体内（毎回新しく調製した物を用意してください）

Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	2.150mg/ml (4.95mM)	Taking the 1 mL working solution as an example, add 50 μL of 43 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	0.350mg/ml (0.81mM)	Taking the 1 mL working solution as an example, add 50 μL of 7 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	TBB (4,5,6,7-tetrabromobenzotriazole) is a selective cell-permeable CK2 inhibitor with IC50 values of 0.9 and 1.6 μM for rat liver and human recombinant CK2 respectively.
in vitro	In the presence of 10 μM TBB (and 100 μM ATP) only CK2 was drastically inhibited (s85%) whereas three kinases (phosphorylase kinase, glycogen synthase kinase 3L and cyclin-dependent kinase 2/cyclin A) underwent moderate inhibition, with IC50 values one-two orders of magnitude higher than CK2 (IC50 = 0.9 μM). This compound discriminates between CK2 and CK1, being much more e¡ective with the former^[1].

	実験の流れ	Cell treatment was performed by incubation of cell suspension (~10×10⁶ cells/ml) for 2 h at 37℃ in the presence of 2 μM okadaic acid (OA) with the addition of protein kinase inhibitors where indicated. After incubations, cells were centrifuged and lysed for 15 min in ice-cold buffer consisting of 20 mM Tris^HCl pH 7.4, 2 mM EDTA, 2 mM EGTA, 10 mM 2-mercaptoethanol, 10% (v/v) glycerol, 1 mM Na3VO4, 0.05% Nonidet P-40, protease inhibitor cocktail, 10 mM NaF, 1 μM OA. The lysate was cleared by centrifugation for 10 min at 14 000 rpm.
