Background

Gab2 (Grb2-associated binder-2) is an adaptor protein involved in numerous intracellular signaling pathways via its interaction with receptor tyrosine kinases (RTKs), growth factors and cytokines. Gab2 is a substrate of various RTKs, including EGFR, insulin receptor, cytokine receptors as well as B and T cell antigen receptors; Gab2 acts as a docking protein for several SH2-containing proteins (1-3). Upon tyrosine phosphorylation, Gab2 interacts with SHP2 tyrosine phosphatase and GRB2 adaptor protein PI3-kinase, CrkL and SHC (4-5).

Molarity Calculator

Calculate the mass, volume, or concentration required for a solution.

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)

As an example, if the molecular weight of a compound is 197.13 g/mol and the desired concentration is 10 mM for 10 ml of water based stock solution, the required mass would be = 19.713 (value determined by this calculator).
