All peptides sold by Tocris are supplied by net peptide weight. Peptides may contain counterions and residual water. To compensate for this our peptides are weighed so that the amount of peptide received is exactly that stated on the vial. The exact value is printed on the datasheet accompanying the product.
Most peptides are soluble in distilled water.
Sonication can also be a useful aid for solubilising peptides. If you would like to make any comments about this website then please use the Comments page provided.
