Principle of the Assay: This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-L-Selectin polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-L-Selectin polyclonal antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the L-Selectin amount of sample captu red in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of L-Selectin can be calculated!!Background/Introduction: L-selectin, also known as CD62L, is a cell adhesion molecule found on lymphocytes. It belongs to the selectin family of proteins, which recognize sialylated carbohydrate groups. 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. L-selectin acts as a "homing receptor" for lymphocytes to enter secondary lymphoid tissues via high endothelial venules. Ligands present on endothelial cells will bind to lymphocytes expressing L-selectin, slowing lymphocyte trafficking through the blood, and facilitating entry into a secondary lymphoid organ at that point. It may also play a role in neutrophil adhesion to endothelium at sites of inflammation.

Product Notes
The Human MCP-2 mcpt2 (Catalog #AAA494796) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA494796 ELISA Kit recognizes Human MCP-2. It is sometimes possible for the material contained within the vial of "MCP-2, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
