Application Specific Antibodies and Reagents for Immunological Research

Innate immunity is the front line, non-specific and immediate response to pathogens and to the unrecognized self. As a part of the larger immune system, innate immunity comprises a variety of molecules, cell types and signaling cascades which typically do not adapt to previous infection or vaccination.

The innate immune system mediates its response to infection by several means including: direct pathogen destruction, identification and clearance of foreign substances, recruitment of immune mediators by biochemical signaling and stimulation of the adaptive immune response.

Bio-Rad provides an extensive collection of antibodies, reagents, controls and standards for innate immunity research.
