Purity:Purified by Protein A/G affinity chromatography.
Form:Supplied as a liquid in PBS, pH 7.4, 15mM sodium azide.
Specificity:Recognizes human Protein S. Reacts strongly with Protein S. Strong reaction is seen in sandwich ELISA in combination with a biotin-labeled antibody against protein S. Reactivity is Ca2+ dependent and is optimal when using Tris buffer containing 1mM calcium chloride. In Dot Blot, SDS-treatment abolishes the reactivity.
