Invitrogen™ CD35 Monoclonal Antibody (E11)

Mouse Monoclonal Antibody

Brand:  Invitrogen™ MA516650

Product Code. 15215919

Description

Heat-mediated antigen retrieval using a sodium citrate buffer (pH 6.0) is recommended for the staining of paraffin sections. A suggested positive control for immunohistochemical applications is tonsil. For FACS analysis, use 10 μL of the suggested working dilution to label 1x10^6 cells in 100 μL. Mouse anti Human CD35 antibody, clone E11 recognizes complement receptor type 1, also known as CD35 or the C3b/C4b receptor.

CD35 (CR1, Complement Receptor 1) is a cell membrane-bound, monomeric glycoprotein and its primary function is to serve as the cellular receptor for C3b and C4b, the most important components of the complement system leading to clearance of foreign macromolecules. CD35 protein mediates cellular binding to particles and immune complexes that have activated complement. The CD35 complex is four different allotypes (C,A,B,D) C is 160 kDa; A is 190 kDa; B is 220 kDa and D is 250 kDa. CD35 is involved in the processing of immune complexes, promoting of binding and phagocytosis of C3b complexes and inhibition of complement activation. CD35 is on neutrophils, eosinophils, monocytes, B-cells, some NK-cells, erythrocytes, myeloid leukemias, follicular dendritic reticulum cells and is negative on basophils. Decreases in expression of CD35 protein and/or mutations in its gene have been associated with gallbladder carcinomas, mesangiocapillary glomerulonephritis, systemic lupus erythematosus and sarcoidosis. Mutations in the CD35 gene have also been associated with a reduction in Plasmodium falciparum rosetting, conferring protection against severe malaria. Alternate allele-specific splice variants encoding different isoforms of CD35 have been characterized. An additional secreted form of CD35 have also been described but has not been fully characterized.
