CD22 Rabbit Polyclonal Antibody

Specifications

Product Data
Applications	ELISA, WB
Recommend Dilution	Indirect ELISA: To detect hCD22 (using 100 μl/well antibody solution) a concentration of 0.5 - 2.0 μg/ml of this antibody is required. In conjunction with compatible secondary reagents, it allows the detection of at least 0.2 - 0.4 ng/well of recombinant hCD22. Sandwich ELISA: To detect hCD22 (using 100 μl/well antibody solution) a concentration of 0.5 - 2.0 μg/ml of this antibody is required. In conjunction with Biotinylated Anti-Human CD22 as a detection antibody, it allows the detection of at least 0.2 - 0.4 ng/well of recombinant hCD22. Western blot: To detect hCD22 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.

Background	CD22 is a type 1 integral membrane glycoprotein with molecular weight of 130 to 140kD. It 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. There are two different isoforms of CD22. It exists predominantly as a monomer of the beta isoform but can also be found as a heterodimer composed of the beta isoform and a second, shorter isoform (CD22 alpha).
Synonyms	SIGLEC2, Siglec-2, B-cell receptor CD22, Leu-14, BL-CAM
Note	Centrifuge vial prior to opening.
