Peptide Synthesis Service Company Profile

Celtek Peptides

Celtek Peptides offers custom peptides of the highest quality. State-of-the-art peptide synthesizers, HPLC, and mass spectrometry instruments are utilized for these services. In terms of chemistry, advanced peptide methodologies are employed by us for peptide syntheses. Peptides are purified by HPLC using reverse phase columns. Other purification methods are also available if needed.

Featured Products • Peptides with different purities: desalted, >70%, >80%, >90%, >95%, or >98% • Peptides with different quantities: mg, g, or kg scale upon request • GMP-standard production and catalog peptides • Large peptides: up to 80 amino acids • Modified peptides: such as those with unusual amino acids, phosphorylation, biotinylation, terminal modifications and cyclization • Specially designed peptides: design and synthesis of specific bio-active peptides, such as enzyme inhibitors, antigenic peptides, and various cell-penetrating peptides useful for both in vitro and in vivo functional and therapeutic studies

All custom peptides are accompanied by a free synthesis report, HPLC and mass spectrometry analyses. Additional analytical data, such as amino acid sequencing and/or analysis can be provided upon request for an additional charge. All peptides will be shipped lyophilized free of charge.
