IgM (Fc specific) polyclonal FITC, anti-caprine

Quantity: 200 µl

Background:
The reactivity of the antiserum is directed to the Fc subunit of the IgM molecule which expresses strict isotypic (class) specificity. It does not react with any non-Ig protein in goat serum, as tested by immunoelectrophoresis and double radial immunodiffusion. In immunocytochemical and immunohistochemical staining for the detection of IgM at the cellular and subcellular level by staining of appropriately treated cell and tissue substrates; to demonstrate circulating IgM antibodies in serodiagnostic microbiology and autoimmune diseases; to identify a specific antigen using a reference antibody of goat origin known to be of the IgM isotype 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.

Isotype: Rabbit Polyclonal

Source: Purified normal IgM isolated from pooled goat serum. Freund's complete adjuvant is used in the first step of the immunization procedure.

Form: Fluorescein-coupled purified hyperimmune rabbit IgG, in phosphate buffered saline (PBS, pH 7.2).

Reactivity: Caprine

Cross Reactivity:
Inter-species cross-reactivity is a normal feature of antibodies to immunoglobulins, since Ig of different species frequently share antigenic determinants. Cross-reactivity of this antiserum has not been tested in detail, however a strong reaction with Sheep IgM has been observed.

Applications: ELISA, Immunocytochemistry, Immunohistochemistry (frozen), (In)direct immunofluorescence

Storage: Store at 4C, or in small aliquots at -20C.
