Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
Melted ice packs are generally not a concern for solid powder compounds, as the short transit period at ambient temperature does not typically affect compound integrity or potency. Powder form is inherently more stable than solution form during temperature fluctuations. Upon receipt, transfer the compound to −20 °C immediately. If you observe color change, odor, or physical changes, contact BioHippo for quality investigation.
For normal mice, the concentration of DMSO should be kept below 10%. For nude mice, transgenic mice, or mice with weak tolerance, the concentration of DMSO should be kept below 2%. For inhibitors being used for the first time, it is recommended to perform a solvent-negative control experiment to confirm that the solvent has no nonspecific effects on the animals.
Need this compound in a format that drops straight into your assay? We can tailor formulation, chemistry, and documentation so your results stay consistent across runs and re-orders.
- Format options: solid or pre-dissolved solution (choose solvent), target concentration, aliquots, light/moisture-protected packaging
- Chemistry options: free base/acid vs salt forms, hydrate/solvate preference, stereoisomer control (single enantiomer or racemate), close analogs
- Add-on labels & handles: D/¹³C/¹⁵N isotopes (LC-MS/internal standards), azide/alkyne or other functional handles for conjugation
- QC & documentation: standard COA or enhanced analytical pack (HPLC/LC-MS/NMR), chiral purity, residual solvents, water content (KF), method-specific specs
- Scale & continuity: mg to gram scale, bulk pricing, lot reservation, repeat-order continuity
