The SK11 monoclonal antibody specifically binds to CD62L which is also known as, L-selectin, Leukocyte-endothelial cell adhesion molecule 1 (LECAM1/LECAM-1), Leukocyte adhesion molecule 1 (LAM1/LAM-1), Lymph node homing receptor (LNHR), Leu-8, or TQ1. CD62L is an ~80 kDa type I transmembrane glycoprotein that belongs to the Selectin/LECAM family. CD62L is differentially expressed on T cells, B cells, monocytes, granulocytes, and a subset of NK cells. The CD62L molecule is the human homolog of the mouse lymph node homing receptor, MEL-14. CD62L plays a role in leucocyte binding to inflamed endothelium and extravasation, as well as mediating lymphocyte homing into peripheral lymphoid tissues through high endothelial postcapillary venules. Soluble CD62L can result from the proteolytic cleavage of cell surface CD62L during cellular activation or inflammation.
The antibody was conjugated to BD Horizon Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.
