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 Melanoma cell lineS were lysed in 8M urea/100mM Ammonium bicarbonate buffer. The equivalent of 200,000 cells were loaded onto an SDS gel.
