Components:

45x Ab-conjugated beads (S5P11 - human sP-selectin Ab-bead). PN: A113275A. One vial containing 100 µL of anti-human sP-selectin conjugated to AimPlex Bead S5P11.

25x Biotin-detection (human sP-selectin Biotin-dAb). PN: A113275B. One vial containing 100 µL of biotinylated anti-human sP-selectin.

Lyophilized Standard Mix-Human Group 9 Panel A, 8-Plex. PN: HG9008A. One vial containing lyophilized recombinant human sFas, sICAM-3, sL-selectin, sP-selectin, sIL-1RI, sVEGFR1, sCD40, and sNCAM-1.  Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits.

Application: Optimal antibody pair and antigen standard for assaying human Human sP-selectin/sLECAM-3/sCD62P. Can be multiplexed with other analytes in Human Group 9.  To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

P-selectin is a protein that functions as a cell adhesion molecule (CAM) on the surfaces of activated endothelial cells, which line the inner surface of blood vessels, and activated platelets. In un-activated endothelial cells, it is stored in granules called Weibel-Palade bodies. In un-activated platelets P-selectin is stored in α-granules. Other names for P-selectin include Leukocyte-Endothelial Cell Adhesion Molecule 3 (LECAM3), CD62P, and Granule Membrane Protein 140 (GMP-140). This protein redistributes to the plasma membrane during platelet activation and degranulation and mediates the interaction of activated endothelial cells or platelets with leukocytes. The membrane protein is a calcium-dependent receptor that binds to sialylated forms of Lewis blood group carbohydrate antigens on neutrophils and monocytes. Diseases associated with SELP include intermittent claudication and arteriosclerosis obliterans.
