NKL 22 is a potent and selective inhibitor of histone deacetylases (HDAC), with IC₅₀ values of 199 and 69 nM for HDAC1 and HDAC3, respectively. NKL 22 can reverse abnormal expression of HD‑related genes and restore the levels of key genes including Ppp1r1b in Huntington's disease transgenic mice. NKL 22 can be used for the researches of Huntington's disease and cancer.

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.
