2.6 Calibration Curve of Standard

Description: Peptide was diluted from 50 fmol down to 0.1 fmol and was detectale down to the lowest value

 

Experiment Description: Serum sample digest from healthy adult venous blood draw. Sample denatured in Urea, reduced and alkylated (20mM TCEP and 200mM IAA) and digested overnight with trypsin. Sample was diluted in 2% ACN with 0.1% formic acid and a total of 0.1 nanoliters of serum was injected onto column.
