Humanin
Based on 1 Customer Validation
Humanin, an anti-apoptotic peptide of 24 amino acids, is a Bax inhibitor. Humanin prevents the translocation of Bax from cytosol to mitochondria, blocks Bax from the inactive to active conformation. Humanin is a mitochondria-associated peptide with a neuroprotective effect against AD-related neurotoxicity. Humanin also improves overall insulin sensitivity in animal. Humanin are related to aging.
Humanin analogue, in which the serine at position 14 is replaced by glycine, names HNG.

Biological Activity
Humanin analogue, in which the serine at position 14 is replaced by glycine, names HNG[2].

Bax |
Humanin (40 nM, rhodamine-conjugated; 30 min) inhibits cell death induced by Bax protein in wild-type HCT116 cells[1].
Humanin (100 μM; 10 min) blocks Bax association with isolated mitochondria, and suppresses cytochrome c release in wild-type HCT116 cells[1].
Humanin reduces half apoptosis induced by 0.2 mM STS[1].
Humanin fails to suppress apoptosis in Bax-deficient HCT116 cells[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 10 mg/mL (3.72 mM); Clear solution
This protocol yields a clear solution of ≥ 10 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (100.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 10 mg/mL (3.72 mM); Clear solution
This protocol yields a clear solution of ≥ 10 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (100.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
