AnaSpec routinely completes difficult peptide synthesis such as synthesis of long peptides (>90-mers), peptides containing unusual modifications, and cyclic peptides. In addition, AnaSpec has the capacity for large-scale synthesis (>100 g).

Optimized Fmoc and Boc methodologies are employed for peptide syntheses. Cleavage of peptides is performed using trifluoroacetic acid (TFA), hydrogen fluoride (HF), or other appropriate methods. Most of the peptides are purified by HPLC using reverse phase C4 and C18 columns. Alternative purification methods (e.g., ion exchange and gel filtration chromatography) are used when needed. AnaSpec is equipped with state-of-the-art automated peptide synthesizers capable of performing synthesis ranging from small (0.025 mmol) to large (50 mmol) scale. These state-of-the-art synthesizers, coupled with our experienced peptide chemists, enable us to deliver our peptides quickly and in high quality (purity of 90-95% is typical). Most custom orders can be expected to be delivered in two to three weeks. Complete confidentiality of all orders is assured.

Because AnaSpec maintains its own facilities located in Fremont, CA, we are able to provide comprehensive oversight, to ensure we consistently meet our customer’s product specifications. AnaSpec is also proud to be Certified to ISO 9001:2008. All custom peptides are accompanied with MS and HPLC analyses. Additional analytical data (e.g., amino acid analysis, sequencing) are available upon request.
