Full biological activity determined by a chemotaxis bioassay using human T-lymphocytes is in a concentration of 10-100 ng/ml. Appearance
Lyophilized powder. Formulation
Lyophilized after extensive dialysis against 20 mM PB, pH 7.4, 150 mM NaCl. Endotoxin Level
<1 EU/μg, determined by LAL method. Reconstitution
Reconstitute the lyophilized recombinant Human Lymphotactin/XCL1 (rHuLymphotactin/XCL1) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1% BSA. Storage & Stability
Lyophilized recombinant Human Lymphotactin/XCL1 (rHuLymphotactin/XCL1) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping
Room temperature in continental US; may vary elsewhere. Background
XCL1 is expressed by various immune cells, including activated CD8þ T cells, CD4þ T cells, NK cells, NKT cells, gd T cells, and thymic medullary epithelial cells. XCL1 elicits its chemotactic function by binding to the receptor called XCR1. XCR1 is expressed by a dendritic cell (DC) subpopulation. The interaction between XCL1 and XCR1 plays an important role in DC-mediated immune response and thymic development of regulatory T cells[1]. |
