SKU: ADRIA-PT141 Category: Tag:

PT-141, also known as bremelanotide in research literature, is a synthetic cyclic melanocortin peptide analogue. Laboratory literature discusses it in relation to central melanocortin receptor signalling, MC3R/MC4R pathway models, receptor-selective peptide activity, and neuroendocrine research systems.

The product is supplied for analytical and laboratory research contexts only. Description, categorisation, and customer-facing communication should avoid any therapeutic, body-use, veterinary, cosmetic, or outcome-focused language.

This product is supplied strictly for lawful research, laboratory, analytical, educational, or R&D purposes where permitted by applicable law. It is not intended for human or animal use.

Storage of Lyophilized Peptides

Upon receiving the lyophilized peptide, store it at 4 °C or colder and away from bright light. Lyophilized peptides are stable at room temperature for weeks, but for longer-term storage, it is safer to store them at -20 °C or colder. Exposure to moisture can greatly decrease long-term stability. Before opening a container stored in cold conditions, allow it to equilibrate to room temperature first to reduce moisture uptake from the surrounding atmosphere.

Peptides in Transport

Peptides in lyophilized form are supplied in glass vials by standard shipping methods and do not require refrigeration. Short-term temperature fluctuations during transport do not reduce their quality or stability. Even at high summer temperatures, peptides in lyophilized form remain stable for several weeks.

Storage of Peptide Solutions

The shelf life of peptide solutions is limited. Freezing aliquots can help prolong storage life. In general, peptide solutions are commonly stored for around 3 or more weeks at +4 °C and around 3-4 months at -20 °C. Avoid repeated freeze-thaw cycles, as this can degrade peptides.

Research use only. For lawful laboratory research and analytical use where permitted by law. Not for human or animal use.
