Once reconstituted with bacteriostatic water, vials must be maintained at temperatures between 2C and 8C

For laboratory and research purposes only.

For these reasons, PregS more closely resembles the characteristics of classical neurotransmitters, such as acetylcholine, in which the parent molecule bears a full positive charge and is active only at an extracellularly directed recognition site while the immediate breakdown products (choline + acetic acid) are inactive

This technique is a lifesaver for peptides that are right on the edge of solubility
