The Taiwanese ExPASy site, tw.expasy.org, is unavailable for maintenance. Please bookmark the addresses of the other mirror sites and use one of them during the downtime. We apologize for any inconvenience caused. MultiIdent MultiIdent is a tool that allows the identification of proteins using pI, Mw, amino acid composition, sequence tag and peptide mass fingerprinting data.
Instructions are available.
Please fill out the following form, then press the Perform button. Ala, Ile, Pro, Val, Arg, Leu, Ser, Asx, Lys, Thr, Glx, Gly, Met, His, Phe and Tyr. Currently, MultiIdent first generates a list of best-matching proteins by amino acid composition. This list is then used for the sequence tag and peptide mass fingerprinting parts of the program. As such, amino acid composition data must be entered for the unknown protein.
