Polyclonal Antibody Development Platform

Polyclonal antibodies are a heterogeneous mix of antibodies formed by a variety of B cells in the body. With a research team with extensive expertise in rare disease therapy research and development as well as an advanced therapeutic antibody development platform, our company is confident to provide customers with polyclonal antibody development services for rare diseases. We can provide one-stop personalized project management services according to customers' specific requirements.

Introduction to Polyclonal Antibody

Polyclonal antibodies are generally produced by immunizing a suitable mammal, such as a mouse, rabbit, or goat. If you want to collect more serum, you can use large mammals. First, specific antigens are injected into experimental animals to stimulate the host to produce a certain immune response and produce different types of antibodies in the blood. The antibodies stimulated by one antigen are called polyclonal antibodies. Animals are immunized secondary and tertiary to produce the highest titer of antibodies against the antigen. After a few weeks, polyclonal antibodies can then be collected and purified from the antisera.
