Peptide Synthesis Services:

1) Ordinary linear peptide: Chain length over 100 amino acid residues, milligram to gram scale.

2) Simple modified peptides: free N-terminal acetylation, and terminal amidation

3) Complex modified peptide: lipopeptide, phosphopeptide (Ser, Thr, Tyr), cyclic peptide (lactam ring,

disulfide ring), a fluorescent labeled peptide (FAM, FITC), biotin-labeled peptides, peptide compound

(MAP ), etc.

4) Protein Crosslinking: KLH, BSA, OVA.

5) We could supply peptide containing special amino acid: Contains D-amino acids and a variety

of amino acid derivatives.

6) Purity range: Crude peptide, Desalination,> 70%,> 80%,> 85%,> 90%,> 95%,> 98%,> 99%.

7）Any other special peptides that you need.

Peptide Common Sense

1）Peptide generally needs to be stored from light, especially, at -20 degrees below for the long-term preservation, for the short term

2）Storage, it can be saved at 4 ℃. The room temperature is available for short transportation .The Peptide is stable at -20 ℃, especially

3）When stored in adesiccator after freezedried. Before being exposed to the air, the lyophilized polypeptide may be kept at room temperature, which will reduce the humidity. When it is unable to be freezed drying, small sample volume storage is the best way.As

4）For those peptide that contains Cys, Met or Trp, the dissolved oxygen buffer is necessary, for such peptide is easy to oxidate with air.

5）Before the closure of bottles, we need some nitrogen or argon gas, because they will reduce oxidation. While, the peptide which contains Gln or Asn is relatively getting degradable easily, and they have shorter storage period compared with the simple peptide without those problems.
