Custom Peptide Synthesis Service

Chempeptide offers custom peptides of the highest quality, at the most competitive price. Our staff has decade of intensive experience in the design, synthesis and production of peptides using Fmoc solid phase and solution phase technology. All peptides are purified using HPLC and analyzed by mass spectrometry and the reports will be provided to customers.

Every year over thousands of custom peptides are provided to worldwide customers,most custom peptides can be delivered within 2~3 weeks after receipt and confirmation of your order.

Custom Peptide Synthesis Quotation and Order information

Since custom peptide prices vary upon peptide length, purity and scale, we recommend submitting a quotation by email (info@chempeptide.com) for obtaining an accurate price.
 
The quoted price will depend on: 
1, The length of the peptide and the amino acid composition 
2, Unnatural amino acids, amino acid derivatives
3, Peptide modifications 
4, Required purity level e.g. crude, >70%, >75%, >80%, >85%, >90%, >95% or >98% on the basis of HPLC analysis 
5, Quantity:  from 1mg to kilogram scales.

In general the customer's request will be quoted within 2~12 hours.
 
For preparing a quotation we need some information about the peptides to be synthesized: 

1) Sequence of the amino acids 
2) N-terminus of the peptide (e.g. free or acetyl) 
3) C-terminus of the peptide (e.g. amide or carboxyl) 
4) Amount (e.g. 1mg, 5mg, 10 mg, 50 mg, 100 mg...) 
5) Purity (e.g. crude, >70%, >75%, >80%, >85%, >90%, >95% or >98%)
