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 heavy chain of rat IgM but not with rat IgG or the light chains of rat 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 human serum proteins, but it may cross-react with IgM from other species.
Physical State: Sterile-filtered liquid
Storage: Store at 2-8°C under sterile conditions. Prepare working dilution fresh each day.
Expiration date: one year from date of receipt. However, the expiration date may be extended if the product is stored according to the recommendation and the test results are acceptable for its intended use.
The antibody was purified from antisera by immunoaffinity chromatography using antigens coupled to agarose beads.

Suggested Working Concentration or Dilution Range:
10-20 µg / ml
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.
