AnaSpec, one of the world’s leading providers of custom and catalog peptides, has introduced ClearPoint™ Peptides, heavy isotope-labeled peptides for absolute quantitation (AQUA) of proteins.

The use of mass spectrometry (MS) has helped advanced proteomics research by providing qualitative information of thousands of known and unknown proteins. By spiking protein tryptic digests with internal heavy isotope labeled peptide standards, MS becomes an absolute quantitation (AQUA) method.1

AnaSpec’s ClearPoint™ peptides offer a choice of heavy hydrogen (2H), carbon (13C), or nitrogen (15N)-isotopes specifically labeled at single, multiple or universal positions. They are available as both custom or catalog peptides.
