Donkey anti-Sheep IgG (H&L), Biotin conjugated, min, cross-reactivity to human, mouse, rabbit IgG

Donkey anti-sheep IgG (H&L), is a biotin conjugated secondary antibody which is reacting with sheep IgG (H&L) in immunological assays. Antibody is specially adsorbed against human, mouse, rabbit IgG. Antibodies are affinity purified using solid phase sheep IgG.

This antibody reacts with the heavy chains on sheep IgG and with the light chains on all sheep immunoglobulins based on immunoelectrophoresis.Minimum cross-reactivity is observed to non-immunoglobulin sheep serum proteins based on immunoelectrophoresis. Antibody is supplied in 10 mM sodium phosphate, 150 mM sodium chloride, pH 7.2, 1 % (w/v) BSA, Protease/IgG free and 0.1 % (v/v) Kathon CG is used as preservative. Use of sodium azide will inhibit enzymatic activity of horseradish peroxidase.BSA and milk have to be replaced by other blocking reagents, like doneky serum or commercial formulations which are free from bovine IgG.
