Peptides

Peptides are short chains of amino acids linked by peptide bonds, serving as important biological molecules that play key roles in cellular processes. They function as hormones, neurotransmitters, and signaling molecules, and are widely used in therapeutic and diagnostic applications. Peptides are also crucial in research for studying protein interactions, enzyme activities, and cell signaling pathways. At CymitQuimica, we provide a diverse selection of high-quality peptides to support your research and development needs in biotechnology and pharmaceuticals.

  • MART-1 (26-35) (human)

    CAS:
    Native Melan-A (26-35) decapeptide derives from the melanocyte lineage-specific protein Melan-A/MART-1, which is expressed in almost 75-100% of primary and metastatic melanomas. The region 26-35 of Melan-A protein acts as an antigenic peptide that is recognized by CD8+ tumor-reactive cytolytic T lymphocytes (CTLs) for designing antigen-specific cancer vaccines1. It has been shown that CD8+ Melan-A-specific CTLs isolated from melanoma patients efficiently lyse the Melan-A-expressing HLA-A*0201+ melanoma cell line. However, CTLs preferentially recognize the Melan-A (26-35) peptide as compared with the Melan-A (27-35) peptide. Moreover, the Melan-A (26-35) A27L analog (ELAGIGILTV) has a higher binding affinity to HLA-A*0201 than the native Melan-A (26-35) peptide (EAAGIGILTV), and consequently displays more potent antigenicity and immunogenicity. It has been reported that the concentration of Melan-A (26-35) A27L analog required to obtain 50% of maximal antigenic activity (EC50) is 0.01nM, whereas that of the native Melan-A (26-35) peptide is 0.25nM1. Therefore, the relative activity of Melan-A (26-35) A27L analog is 25 fold higher than that of the native Melan-A (26-35) peptide. Furthermore, functional competition assay has shown that the concentration of Melan-A (26-35) A27L analog required to achieve 50% inhibition (IC50) of tumor lysis is 2nM, which is 10 fold lower than that of the native Melan-A (26-35) peptide. Regarding peptide stability in human serum, the half-lifes (t1/2) of the native Melan-A (26-35) peptide and the A27L analog are quite similar (45 and 40min, respectively) as measured by HPLC-ESI-MS, but much higher than that of the Melan-A (27-35) nonapeptide (5min).

  • PLP (139-151)

    CAS:
    PLP (139-151) peptide is a fragment of myelin proteolipid protein (PLP or lipophilin), from amino acid residue 139 to 151 (HCLGKWLGHPDKF – CAS 131334-43-5 ). Myelin proteolipid protein is the major myelin protein from the central nervous system. PLP (139-151) peptide is commonly used to induce experimental autoimmune encephalomyelitis (EAE) in SJL/J mice. The PLP (139-151) peptide C140S is mutant of the wild-type version where the cystein is replaced by a serine to make the peptide more stable without impacting its antigenic activity.
