Heavy-labeled Full-length Protein as MS Standards
Accurate quantification of human protein biomarkers
AMSBIO offers an extensive collection of Mass Spectrometry (MS) standards for human proteins. Produced in human HEK293T cells and labeled with [U- 13C6, 15N4]-L-Arginine and [U- 13C6, 15N2]-L-Lysine, these full length proteins with appropriate post-translational modifications are ideal identification and quantification standards.
