Recombinant Human Selectin L, Fc-His

• Cat.No.: SELL-1660H
• Product Overview: Recombinant Human SELL was expressed inNSOcells. The extracellular domain of human L-Selectin (amino acid residues 1-332) was fused to the carboxy-terminal 6X his tagged Fc region of human IgG1 via a polypeptide linker.

Specification

• Species: Human
• Source: Mammalian Cells
• Tag: Fc&His
• Protein Length: 1-332 a.a.
• Description: L-selectin, also known as CD62L, is a cell adhesion molecule consisting of a large, highly glycosylated, extracellular domain found on leukocytes. It belongs to the selectin family of proteins, which recognise sialylated carbohydrate groups. L-selectin acts as a "homing receptor" for leukocytes to enter secondary lymphoid tissues via the high endothelial venules. L-selectin is an effective marker for separating lymphoid progenitors from myeloid progenitors and hematopoietic stem cells in bone marrow.
• Molecular Weight: The predicted molecular weight of Recombinant Human L-Selectin is Mr 60.4 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 90-100 kDa under reducing conditions.
• State Of Matter: Lyophilized.
• Formulation: This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco's phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.
• Purity: >90% by SDS Page and analyzed by silver stain.
• Endotoxin: <1.0 EU/µg as determined by the LAL method.
• Biological Activity: The biological activity of Human L-Selectin was determined by the ability of the immobilized protein to support the adhesion of LS180 cells, a human colon adenocarcinoma cell line. When 1 x 104 cells/well are added to human L-Selectin coated plates (10 μg/ml with 100 μl/well), approximately 90 - 100% will adhere for 1 hour incubation at RT.
• Storage And Stability: This lyophilized protein is stable for six to twelve months when stored desiccated at -20℃ to -70℃. After aseptic reconstitution, this protein may be stored at 2℃ to 8℃ for one month or at -20℃ to -70℃ in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
