Product details
- Chemical name: (3S,4R,5S,8R,9E,12S,14S,15R,16S,18R,19R,26aS)-5,6,8,11, 12,13,14,15,16,17,18,19,24,25,26,26a Hexadecahydro-5,19 - dihydroxy-3-[(1E)-2-[(1R,3R,4R)-4-hydroxy-3-methoxycyc lohexyl]-1- methylethenyl]-14,16-dimethoxy-4,10,12,18-te tramethyl-8-(2-propen-1-yl)- 15,19-epoxy-3H-pyrido[2,1-c ][1,4]oxaazacyclotricosine-1,7,20,21(4H,23H)tetrone
- Also known as: Tacrolimus, Fujimycin
- CAS number: 104987-11-3
- Molecular formula: C44H69NO12.
- Purity: >98%
- Concentration: 10 pM - 50 nM.
- Form: Lyophilized powder.
- Solubility: DMSO or ethanol. Centrifuge all product preparations before use (10000 x g 5 min).
- 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. For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in sterile water at a concentration of at least 0.1 mg/mL. 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. It is recommended to prepare fresh solutions in working buffers just before use. For long-term storage of diluted solutions, we recommend adding 0.1% BSA. Repeat freeze-thawing may result in loss of activity.
- 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.

Scientific background
FK 506 (Tacrolimus), a macrolide compound isolated from Streptomyces tsukubaensis, is a potent immunosuppressive compound that inhibits T-cell activation and is an inhibitor of fungal growth (10 to 100 times more potent than Cyclosporin A).1-3 FK-506 binds and inhibits, in vitro, the activity of immunophilin proteins known as FK 506-binding protein (FKBP), in a variety of organisms, ranging from yeast to humans.4-8Immunosuppression activity of FK-506 seems to be due to FK-506/FKBP complex that inhibits the heterodimeric Ca2+/calmodulin-dependent phosphatase Calcineurin. This, in turn, prevents the Calcineurin-dependent activation of interleukin-2 transcription and T-cell proliferation.9-12 FK-506 inhibits FKBP activities, increases sarcoplasmic reticulum Ca2+ release and decreases the ability of Na+/Ca2+ exchange to extrude Ca2+ from the cell.13
