|
(Glu⁸·⁹)-Helodermin has been isolated from the salivary gland of the Gila monster Heloderma suspectum. It consists of 35 amino acids and shares 53 and 42% homology with human pituitary adenylate cyclase activating polypeptide (PACAP) and vasoactive intestinal peptide (VIP), respectively. It was shown to have high affinity for the mammalian VIP₂ receptor and equal potency and efficacy for stimulating cAMP production compared with mammalian VIP and PACAP. Even a helodermin-preferring receptor has been described. Furthermore, immunohistochemical studies, using antibodies that did not cross-react with mammalian VIP or PACAP or other known members of the GLP-1 / VIP / PACAP peptide family suggested the existence of a mammalian homologue to (Glu⁸·⁹)-Helodermin distinct from VIP and PACAP.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
