By using Peptide mass fingerprint analysis of 6 purified proteins which had been added with DTT, iodoacetamide, and digested with Trypsin, We found their mass as following in this link.

Then find the names of 6 proteins and their accession numbers after that calculate their pIs and molecular weights.

 

The results show in this table
