CD86(p2)-muIg Purified (Preservative-free)

Human CD86 (B7-2) is a costimulating ligand for CD28 and CTLA-4.  CD86 is expressed on activated B cells and blood monocytes (3). 

Molecular Structure:  A soluble fusion protein consisting of the extracellular (224 aa) domain of  human CD86 fused to murine IgG2a Fc.  Compared to CD86 reference sequence Genebank #HUMB72A, the following polymorphism is present:  I(185)V.  Ancell now has three polymorphic variants of CD86-muIg available (see attachment).
