HEPPSO
Based on 1 Customer Validation
HEPPSO is a zwitterionic Good's buffer suitable for physiological pH conditions. HEPPSO forms high-order oligomers in aqueous solutions and can form a 1:1 complex with Cu2+ via its hydroxyalkyl and tertiary amine groups. However, HEPPSO contains a structurally similar trace impurity lacking an alkanesulfonic acid side chain. The complex formed by this impurity and Cu2+ has a very low Ka; therefore, HEPPSO may interfere with studies on copper speciation analysis in natural water bodies.

生物活性
HEPPSO (35 mM) exhibits two copper binding behaviors in cell-free aqueous potentiometric titrations at pH 7.2 and 25 °C: direct weak binding with a log Kc of 2.05, and strong binding from a trace impurity with a log Kc of 7.68[2].
HEPPSO forms multiple self-associated oligomers, and no strong copper-binding impurity (like the m/z 131.1 species in HEPES) is detected in cell-free aqueous mass spectroscopy analysis[2].

溶剤 & 溶解度
H2O : 116.67 mg/mL (434.80 mM; Need ultrasonic)
DMSO : 100 mg/mL (372.68 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

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: ≥ 4.17 mg/mL (15.54 mM); Clear solution
This protocol yields a clear solution of ≥ 4.17 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (41.7 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: ≥ 4.17 mg/mL (15.54 mM); Clear solution
