Background

Tau is a microtubule binding protein that promotes microtubule assembly and stability. Tau is found to be the major component of the paired helical filaments (PHFs) found in the brains of patients with Alzheimer disease (AD) (1,2). Tau is hyperphosphorylated in PHFs, and specific phosphorylation sites have been implicated in the loss of Tau's association with the membrane cortex during AD disease state, including Ser 199/202, Thr 231, and Ser 393/404 (3). Glycogen synthase kinase-3, or GSK-3, phosphorylates Tau on Ser 396 (4).

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Peptides and proteins are guaranteed for 3 months from date of receipt.

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).
