Biological Activity
Metkephamid acetate is a synthetic opioid pentapeptide and derivative of (Met)enkephalin. It shows as a potent agonist of the delta- and u-opioid receptors with roughly equipotent affinity, and also has similarly high affinity as well as subtype-selectivity for the kappa3-opioid receptor.
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.
Use a bath-type ultrasonic cleaner at standard cleaning frequency (37–40 kHz). Bath sonication is gentler than a probe sonicator and avoids sample overheating. Sonicate in 5–10 second intervals, checking solubility between pulses, for no more than 2–3 minutes total. Warm the bath to 37 °C if solubility remains poor.
Generally, for molecules that require light-protected storage, we will ship them in amber glass bottles.
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
