Custom Premix Selecting "Custom Premix" option means that all of the beads you have chosen will be premixed in manufacturing before the kit is sent to you.
A cell-permeable pyridinecarbonitrile compound that acts as a potent, ATP-competitive (Ki = 79 nM, using PKCθ KD in coupled PK/LDH assays), and isozyme-selective PKCθ inhibitor (IC50 = 70 nM) with much reduced potency against other novel PKCs (IC50 = 0.35, 2.33, and 16.35 µM against δ, ε, and η isoforms, respectively) and little or no activity against the conventional PKCβ and atypical PKCζ (IC50 >50 µM) as well as a panel of 18 other commonly studied cellular kinases (IC50 >10 µM). Shown to preferentially inhibit IL-2 production from anti-CD3- and anti-CD28-activated T cells derived from wild-type over PKCθ-knockout mice (IC50 = 58 and 231 nM, respectively).
