AAPPTec chemists have been performing custom peptide synthesis for over 25 years. Although AAPPTec is best known for automated peptide synthesizers, we are also a full custom peptide synthesis company. We have supplied 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)

Custom Peptide Synthesis Testimonial
"AAPPTec combines exceptional quality and characterization with extremely competitive pricing, and they often deliver peptides even more pure than we requested. I strongly recommend their custom synthesis service to colleagues who don't have the time, expertise, or equipment to make and characterize their own peptides."
-A Researcher from University of Pennsylvania

Large Scale Production
AAPPTec can perform custom peptide synthesis in larger scale, from gram to multi-kilogram quantities. AAPPTec complies with the most stringent quality control specifications at a competitive price. Let our experienced chemists assist with your development and production needs. All requests are evaluated with strict confidentiality.

For our profound experience in custom peptide synthesis, well-trained technical team and highest production standards, we hope to be your strong and reliable partner in the life sciences industry.

Custom Peptide Library Synthesis
AAPPTec custom peptide synthesis services can provide custom peptide libraries for epitope mapping, high-throughput screening and SAR studies, including alanine scans and truncation sets. Peptide libraries are provided in 96-well plates with approximately 2 µmol of lyophilized peptide in each well.

AAPPTec utilizes optimized protocols and chemistries in custom peptide synthesis to ensure consistent purity, quantity and quality, batch-to-batch and within each batch.

Custom peptide library modifications include D-amino acids, unusual amino acids, biotin or fluorescent labeling, N-acylation or C-terminal amide.

Provide AAPPTec with the peptide sequences and we will prepare a quotation for your library. Custom peptide synthesis of peptide libraries typically is completed in 2-3 weeks. Typical delivery consists of lyophilized peptides in 96-well titer plates, peptide location table, and MS and HPLC data.
