This antibody recognizes an epitope that is common to all CD44 isoforms.
Heat-mediated antigen retrieval using a sodium citrate buffer (pH 6.0) is recommended for the staining of paraffin sections. For FACS analysis, use 10ul of the suggested working dilution to label 1x10^6 cells in 100ul.
CD44 cell surface antigen is a 100kDa glycoprotein widely expressed on human leucocytes, white matter of the brain and by some epithelial cells of the intestine and breast. Several isoforms of CD44 exist, including the predominant CD44H isoform detected in many normal tissues. CD44 is a receptor for hyaluronic acid (HA) and is involved in cell-cell interactions, cell adhesion and migration. CD44 also participates in a wide variety of cellular functions including lymphocyte activation, recirculation and homing. CD44 expression may be up-regulated upon some carcinomas, and it has been speculated that this may be related to metastatic potential.

Opposing effects of high- and low-molecular weight hyaluronan on CXCL12-induced CXCR4 signaling depend on CD44.
MA1-83947 was used in blocking or activating experiment to study the role of CD44 in mediating the opposing effects of high- and low molecular weight species of hyaluronan on CXCL12-induced CXCR4 activation in HepG2 and HUVEC cells
