Animal Immunoglobulins
REDUCE NON-SPECIFIC BINDING - MINIMIZE BACKGROUND SIGNAL - USE AS POSITIVE CONTROL
Scripps Laboratories offers a variety of purified, stable Animal IgGs. These products are useful in the development of antibody-based immunoassays, being used as a standards and controls or helping to reduce the non-specific binding that increases background signal and clouds results. Animal IgGs are also useful in basic research as controls in techniques such as western blot (WB), immunohistochemistry (IHC), immunoprecipitation (IP), and other antibody-based assays.
