Peptide Synthesis and Purification
Peptide Synthesis Highlights:
- Aapptec Focus multi-peptide synthesizer
- Two synthesis scales
- HPLC Purification
- A variety of modifications can be done
- Ready-made peptides
Synthesis Scales and Pricing:
| Synthesis Scale | Amino Acid Costs | HPLC Purification Costs | Expected Yield* |
|---|---|---|---|
| 0.1 mmol | $20/amino acid | $200 | ~150 mg Crude |
| ~5-20+ mg Purified | |||
| 0.25 mmol | $25/amino acid | $200 | ~150-200 mg Crude |
| (up to 8 amino acids) | ~10-50 mg Pure | ||
| 0.25 mmol | $34/amino acid | $200 | ~200-400 mg Crude |
| ~20-60+ mg Pure | |||
| plus left over crude |
*Peptide yields will depend on length and complexity of each sequence
Do you have a quote for a smaller scale synthesis? If so, send it to me so I can see if I can alter my normal synthesis scales to accommodate you.
"Ready-made and purified" peptides:
For those of you that only need a few mgs of peptide, we are offering some “ready-made and purified” peptides. The cost per mg is much lower than what you will find outside. If there is something we don’t have in stock that you would like us to make available, let us know.
