MtoZ Biolabs has launched the LC-MS/MS C-peptide quantification service which enables highly sensitive, accurate, and reproducible quantification of C-peptide levels in various biological sample types. This service is widely applied in studies of cellular secretion, metabolic mechanism exploration, and multi-condition sample comparison, providing reliable data support for investigating C-peptide fluctuations and evaluating related experimental systems.
Overview
C-peptide is the connecting peptide released when proinsulin is processed into mature insulin. Due to its longer half-life and higher stability, it is commonly used as an important indicator for assessing endogenous insulin secretion. Its measurement is not affected by exogenous insulin and therefore more accurately reflects pancreatic beta-cell secretory activity. LC-MS/MS offers high sensitivity and specificity, enabling precise and reliable C-peptide quantification even in complex sample matrices, and provides robust data support for related research.
