Peptides at Storkbio are synthesized within 1-2 weeks using Fmoc chemistry and purified by Reverse-Phase HPLC using columns C4 and C18. All peptides are analyzed by MALDI Mass Spectrometry to determine the molecular weight of the synthesized peptide and the presence of the desired product.
Peptides that meet the purity and mass requirements are then lyophilized, packed and shipped to the customer at room temperature by overnight dispatch.
Storkbio's standard peptide package includes a 5-30 L-amino acids long peptide, with purity 55-75% (crude) and amount of 20 mg and 100 mg or with purity over 95% and with amount of 5, 10, 15, 20, 25 and 50 mg. N-terminus has amine or acetyl, in C-terminus is free acid or amide. But of course, all other options are possible. Customer will get also HPLC and MS analysis data.
