Melanotan II

$40.00

Melanotan Il is a synthetic analog of the melanocyte-stimulating hormone alpha-MSH.

It is widely studied in research models for its interactions with melanocortin receptors and its effects on pigmentation, appetite regulation, and sexual function.

It is commonly used in studies exploring melanocortin signaling pathways and metabolic regulation.

Melanotan Il is a potent research peptide valued for its activity at melancortin receptors and its impact on pigmentation and physiological regulation.

Melanotan II is a cyclic melanocortin analog used in RUO models to interrogate receptor-mediated signal transduction and cellular stress-response pathways. Studies often quantify MC-receptor engagement, downstream transcriptional effects, and redox-linked responses in vitro. Not intended for diagnostic or therapeutic use.

  • MC receptor engagement and bias profiling
  • Oxidative-stress response readouts
  • Signal kinetics and transcription mapping

Category Overview | Signal Transduction Pathways

Signal transduction peptides are used in RUO studies to explore how cells send and receive messages. These signals help control how cells grow, repair themselves, and respond to stress. Researchers use these peptides in lab models to better understand how communication inside cells works—and what happens when it doesn’t.

Exciting Areas of Study

  • How cellular signals initiate chain reactions in lab models.
  • Peptide effects on messaging pathways like MAPK & PI3K.
  • How cells respond to stress in lab models.
  • Model disrupted signaling seen in pre-clinical disease research.
  • Map how cell signals change under different conditions

Melanotan II | Research Modeling & Applications
  • Profile MC receptor bias and downstream readouts
  • Quantify ROS/antioxidant pathway responses
  • Benchmark transcriptional signatures under stress
