AnaSpec last week introduced its newest ClearPoint heavy or isotope-labeled peptides and amino acids.

The peptides can be used for the quantitative analysis of beta-amyloid peptides in biological fluids using mass spectrometry. Beta-amyloid peptides have been used as biomarkers for Alzheimer's disease. ELISAs have been used to quantify these peptides, but technical challenges such as the tendency of beta-amyloids to self-aggregate, undergo post-translational modification, or bind to other proteins can lead to inaccurate results, AnaSpec said in a statement.

"The inclusion of internal heavy isotope labeled peptide standards makes mass spectrometry an absolute quantitation method for the peptide of interest," the company said.
