ClearPoint™ - Heavy Isotope Labeled Peptides for Absolute Protein Quantitation


With ClearPoint™ peptides from AnaSpec, absolute protein quantitation has become a lot clearer.

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. With triple-stage validation (both mass spec & HPLC) and over 8 years of successful synthesis, ClearPoint™ peptides are the proven solution for optimum quality heavy isotope labeled peptides.
