Net Peptide Weight

Some products from the Peptide Institute are distributed in premeasured vials. These are indicated by the suffix -s, or -v in their catalog number. The net peptide weight is precisely determined by amino acid analysis after acid hydrolysis, HPLC, and/or UV absorption, and the value is indicated clearly on the vial label. The indicated weight is only for the net peptide molecule, and the weights of any constituents (water or acetic acid) are excluded from the quantity. The amount of usable peptide meets and may exceed its advertised quantity.

Pricing

All prices are stated in U.S. dollars and are subject to change. However, any item whose price has risen more than ten percent from that listed in our current catalog will not be shipped without customer authorization. While we make every effort to keep the pricing up-to-date in our 2007-2008 catalog, there may be times this is not possible or as fast as we would like it to be. These prices are subject to change due to price increases, as well as decreases. Please call for current pricing or to request a bulk quotation. We appreciate your understanding.

How to Search

Our search engine follows the same search parameters as most of the major internet search engines. However, quotation marks are unnecessary for exact matches.
