, and potentially life-threatening genetic mutations that severely compromise the immune system and resulting in the individual’s inability to produce antibodies. Patients with hyper IgM are at significant risk for opportunistic and repeated infections.

What does IgM mean in a blood test?

Immunoglobulin M (IgM): Found mainly in blood and lymph fluid, this is the first antibody the body makes when it fights a new infection.
