-
aPepuniq is the number of unique peptide used to the protein identification.
-
b-Log (e) is the expectation value of protein identification by X!Tandem.
- Identification score of protein k (ID_S(P
k
)) was calculated as a sum of each scores obtained from each replicates. When n = 3 (triplicate), protein with ID_S(P
k
) ≥ 3 was considered present in a sample.
