CD44 Iis a a 100kD glycoprotein widely expressed on human leucocytes, white matter of the brain and by some epithelial cells of the intestine and of the breast. 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.

Applications:
Suitable for use in Flow Cytometry, Immunohistochemistry, and Immunoprecipitation. Other applications not tested.

Recommended Dilutions:
Immunohistochemistry (paraffin): Requires protein digestion pre-treatment of paraffin sections e.g. trypsin or pronase. Use sodium citrate buffer, pH 6, for heat mediated antigen retrieval.
