Mfr.No.	C-900, C-900_100 mg, C-900_25 mg
Description	Cyclosporin A (#C-900) is a highly pure, natural, and biologically active compound.
Molecular Formula	C62H111N11O12.
Synonyms	Natural
Background	Cyclosporin A is a hydrophobic, cyclic peptide isolated from Tolypocladium inflatum and is a potent immunosuppressant and antifungal compound. It acts via its ability to bind a family of intracellular proteins, the cyclophilins (intracellular peptidyl-prolyl cis-trans isomerases), which are abundant, ubiquitous, highly conserved, and found in multiple forms in different intracellular compartments.1 In yeast, Cyclophilin A, an 18-kDa cytoplasmic protein, mediates Cyclosporin A actions.2,3The immunosuppressive action of Cyclosporin A is mediated by the Cyclosporin A-Cyclophilin complex that specifically inhibits the Ca2+/calmodulin-dependent serine-threonine-protein phosphatase-2B (Calcineurin).4-10 This, in turn, inhibits Calcineurin and promotes dephosphorylation of transcription factor NF-AT and T cell activation.11-14 In vivo, Cyclosporin A-induced hypertension involves the attenuation of endothelium-derived NO production through the inhibition of Calcineurin-sensitive pathways regulating eNOS dephosphorylation.15Cyclosporin A has been shown to alter cell proliferation in different systems. For hematopoietic progenitor stem and progenitor cells, smooth muscle cells, and hepatocytes, it serves as an inducer of cell proliferation or as a tumor promoting effector.16-18 On the other hand, growth of interleukin-3-dependent mast cells, human lung-cancer cells, tubular kidney cells, cultured pituitary cells, T-cells, and keratinocytes were inhibited by Cyclosporin A.19-21 Moreover, Cyclosporin A has been observed in vitro and in vivo as an antimalarial agent, but the exact mechanism is not yet clear.22
Shipping	Shipped at room temperature. Product as supplied can be stored intact at room temperature for several weeks. For longer periods, it should be stored at -20°C
Concentration	10-500 nM.
Reconstitution	Centrifuge the vial before adding solvent (10,000 x g for 5 minutes) to spin down all the powder to the bottom of the vial. The lyophilized product may be difficult to visualize. Add solvent directly to the centrifuged vial. Tap the vial to aid in dissolving the lyophilized product. Tilt and gently roll the liquid over the walls of the vial. Avoid vigorous vortexing. Light vortexing for up to 3 seconds is acceptable if needed. The product is soluble in pure water at high micromolar concentrations (100 uM - 1 mM). For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in double-distilled water (ddH2O) at a concentration between 100-1000x of the final working concentration. Divide the stock solution into small aliquots and store at -20°C. Before use, thaw the relevant vial(s) and dilute to the desired working concentration in your working buffer. Centrifuge all product preparations before use. It is recommended to prepare fresh solutions in working buffers just before use. Avoid multiple freeze-thaw cycles to maintain biological activity
Cas Number	59865-13-3

Storage	Storage After Reconstitution: The reconstituted solution can be stored at 4°C for up to 1 week. For longer periods (up to 6 months), small aliquots should be stored at -20°C. We do not recommend storing the product in working solutions for longer than a few days. Avoid multiple freeze-thaw cycles. Storage before Reconstitution: The product is shipped as a lyophilized powder at room temperature. Upon receipt, store the product at -20°C. Protect from moisture. Storage of solutions: Up to two weeks at 4°C or six months at -20°C.
