Cells grown in Lys8, Arg10
- Initial check on peptides –> using MQ peptides.txt
- considering only 0 missed cleavages to make the calculation straight forward (assuming enough peptide for sufficient statistical power - what is the minimum number of peptides appropriate?)
- these values are derived from the Ratio H/L data in peptides.txt
- we convert this to %H by taking (ratio H/L / 1+ratio H/L)*100
- Labeling efficiency should be ~95%, certainly better than 90% for using in an experiment
- secondary check on proteins –> using MQ proteingroups.txt
- good labeling is sufficient for mix after purification (MAP) SiLAC experiments
- this factor is used to determine the expected %H of a 50:50 (by protein quantity) mixture of heavy and light materials used in IDiRT (or mix before purification SiLAC, which we don't really do)
