JH295

Customer Review

Based on 1 Customer Validation

JH295 is a potent, irreversible and selective NIMA-related kinase 2 (Nek2) inhibitor with an IC₅₀ of 770 nM. JH295 inhibits cellular Nek2 via alkylation of Cys22. JH295 is inactive against the mitotic kinases, Cdk1, Aurora B or Plk1, and does not perturb bipolar spindle assembly or the spindle assembly checkpoint. JH295 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

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.
