Goat Guinea Pig IgG (subclass specific), conjugated with FITC Antibody

Fluorescein isothiocyanate-conjugated IgG fraction of polyclonal goat antiserum to guinea pig IgG1, subclass specific. To identify and measure IgG1, antigen or antibody, at the cellular and subcellular level by immuno- fluorescence staining of appropriately treated cell and tissue substrates, and to demonstrate circulating antibodies in serodiagnostic microbiology and autoimmune diseases; to identify a specific antigen or immune complex using a reference antibody of guinea pig origin in the middle layer of the indirect test procedure. This immunoconjugate is not pre-diluted. The optimum working dilution of each conjugate should be established by titration before being used. Excess labelled antibody must be avoided because it may cause high unspecific background staining and interfere with the specific signal. Working dilutions are usually between 1:20 and 1:80.
