Hallmark red cell proteins in erythroid cells differentiated from C19 iPSCs analysed by nanoLC-MS/MS.

Coverage; the percentage of the protein sequence covered by identified peptides. PSMs; the total number of identified peptide sequences for the protein. Peptides; the number of peptide sequences identified. Score; the total score of the protein which is the sum of all peptide Xcorr values above the specified score threshold. Note, peptide number is not a measure of protein abundance as different peptides, in particular some of those from integral membrane proteins, are difficult to detect by MS.
