小鼠L选择素Elisa试剂盒描述：

       L-selectin (SELL), also known as CD62L, is a cell adhesion molecule found on leukocytes. It belongs to the selectin family of proteins, which recognize sialylated carbohydrate groups. It is cleaved by ADAM17. SELL is a cell surface component that is a member of a family of adhesion/homing receptors which play important roles in leukocyte-endothelial cell interactions. The molecule is composed of multiple domains: one homologous to lectins, one to epidermal growth factor, and two to the consensus repeat units found in C3/C4 binding proteins. SELL acts as a "homing receptor" for leukocytes to enter secondary lymphoid tissues via high endothelial venules. Ligands present on endothelial cells will bind to leukocyte expressing SELL, slowing leukocyte trafficking through the blood, and facilitating entry into a secondary lymphoid organ at that point. ScienCell's mouse L-Selectin ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. Mouse L-Selectin-specific monoclonal antibodies are pre-coated onto 8 x 12 divisible strips. The mouse specific detection monoclonal antibodies are biotinylated. The test samples and biotinylated detection antibodies are subsequently added to the wells and then washed with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB is used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The intensity of yellow is proportional to the amount of mouse L-Selectin captured in strips.
