CD62L Rat anti-Mouse, BB515, Clone: MEL-14, BD

Description

• The MEL-14 monoclonal antibody specifically binds to CD62L (L-selectin), a 95 kDa (on neutrophils) or 74 kDa (on lymphocytes) receptor with lectin-like and Epidermal Growth Factor-like domains
• In the mouse, L-selectin is detected on most thymocytes, with the highest levels of expression on an immunocompetent subset and a population of dividing progenitor cells, and on peripheral leukocytes, including subsets of B and T lymphocytes, neutrophils, monocytes, and eosinophils
• This member of the selectin adhesion molecule family appears to be required for lymphocyte homing to peripheral lymph nodes and to contribute to neutrophil emigration at inflammatory sites
• L-selectin is rapidly shed from lymphocytes and neutrophils upon cellular activation; metalloproteinases may mediate the release of CD62L ectodomains from the cell surface
• The level of CD62L expression, along with other markers, distinguishes naive, effector, and memory T cells
• L-selectin binds to sialytaed oligosaccharide determinants on high endothelial venules (HEV) in peripheral lymph nodes
• In vitro studies have demonstrated that CD34, GlyCAM-1, and MAdCAM-1, all recognized by mAb MECA-79 (anti-mouse PNAd Carbohydrate Epitope, Cat
• No
• 553863), may be ligands for CD62L
• MEL-14 mAb blocks in vitro binding of lymphocytes to peripheral lymph node HEV and inhibits in vivo lymphocyte extravasation into peripheral lymph nodes and late stages of leukocyte rolling
• The antibody was conjugated to BD Horizon BB515 which was developed exclusively by BD Biosciences
• With an excitation max of 490nm and an emission max of 515nm, BD Horizon BB515 can be excited by the 488nm laser and detected in a standard FITC set (e.g
• 530/30-nm filter)
• This dye provides a much brighter alternative to FITC with less spillover into the PE detector.
