low complexity QC sample metric QC1 sample metric MS MS:4000077 A QC metric based on the results of a QC1 sample measurement. A QC1 sample is made from trypsin-digested BSA MS Standard (CAM modified), see Pichler et al. Chiva et al. for details on QC sample design). Expected peptides from QC1 sample measurement are: 'LVNELTEFAK','HLVDEPQNLIK','VPQVSTPTLVEVSR','EAC(Carbamidomethyl)FAVEGPK','EYEATLEEC(Carbamidomethyl)C(Carbamidomethyl)AK','EC(Carbamidomethyl)C(Carbamidomethyl)HGDLLEC(Carbamidomethyl)ADDR','SLHTLFGDELC(Carbamidomethyl)K','TC(Carbamidomethyl)VADESHAGC(Carbamidomethyl)EK','YIC(Carbamidomethyl)DNQDTISSK','NEC(Carbamidomethyl)FLSHK'
