2.6 Calibration Curve of Standard

Description: NONE

 

Experiment Description: Cells from Human Lung caner line HCC 827 were lysed in RIPA buffer on ice. 80ugs of the cell lysate was loaded onto a SDS gel. The protein of interest was excised and ingel digestion with trypsin was performed after reduction and alkylation with TCEP and IAA. 1/4 of the resulting digest was then analyzed on a Thermo Scientific TSQ mass spectrometer.
