L Selectin ELISA kits are assays designed to measure levels of the protein L-selectin in biological samples, such as plasma, serum, culture extracts, and cell lysates. L-selectin, encoded by the gene SELL in humans, is a cell adhesion protein notably expressed on the surface of leukocytes and blastocysts. It may also be known as CD62L, LAM1, and LECAM1. L-selectin plays a crucial role in both innate and adaptive immune responses by facilitating adhesion events between leukocytes and endothelial cells. These interactions are essential for the movement of monocytes and neutrophils into inflamed tissues. L-selectin is also expressed by lymphoid-primed hematopoietic stem cells and may contribute to the migration of these stem cells to primary lymphoid organs.
