Melanocyte Protein PMEL 17 (256-264) (human, bovine, mouse)

Melanocyte Protein PMEL 17 (256-264) (human, bovine, mouse) is a synthetic peptide fragment corresponding to the conserved immunodominant epitope of the PMEL17/gp100 protein, a melanocyte differentiation antigen expressed in melanoma cells. This research-grade reagent is available as a lyophilized powder with high purity and is specifically designed for immunological studies, particularly in cancer immunotherapy research. The peptide sequence (KVPRNQDWL) is identical across human, bovine, and mouse species, making it a versatile tool for cross-species comparative studies and translational research applications in both academic and pharmaceutical settings.

TECHNICAL SPECIFICATIONS

Item	Specification
Product Name	Melanocyte Protein PMEL 17 (256-264) (human, bovine, mouse)
CAS NO.	/
Appearance	White to off-white lyophilized powder
Molecular Formula	C44H67N9O14
Molecular Weight	946.08g/mol
Purity (RP-HPLC)	≥ 95.0%
Solubility	It is readily soluble in water, physiological saline, or PBS buffer. It is recommended to prepare a stock solution of 1-10 mg/mL using sterile water or PBS, aliquot, and store at ≤-20°C. It is also soluble in a small amount of DMSO (<1%), followed="" by="" dilution="" with="" experimental="" buffer.="">
Endotoxin	< 1.0 EU/mg
Biological Activity	This peptide is an immunodominant epitope of the melanoma-associated antigen PMEL17/gp100 and can be recognized by HLA-A*0201-restricted cytotoxic T lymphocytes. In in vitro experiments, it effectively stimulates the proliferation and cytokine secretion of antigen-specific CTLs and is often used to assess anti-tumor immune responses. Specific activity needs to be verified through T cell activation assays.
Storage Conditions	Store at -20°C or lower in a dry environment away from light; it is stable for a long time. After reconstitution: Aliquot and freeze at ≤-20°C or -80°C, avoiding repeated freeze-thaw cycles.
Stock Location	Stock in USA
MOQ	1g

1.MECHANISM OF ACTION

The mechanism of action of this peptide involves its presentation by HLA-A0201 molecules on antigen-presenting cells, where it is recognized by specific CD8+ cytotoxic T lymphocytes (CTLs) through their T-cell receptors. This peptide-MHC class I complex engagement triggers CTL activation, proliferation, and the release of cytotoxic molecules such as perforin and granzymes, leading to the targeted lysis of antigen-expressing cells. The high-affinity binding of this epitope to HLA-A0201 and its efficient processing and presentation make it a potent immunogen for eliciting antigen-specific T-cell responses, which is the basis for its use in cancer vaccine development and adoptive T-cell therapy research.

2.PRODUCT INDICATIONS

This PMEL17 peptide is indicated for research use only in the fields of tumor immunology, cancer immunotherapy, and melanoma research. It is specifically employed as an antigenic stimulus in studies investigating T-cell responses, epitope mapping, and the development of cancer vaccines and adoptive cell therapies. The product serves as a standard reagent for characterizing antigen-specific CTL responses, validating diagnostic assays, and evaluating the efficacy of immunotherapeutic approaches in preclinical models. It is also used in cell-based assays to study antigen presentation, T-cell activation, and immune monitoring in both in vitro and in vivo settings.

3.CLINICAL EFFICACY OF PRODUCT

As a research reagent, Melanocyte Protein PMEL 17 (256-264) does not have established clinical efficacy for therapeutic use in human patients. Its utility is confined to preclinical research applications, where it has been used to study melanoma immunology and develop experimental immunotherapeutic strategies. While research using this peptide has contributed to the understanding of tumor antigen-specific immune responses and has facilitated the development of clinical-stage cancer immunotherapies, the product itself has not been evaluated in clinical trials for safety or efficacy. Any potential clinical applications derived from research findings would require separate development of therapeutic products that undergo rigorous clinical testing and regulatory approval.
