Long Peptides and Proteins

Range of chain length of long peptides and proteins: 30-200 amino acid residues
(Do not hesitate to contact us even when your peptide consists of over 200 residues.)

We have successfully synthesized green fluorescent protein (GFP) with 238 amino acids. [Proc. Natl. Acad. Sci. U.S.A., 95, 13549 (1998).]

Our Results

Purity of FRETS-VWF73 from other supplier


Do you think broadening of the peak on RP-HPLC analysis being the intrinsic property of the long peptide and protein? Peptide Institute, Inc. guarantees the purity of our synthetic long peptides and proteins to be high enough by applying several highly efficient analytical methods.
