About this item
Thermo Scientific Pierce Peptide Retention Standard is a mixture of five c-terminal amide decapeptides that provide reference elution profiles in reverse-phase HPLC.
- Determine the relative order of peptide elution from a complex mixture
- Efficiently predict peptide elution profiles to simplify identification and save purification time
- Identify peptides of known amino acid composition on reverse phase HPLC columns
- Monitor column performance—efficiency, selectivity and resolution during column aging
- Evaluate reverse-phase supports of varying n-alkyl chain lengths and ligand densities
- Product is shipped at ambient temperature
The Peptide Retention Standard consists of five C-terminal amide decapeptides, denoted S1 to S5, having the generic formula Ac-Arg-Gly-X-X-Gly-Leu-Gly-Leu-Gly-Lys-Amide. Four of these peptides are Na-acetylated with the sequence variation as follows: Gly3-Gly4, Ala3-Gly4, Val3-Gly4 and Val3-Val4. The fifth peptide, Ala3-Gly4, contains a free Na-amino group. This mixture will provide 100-200 injections (approximately 0.1 mg of each peptide) at 0.1 AUFS at 210nm. The Peptide Retention Standard is supplied as a dry film in a sealed vial.
