MK 1256

MK 1256 is a highly selective and orally active inhibitor of tissue protease K (Cat K) with an IC₅₀ of 0.62 nM. MK 1256 shows extremely high selectivity towards other tissue proteases (all > 1100 times), with only a slightly lower selectivity for tissue protease F (Cat F) (110 times). MK 1256 exhibits strong anti-bone resorption activity in the osteoporosis model of rhesus monkeys with ovariectomy. MK 1256 can be used for research on osteoporosis.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
