Antigen Background
CD62L, a glycoprotein and member of the selectin family of adhesion receptors, is constitutively expressed on all classes of leukocytes including lymphocytes, monocytes, and polymorphonuclear cells. It is expressed on myeloid progenitor cells, erythroid precursor cells, and some thymocytes.
Immunogen
human PHA-activated peripheral blood mononuclear cells.
Preparation Note
Prepared by conjugation to fluorescein isothiocyanate isomer I (FITC). This green dye is efficiently excited at 495 nm and emits at 525 nm.
Specificity
Recognizes the CD62L (L-Selectin, LAM-1, Leu8, TQ1, LECAM-1, LECCAM-1, DREG) surface antigen. The antibody recognizes an epitope localized to the lectin domain. It inhibits “rolling” interactions and significantly reduces the binding of FITC-yeast phosphomannan monoester core polysaccharide to lymphocytes, monocytes and neutrophils.
