Based on immunoelectrophoresis and or ELISA, the antibody reacts with the heavy chains on Human IgA, IgG and IgM and with light chains common to most human immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins but the antibody may cross-react with immunoglobulins from other species.

Store lyophilized product at 2-8 °C. After reconstitution, product is stable for several weeks at 2 -8 °C as an undiluted liquid. Prepare working dilution only prior to immediate use. For extended storage after reconstitution, we suggest the addition of an equal volume of glycerol (ACS or better grade) to make a final glycerol concentration of 50% followed by storage at -20°C, with or without aliquoting. Please note that the concentration of protein and buffer salts will decrease to one-half of the original after the addition of glycerol. Expiration date is one year from date of reconstitution.
