Purity:Purified by Protein G affinity chromatography.
Form:Supplied as a liquid in PBS, 0.1% BSA, 0.02% sodium azide.
Specificity:Recognizes free soluble (17kD) and membrane (26kD) human TNF-alpha. Inhibits the biological activity of soluble and membrane TNF-alpha. The antibody can be a useful tool to discriminate between receptor bound soluble (17kD) and the membrane (26kD) form of TNF-alpha.
