OXM a 37 amino acid peptide which contains the glucagon sequence extended by a C-terminal basic octapeptide， its primary structure is identical in all mammals except in pig and cattle. OXM is released from the gut during digestion， together with glicentin another octapeptide containing molecule. It is considered as a putative physiological regulator of gastric acid secretion， it inhibits histamine.
Oxyntomodulin Human Recombinant produced in E.Coli is a single， non-glycosylated polypeptide chain containing 37 amino acids and having a molecular mass of 4420.86 Dalton.
The OXM is purified by proprietary chromatographic techniques.
Lyophilized Oxyntomodulin although stable at room temperature for 3 weeks， should be stored desiccated below -18℃. Upon reconstitution OXM should be stored at 4℃ between 2-7 days and for future use below -18℃.
For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）.
Please prevent freeze-thaw cycles.
