Description TL-1A belongs to the TNF superfamily of ligands. It is expressed predominantly in endothelial cells, and to a lesser extent in the placenta, lung, kidney, skeletal muscle, pancreas, small intestine and colon. TL-1A inhibits endothelial cell proliferation and angiogenesis. Product information Synonyms TL1A; TNF-like 1 Accession O95150 Source E.coli-derived Human TL-1A protein,Leu72-Leu251. Molecular Weight Approximately 20.5 kDa Purity > 97% by SDS-PAGE. Endotoxin < 1.0 EU per 1μg of the protein by the LAL method. Formulation Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4, with 1% BSA. Reconstitution 1. We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile PBS, pH 7.4, with 0.1% BSA to a concentration of 0.1-1.0 mg/mL. 2.Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. 3.Further dilutions should be made in PBS, which must contain carrier proteins, such as 0.1% BSA, 10% FBS, 5% HSA, 5% trehalose, one of four options. Storage The product should be stored at -25~-15℃ for 1 year date of receipt. 1 month, 2 ~8 °C under sterile conditions after reconstitution. 3 months, -25~-15℃ °C under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
