Description: The Psel.KO2.3 monoclonal antibody reacts with mouse CD62P (also known as P-selectin and GMP-140), a 140-kDa cell adhesion molecule that can be induced on endothelial cells and platelets. During inflammation, this selectin mediates adhesion of monocytes and neutrophils to activated platelets, as well as leukocyte rolling on endothelial cells. The major ligand for CD62P on neutrophils is P-selectin glycoprotein ligand-1 (PSGL-1). This monoclonal antibody recognizes an epitope that is conserved across several species (e.g. mouse, human, and rat) and has not been reported to block cell adhesion. Applications Reported: This Psel.KO2.3 antibody has been reported for use in flow cytometric analysis. Applications Tested: This Psel.KO2.3 antibody has been tested by flow cytometric analysis of human platelets. This can be used at less than or equal to 0.125 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. PerCP-eFluor® 710 emits at 710 nm and is excited with the blue laser (488 nm); it can be used in place of PerCP-Cyanine5.5. We recommend using a 710/50 bandpass filter, however, the 695/40 bandpass filter is an acceptable alternative.Please make sure that your instrument is capable of detecting this fluorochrome. Fixation: Samples can be stored in IC Fixation Buffer (cat. 00-8222) (100 µL cell sample + 100 µL IC Fixation Buffer) or 1-step Fix/Lyse Solution (cat. 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically. Excitation: 488 nm; Emission: 710 nm; Laser: Blue Laser. Filtration: 0.2 µm post-manufacturing filtered. P-selectin is a 140 kDa type 1 transmembrane glycoprotein, and is one of the most commonly studied proteins that regulate cell rolling. P-selectin is stored in the Weibel-Palade bodies of endothelial cells, as well as in a-granules of platelets. From there, it can be rapidly brought to the cell surface after exposure to thrombin, histamine, complement 5a, Ca21 ionophores, or adenosine diphosphate.
