Research buyers comparing PT-141 (10mg) SKUs should verify Cat No., purity targets, and lot records first—PT-141 Storage After Receipt covers Neuropeptide Research procurement.
PT-141, also known as Bremelanotide, is a melanocortin receptor agonist peptide used in laboratory research on melanocortin pathway signaling, receptor activation, and neuropeptide structure-activity studies.
PT-141 (bremelanotide) activates melanocortin MC3R and MC4R receptors studied in central nervous system slice preparations and receptor selectivity panels. Cyclic heptapeptide structure derived from melanotan scaffold research underpins receptor pharmacology studies.
MC4R cAMP assays, hypothalamic neuron calcium imaging, and receptor autoradiography map CNS melanocortin engagement in preclinical models. Melanocortin pharmacology literature distinguishes peripheral versus central receptor targets when interpreting peptide agonist selectivity profiles.
Shared -20°C storage needs project IDs on every box to avoid cross-contamination between peptide stocks. Receipt and storage: Inspect lyophilized cake and seal on arrival for PT-141. Label boxes with name, spec, lot, and receipt date.
Calculate reconstitution volume and aliquot count before opening the first PT-141 vial.
Storage guidance for PT-141: Store at -20°C, in a cool and dry place. On receipt, log lot number, date, and freezer shelf; plan aliquots before first reconstitution.
Document thaw count on each PT-141 aliquot; limit freeze–thaw cycles during multi-week assays.
Humidity during PT-141 reconstitution can affect peptide stability—work quickly in controlled conditions.
Receiving PT-141: inspect outer packaging, vial seal, and lyophilized cake appearance (White Lyophilized Powder). Photograph damage before opening claims with the carrier. Log lot number, receipt date, and responsible technician before moving material to -20°C storage. Freezer organization for PT-141 should segregate peptides by project ID on box labels—not product name alone. Shared Neuropeptide Research storage rooms accumulate dozens of similar vials; barcode internal IDs reduce mix-ups during busy assay weeks.
Reconstitution planning for PT-141 should be completed before the first vial is opened: target concentration, solvent type, aliquot volume, and tube count. Splitting planning across multiple sessions increases contamination and labeling errors. Thaw-count limits for PT-141 working aliquots should match your SOP (often three to five cycles). Exceeding limits without documentation undermines assay comparability when results drift across months-long studies.
Supplier storage text for PT-141 on sulanpeptide.vip is the baseline; your institution may require -80°C for long-term retention. Document any deviation from supplier guidance in the sample record with justification from stability literature.
