Biological Activity

Description 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.
Targets
CK2 [1]
(Cell-free assay)
CK1 [1]
(Cel-free assay)
0.4 μM(Ki) 47 μM(Ki)
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). TBB discriminates between CK2 and CK1, being much more e¡ective with the former[1].

Protocol

Cell Research:

[1]

+ Expand
  • Cell lines: Jurkat cells
  • Concentrations: 60 μM
  • Incubation Time: 2 h
  • Method:

    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.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
