FC - Quality tested

Application Notes:

Clone IM7 has been reported to recognize an epitope common to alloantigens and all isoforms of CD4417,18 that is located between amino acids 145 and 18620. Additional reported applications (for the relevant formats) include: immunohistochemistry of acetone-fixed frozen sections and formalin-fixed paraffin-embedded sections6,7, complement-mediated cytotoxicity1, immunoprecipitation1,3, and in vivo inhibition of DTH4,5.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

C57BL/6 mouse splenocytes stained with IM7 PE/Cy7



Description:

CD44 is a 80-95 kD glycoprotein also known as Hermes, Pgp1, H-CAM, or HUTCH. It is expressed on all leukocytes, endothelial cells, hepatocytes, and mesenchymal cells. As B and T cells become activated or progress to the memory stage, CD44 expression increases from low or mid levels to high levels. Thus, CD44 has been reported to be a valuable marker for memory cell subsets. High CD44 expression on Treg cells has been associated with potent suppressive function via high production of IL-10. CD44 is an adhesion molecule involved in leukocyte attachment to and rolling on endothelial cells, homing to peripheral lymphoid organs and to the sites of inflammation, and leukocyte aggregation.

Other Names: Hermes, Pgp-1, H-CAM, HUTCH-1, ECMR III, gp85, Ly-24
Structure: Variable splicing of CD44 gene generates many CD44 isoforms, 80-95 kD
Distribution: All leukocytes, epithelial cells, endothelial cells, hepatocytes, mesenchymal cells
Function: Leukocyte attachment and rolling on endothelial cells, stromal cells and ECM
Ligand Receptor: Hyaluronan, MIP-1β, fibronectin, collagen
