Description

Description: Whole IgG antibodies are isolated as intact molecules from antisera by immunoaffinity chromatography. They have an Fc portion and two antigen binding Fab portions joined together by disulfide bonds and therefore they are divalent. The average molecular weight is reported to be about 160 kDa. The whole IgG form of antibodies is suitable for the majority of immunodetection procedures and is the most cost effective. Based on immunoelectrophoresis and/or ELISA, the antibody reacts with the Fc5µ portion of the human IgM heavy chain but not with human IgG, IgA, or the light chains of human immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins. The antibody has been tested by ELISA and/or solid-phase adsorbed to ensure minimal cross-reaction with bovine and horse serum proteins, but it may cross-react with IgM from other species.

Short Description

Donkey Anti-Human IgM, Fc5μ fragment secondary antibody, conjugated to Biotin-SP (long spacer). This is an affinity purified whole IgG polyclonal antibody and has been tested and/or adsorbed to ensure minimal cross reactivity with Bovine and Horse serum proteins.

Application Notes

1:20,000 - 1:400,000 for ELISA and Western blotting using enzyme-conjugated streptavidin 1:500 - 1:5,000 for enzyme immunohisto/cytochemistry 1:200 - 1:1,000 for flow cytometry and fluorescence immunohisto/cytochemistry Dilution factors are presented in the form of a range because the optimal dilution is a function of many factors, such as antigen density, permeability, etc. The actual dilution used must be determined empirically.

Storage Note

Storage and Rehydration: Store freeze-dried solid at 2-8°C. Rehydrate with the indicated volume of dH2O and centrifuge if not clear. Prepare working dilution on day of use. Product is stable for about 6 weeks at 2-8°C as an undiluted liquid. Extended Storage after Rehydration: Aliquot and freeze at -70°C or below. Avoid repeated freezing and thawing. Alternatively, add an equal volume of glycerol (ACS grade or better) for a final concentration of 50%, and store at -20°C as a liquid. Expiration date: one year from date of rehydration. The expiration date may be extended if test results are acceptable for the intended use.
