Peptide Synthesis

New Simplified and Detailed peptide ordering instructions.

ALL PEPTIDES ARE PURIFIED!!!!!!

Typical purifications yield 10 - 15 mg of lyophilized, pure peptide.
dot

We guarantee > 97% purity.

Modified Peptides

dot Peptides coupled to either KLH or BSA for antibody production. ($150.00)
dot multiple antigenic peptides ( MAP )
dot degenerate peptides
dot phosphorylated peptides at ser, thr, or tyr residues
dot benzoylated peptides
dot amide peptides ( more closely resembles in vivo environment of parent protein )
dot biotinylated peptides
dot alkylated peptides ( e.g., carboxymethylated cysteine residues )
dot acylated peptides (e.g., additions to primary amino groups of lysine or free N terminus )
dot fluorescently tagged peptides

Analysis:

reverse phase high pressure liquid chromatography ( HPLC )
dot

matrix assisted laser desorption ionization time of flight mass spectrometry ( MALDI-TOF )
dot

amino acid analysis

Prices:

$195 set-up fee which includes synthesis reagents, cleavage reagents, analysis, and HPLC purification
dot

$20 per amino acid charge
dot

modified peptide prices vary but generally don't run much extra
dot

Outside DFCI, $295 Set up, $30 per amino acid.

Compare these prices to outside vendors. You may find a few that offer slightly lower costs per amino acid. In addition, some vendors ( e.g., research genetics ) do not charge a set-up fee. However, there will be large charges for purification. Also, turnaround time will be dramatically increased for purified peptides. The full array of analyses that we offer will not be performed on your peptide or will be offered at a substantial additional charge. There will also be a shipping fee. Specialty peptides, if offered, will be extremely costly. Don't take chances! Order from a lab that cares about your research.
