Guinea Pig IgG2 (subclass specific) goat polyclonal antibody, HRP

Applications This antibody can be used in Enzyme Immunocytochemical and Immunohistochemical staining for the detection of IgG2 at the cellular and subcellular level by staining of appropriately treated cell and tissue substrates.
To demonstrate circulating IgG2 antibodies in serodiagnostic microbiology and autoimmune diseases. To identify a specific antigen using a reference antibody of guinea pig origin known to be of the IgG2 isotype in the middle layer of the indirect test procedure In non-isotopic assay methodology (e.g. ELISA) to measure IgG2 in guinea pig serum or other body fluids. 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:
Histochemical and Cytochemical Use: 1/50-1/250.
ELISA and comparable non-precipitating antibody-binding assays: 1/1,000-1/5,0000.
Reactivities Guinea Pig
Conjugation HRP

Monkey IgA (Secretory component) goat polyclonal antibody, Biotin

Applications Tested in Immunoelectrophoresis, Double Radial Immunodiffusion and ELISA against a panel of appropriate secretions and purified Ig isotypes.
Can be used in Immunocytochemical and Immunohistochemical staining for the detection of free SC and secretory IgA at the cellular and subcellular level by staining of appropriately treated cell and tissue substrates. In non-isotopic assay methodology (e.g. ELISA) to identify and measure SC or secretory IgA in Monkey body fluids. As a second step an avidin or streptavidin conjugate of the user’s choice has to be used. 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:
Histochemical and Cytochemical Use: 1/50-1/200.
ELISA and comparable non-precipitating antibody-binding assays: 1/500-1/1,000.

Human IgG4 mouse monoclonal antibody, clone MRQ-44, Purified

Applications Immunohistochemistry on Frozen and Formalin-Fixed, Paraffin-Embedded Sections: 1/100-1/500. 
Preparation and Pretreatment:
1. Cut 3-4 μm section of formalin-fixed paraffin-embedded tissue and place on positively charged slides; dry overnight at 58°C.
2. Deparaffinize, rehydrate, and epitope retrieve; the preferred method is the use of Heat Induced Epitope Retrieval (HIER) techniques in conjunction with a pressure cooker. The preferred method allows for simultaneous deparaffinization, rehydration, and epitope retrieval. Upon completion, rinse with 5 changes of distilled or deionized water.
3. If using HRP detection system, place slides in peroxide block for 10 minutes; rinse. If using AP detection system, omit this step.
Positive Control: Tonsil.
