Sigma-Aldrich Creates AQUA Peptide Partnership Program for Customers

NEW YORK (GenomeWeb News) — Sigma-Aldrich today said that proteomic researchers ordering custom absolute quantitation peptides from the company will be invited to join its newly formed AQUA Peptide Partnership Program.
In addition, AQUA peptide sequences will be added to Sigma-Aldrich's growing AQUA Peptide Library, and contributors will receive partnership pricing on their custom orders, the company said.
The AQUA Peptide Library, initially developed in collaboration with the Protein Quantitation Consortium, will contain hundreds of AQUA Peptides, Sigma said.
Sigma-Aldrich said the AQUA initiative “enables focused, quantitative mass spectrometric studies” of protein biomarkers and amino acids.
The company said the technique also allows researchers to use mass spectrometry to validate gene silencing at the protein level.
The program is a response to “the need within the proteomics community for a sizable library of stable-isotope labeled tryptic peptides,” Jennifer Williams, Sigma-Aldrich’s quantitative proteomics product manager, said in a statement.
