Background

POT1 (protection of telomeres 1), a telomere regulator, is a single-stranded telomeric DNA-binding protein that controls telomerase-mediated telomere elongation. Telomere maintenance is required for protection against changes in telomere length, which has been implicated in ageing and certain cancers. Specifically, this protein functions as a member of a multi-protein complex that binds to the TTAGGG repeats of telomeres, regulating telomere length and protecting chromosome ends from illegitimate recombination, catastrophic chromosome instability, and abnormal chromosome segregation. Excessive transcriptional expression of POT1 has been associated with stomach cancers.

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).
