The histogram of log10 precursor intensity of the C4B-peptide (NGFKSHALQLNNR) by random and independent sampling over incubation of EDTA plasma on ice versus room temperature over time. The precursor ion intensity filter of 1000 counts was imposed before examining the precursor with the fitting algorithms. Random and independent sampling showed a 10-fold to 100-fold increase in C4B-peptide detection with incubation at room temperature
