update labhead Developing Dynamic MRM Method for Agilent MassHunter for proteins Q6PI98, Q8N2U9, Q96DM3, Q9H3N8 for researching proteome of 18th chromosome. Normal human liver tissue extracted proteins lysis in HFIP 20%; after reduction, alkylation and sigestion with trypsin, final concentration 1 ug/ul, original concentration 12.6 ug/ul. Normal human plasma lysis in HFIP 20% after immunodepletion on Hu-14 column, reduction, alkylation and digestion with trypsin; the original concentration befor immunodepletion 53.17 mg/ml, after - 24.89 mg/ml (concentrated); in sample - 1 mg/ml.
