Colivelin (TFA) is a neuroprotective peptide and activator of STAT3. STAT3 Amyloid-β
Colivelin (TFA) is a hybrid peptide composed of ADNF and AGA-(C8R)HNG17, a potent Humanin (HN) derivative[2]. Humanin (HN) and its derivatives, such as Colivelin (TFA), suppress neuronal death induced by insults related to Alzheimer's disease (AD) by activating STAT3[1]. Colivelin (TFA) completely suppresses death induced by overexpressed FAD-causative genes and A 1-43 at a concentration of 100 fM, whereas AGA-(C8R)HNG17 does so at a concentration of 10 pM[2].
Humanin (HN) and its derivatives, such as Colivelin (TFA) also ameliorate functional memory impairment of mice induced by anticholinergic drugs or soluble toxic amyloid-β (Aβ)[1]. Intracerebroventricular administration of Colivelin (TFA) not only completely suppresses impairment in spatial working memory induced by repetitive intracerebroventricular injection of Aβ25-35 or Aβ1-42, but also it antagonizes neuronal loss in the CA1 region of hippocampus induced by hippocampal injection of Aβ1-42[2].

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

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 ddH2O, 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.
