Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Human sCD22. Anti-Human sCD22-specific antibody was purified by affinity chromatography and then biotinylated.
Sandwich ELISA: To detect hCD22 by sandwich ELISA (using 100 µL/well antibody solution) a concentration of 0.25-1.0 µg/mL of this antibody is required. This biotinylated polyclonal antibody, in conjunction with PeproTech Polyclonal Anti-Human CD22 (500-P227) as a capture antibody, allows the detection of at least 0.2-0.4 ng/well of Recombinant hCD22.
Western Blot: To detect hCD22 by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 µg/mL. Used in conjunction with compatible secondary reagents the detection limit for Recombinant hCD22 is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions.
500-P227BT-1MG will be provided as 2 x 500 µg
靶标信息
CD22 (BL-CAM) is a type 1 integral membrane glycoprotein with molecular weight of 130 to 140 kDa. CD22 is expressed in both the cytoplasm and cell membrane of B-lymphocytes. CD22 antigen appears early in B-cell lymphocyte differentiation at approximately the same stage as the CD19 antigen. Unlike other B-cell markers, CD22 membrane expression is limited to the late differentiation stages comprised between mature B cells (CD22+) and plasma cells (CD22-), and may thus prove useful in phenotyping mature leukemias. CD22 is also strongly expressed in hairy cell leukemia. CD22 preferentially binds to alpha2,6-linked sialic acid. The sialic acid recognition site can be masked by cis interactions with sialic acids on the same cell surface. Upon ligand induced tyrosine phosphorylation in the immune response seems to be involved in regulation of B cell antigen receptor signaling. CD22 plays a role in positive regulation through interaction with Src family tyrosine kinases and may also act as an inhibitory receptor by recruiting cytoplasmic phosphatases via their SH2 domains that block signal transduction through dephosphorylation of signaling molecules. CD22 is also strongly expressed in hairy cell leukemia. CD22 is also positive in diffuse large B-cell lymphoma and nodular lymphocyte predominance Hodgkin’s lymphoma, but negative in classical Hodgkin’s lymphoma.
