The antibody was purified by affinity chromatography and conjugated with FITC under optimal conditions. The solution is free of unconjugated FITC and unconjugated antibody.
Mouse Qa-2 is a 40 kD GPI-linked surface protein. It is a member of nonclassical MHC class Ib molecule encoded by Q5, Q6, Q7, Q9, and Q10 genes of the H-2 complex. Qa-2 is a nonpolymorphic molecule primarily expressed on mouse T and B cells. The expression level of Qa-2 on mature T cells is higher than on B cells. Different mouse strains express Qa-2 at varying levels. Qa-2, in association with β2-microglobulin, binds to peptide and plays a role in antigen presentation.
