Custom Peptide Synthesis

AAPPTec supplies the highest quality custom peptide synthesis service at the most competitive prices for many years.

AAPPTec custom peptide synthesis has been very successful because our custom peptide synthesis chemists have over 25 years experience providing high quality custom peptide synthesis service. AAPPTec custom peptide synthesis is performed using our multiple peptide synthesizers for faster, high quality and economical custom peptide synthesis since these automated peptide synthesizers can produce 96 different peptides in a short time. We are dedicated to the research, development, manufacture and marketing of diverse peptides and custom peptide synthesis.

AAPPTec custom peptide synthesis service provides custom peptides from milligram research scale to multi-kilogram production scale. AAPPTec uses top quality peptide synthesis resins, reagents and state-of-the-art methods in all custom peptide synthesis to assure the highest yield and purity. Custom peptide synthesis of peptides containing unusual amino acids, modified side chains or other modifications is performed to the same high quality standards as standard peptides. All custom peptide synthesis products are provided with a complete quality control package including HPLC and Mass Spectral Analysis to confirm the purity and identity of the custom peptide. From 2 amino acids to 85 amino acids, AAPPTec can prepare custom peptides in the scale and purity required. We comply with the most stringent custom peptide synthesis quality control specifications for a reasonable price.

AAPPTec custom peptide synthesis chemists have the experience and expertise to prepare even long peptides in high purity. As an example of AAPPTec custom peptide synthesis experience, AAPPTec has synthesized and delivered 78 amino acid custom peptides at 95% purity.

 

AAPPTec custom peptide synthesis products are provided with the following purities:

  • Immunological Grade (suitable for forming polyclonal antibodies)
  • 80% or greater (tissue culture; ligand for affinity purification; non-quantitative antibody blocking experiments)
  • 90% or greater (in vivo studies; bioassays; markers for electrophoresis; monoclonal antibodies)
  • 95% or greater (ELISA; RIA; enzyme substrate)
  • 98% (NMR; chromatography standards)

 

AAPPTec custom peptide synthesis services include:

  • MAP Peptides
  • Cyclic Peptides
  • Peptides Containing Unusual Amino Acids
  • Peptides with Modified Side Chains
