2.6 Calibration Curve of Standard

Description: A dilution series was done on the internal standard peptide from 50 Fmol to 0.1 fmol. Peptide detection was possible to 0.1 fmol.

 

Experiment Description: Cells from the Melanoma cancer cell line were lysed in RIPA buffer. The equivalent of 200,000 cells were loaded onto an SDS gel. The protein of interest was excised and ingel digestion with trypsin was performed after reduction and alkylation with TCEP and IAA. 1/6 of the resulting digest was then analyzed on a Thermo Scientific TSQ mass spectrometer.
