Below, those terms are addressed naturally through RUO-safe technical sections and FAQs (no medical claims).

What Is PT-141 (Bremelanotide)? Melanocortin Receptor Research Peptide

In research literature, bremelanotide (PT-141) is discussed as a melanocortin-pathway probe, often evaluated for activity across melanocortin receptor subtypes (commonly referenced in CNS signaling models). Researchers use PT-141 to explore receptor binding, cAMP signaling, and pathway-level modulation under defined experimental conditions.

PT-141 Mechanism of Action in MC4R / MC3R Signaling Models (Research Context)

PT-141 is widely referenced for melanocortin receptor pathway investigation, supporting assays that quantify receptor activation and downstream signaling readouts (e.g., cAMP-linked responses) in controlled in-vitro systems. Experimental design, receptor subtype selection, and endpoints are protocol-dependent.

PT-141 Research Applications: Receptor Binding, CNS Pathways, and Autonomic Readouts

  • Melanocortin receptor binding assays: receptor affinity/activation profiling in cell systems
  • MC4R pathway mapping: downstream signaling cascade exploration in mechanistic workflows
  • Neuroscience models: CNS-linked pathway studies focused on signaling and regulatory circuits
  • Comparative peptide research: contrast vs. other melanocortin-pathway peptides (protocol-dependent)
  • Analytical/QC workflows: identity/purity checks and reproducibility tracking in lab environments

PT-141 Storage and Handling: Lyophilized Peptide Powder + Reconstitution (RUO)

For pt-141 storage and preparation in RUO workflows, follow your laboratory SOP and the product documentation. Many labs store lyophilized peptides cold, protected from light and moisture, and prepare solutions only as needed for assays.

  • Lyophilized PT-141: store at −20°C or below, protected from light/moisture
  • After preparation: use within your protocol stability window (solvent/time are assay-dependent)
  • Best practice: aliquot where appropriate; avoid repeated freeze–thaw cycles

Why Researchers Choose Peptides Skin for PT-141 (Bremelanotide) RUO Supply

  • Verified purity: ≥99% HPLC verified (batch-based)
  • Identity support: MS testing and traceability practices
  • CoA availability: documentation for qualified research buyers
  • Secure shipping: packaging optimized for stability during transit

FAQs — PT-141 Peptide (Bremelanotide) Research Use Only

What is PT-141 peptide (bremelanotide) in research?

PT-141 (bremelanotide) is a melanocortin-pathway research peptide used in non-clinical workflows to study receptor signaling (e.g., MC4R/MC3R) and downstream mechanistic readouts in controlled systems.

Is PT-141 from Peptides Skin approved for human use?

No. Peptides Skin supplies PT-141 strictly as Research Use Only (RUO). It is not intended or approved for human or veterinary use, injection, or consumption.

What are the CAS number and molecular weight of PT-141?

Common references list CAS 189691-06-3 and a molecular weight of approximately ~1025.2 g/mol for bremelanotide (PT-141). Always verify against batch documentation for your laboratory records.

How should PT-141 lyophilized powder be stored?

Store lyophilized PT-141 at −20°C or below, protected from light and moisture. Follow your SOP and minimize freeze–thaw cycles to reduce experimental variability.

Do you provide PT-141 CoA and HPLC/MS data?

Yes. CoA is available upon request, with batch-based HPLC purity verification and MS identity support for qualified research customers.

A stark, brutish "Petulia" with a pistol in its pocket
It's about time this movie got released on DVD. It's odd that a film could spawn a remake ("Payback"), a glib nod ("Grosse Pointe Blank") and countless homages ("The Limey," among others) and still be as underseen as "Point Blank." The lack of a disc certainly didn't help its low profile, but of course this is a challenging, idiosyncratic movie, even three decades later. The plot is simple -- a crook is betrayed by his wife and partner and spends the rest of the movie trying to get what he's owed -- but the editing and narrative structure is unusual. What in the world did audiences possibly make of this back when it was first released? It's a remarkable film, as startling and innovative as Richard Lester's "Petulia," although admittedly it's thematically much less complex. This edition is excellent, too. Great sound, great picture and a fantastic commentary by director John Boorman and big-time "Point" fan Steven Soderbergh, who laughingly admits to Boorman that he's ripped this movie off more than a few times. Their chat is more technical than gossipy and deals heavily with the editing, the production (the script was only 70 pages long), the studio's concerns about the picture, the actors, violence, surrealism (is it all a dream?) and Boorman's elaborate use of color (the tones of clothing and sets intensify over the course of the film). I've gotten a lot of good DVD's this year but in terms of content, presentation and extas, this is one of the best.

One of Marvins better offerings
Like the Killers before marvin was almost destined to play the part of Walker in this fast moving gut wrenching but always realistic thriller brilliantly collaborated by Marvin and Boorman who had no peer in this type of film.For those unenlightened souls who downplay Marvins career this was the one that to my mind surpassed most of his prior efforts with the exception of the Killers which was above par in all respects.Marvin was ahead of the pack in the 60s playing this type of hard nosed no nonsense gangster type, no other actor came close and type casted him to some extent in this type of role which unlike may actors became a positive in his career. Just to show his brilliance as an actor he gave us later comedy roles which produced more acting accolades than that material for which he was better known namely what we see in Point Blank.He carries the whole movie as did all the great actors of that era and many since which in itself is the hallmark of greatness. Marvin was a man who so perfectly personified the parts he was playing that often other actors looked wooden in comparison.He was one of the rare individuals who could take a small co starring role and end up being the star of the movie, no mean feat when you were up against the best in the business at that time and there were plenty in the 60 and 70s.To my mind Point Blank will always be a MARVIN film and this is not to downplay other good workmanlike performances in the film but it will always rank highly in Marvins body of work which is a cut above his contemporaries in the roles for which he was known and appreciated.As for the film it played out in fairly predictable fashion until the final scenes under the golden gate brige which gave a nice twist and left the viewer unsure whether Walker did in fact take his money or simply leave the scene of the set up empty handed. The obvious answer is that he waited till the coast was clear and took his money. It is hard to accept that he did otherwise.In retrospect a movie that stands up 40 odd years later and is just as watchable as it was in 67. No mean feat.

A forerunner to Dirty Harry and Lee Marvin shining...
If you liked "The Getaway" or "Dirty Harry", then meet their forerunner. "Point Blank" is explosive, fast-paced, and still the acting is there. Good acting that is. Lee Marvin is at his best. Angie Dickinson. in her strong performance, is as beautiful as ever. Keenan Wynn and Carroll O'Connor play their parts to the hilt and it truly shows. John Vernon (who was The Mayor in "Dirty Harry") plays a slimy type with diligence and very believable. Add the killing pace of the entire picture, and you have a hot item, as sharp and cutting as "Film Noir" can be. Yes, because this is still a "Film Noir", despite the fact that it was filmed in Color and in the mid-sixties. John Boorman ("Hell in the Pacific", "Deliverance" and "The Emerald Forest"), skillfully "color coded" the entire movie, bringing it from absolute colors at the beginning, to more red-tinted ones towards the end. The only difference from a true "Film Noir" is its fast-paced storyline, that would lead us to movies as I have mentioned above. Marvin's minimalistic acting, but forceful presence, is enough to fill every frame of the movie with tension, action and complete mayhem. Compare him in "The Dirty Dozen" and "The Big Red One" and you will see what I mean. A big plus was the release on DVD. An excellent transfer with a sharp picture resolution, a clearcut sound, make it a very enticing experience to watch it at home. This is not just a Highly Recommended title. It is simply a Must!
