Genemed Synthesis Inc (GSI) has provided custom peptide synthesis for about 20-years. GSI has prepared >100,000 peptides for scientists all over the world. GSI products and services have been referenced in several hundreds peer reviewed publications. GSI peptide chemists can help you make peptides tailored to your specific requirements from mg to grams and purities approaching 98-100%.
GSI has prepared modified peptides that can be fluorescently labeled, biotinylated, phophorylated, acetylated, or have one or more disulfides (see available peptide modifications). We can also conjugate peptides to any carrier proteins for the purpose of making antibodies or couple them to Agarose to prepare affinity columns.
GSI has always offered high quality peptides at very competitive pricing. All peptides are verified by mass spectrometry and hplc. Additional quality controls such as amino acid sequencing and peptide content can be requested as well.
GSI has expanded its manufacturing capacity. We now offer even greater efficiency in terms of faster delivery and more cost savings. We are aware of the competitive pricing from other suppliers. We will also offer additional cost saving or al least match pricing from any US company.
GSI will be happy to advise you in the selection of antigenic peptides from gene/protein sequences at no cost if you were to order the peptides or antibodies from GSI.
If you need a custom peptide, please contact us with your needs and take advantage of our expertise. We will be happy to provide a cost estimates and turn around time. Use on-line price quote request form.
