Cyclotide Cycloviolacin O2 peptide (CyO2) is a cyclotide isolated from Viola odorata. Cyclotides are circular peptides with remarkable characteristics including a head-to-tail cyclized backbone and 6 cysteine residues forming cyclic-cystine-knot motif (CCK) by three disulfide bonds. Cyclotides show potent cytotoxic activity that’s why they represent novel range of cytotoxic agents. Cycloviolacin O2 peptide Cycloviolacin O2 has antitumor effect and specific membrane-disrupting activity resulting in cell death and appears to be selective to tumoral cells. CyO2 has also demonstrated a potent bactericidal activity against Gram – bacteria with a MIC of 2.2µM on E. coli. Cycloviolacin O2 provides a potential scaffold for future drug design. Cycloviolacin O2 peptide is a head-to-tail cyclic peptide with three disulfide bridges between 1-4, 2-5 and 3-6. SB-PEPTIDE is able to produce other cyclotides, including modified cyclotides with heavy isotope amino acids, biotin… Contact us to discu

Simian Parainfluenza Virus type 5 V5 peptide is an epitope peptide of Simian Parainfluenza Virus type 5 (SV5) belonging to the Paramyxovirus family. SV5 causes some common human diseases, such as pneumonia, bronchiolitis, measles and mumps. V5 peptide V5 peptide represents amino acids 95-108 of SV5 corresponding to RNA polymerase alpha subunit and non-structural protein V. V5 peptide sequence was chosen because high-affinity antibodies can be produced in many different species. V5 peptide is useful as tag for protein purification and detection such as Western blotting, ELISA assays, immunofluorescence, immunoprecipitation assays and for protein purification.

KD20 peptide is a lysine-aspartic acid peptide with 20 repeating units. KD20 peptide is used to stimulate CD4+ T cells in vitro and KD20 actions result in protection against abscesses induced by bacteria.

Neuropeptide: Neuropeptides are small signaling molecules produced and released by neurons engaged in many physiological functions. Indeed, neuropeptides act on neural substrates such as G protein-coupled receptors (GPCRs), tyrosine-kinase receptors, insuline-like peptides and also ion channels. Actions of Neuropeptides result in slow-onset, long-lasting modulation of synaptic transmission. FMRFamide: FMRFamide is a neuropeptide that is part of the family of FMRFamide-related peptides. Several FMRFamide-related peptides are involved in various cellular regulation and have shown pharmacological actions, such as anti-opiate effects. FMRFamide plays an important role in cardiac activity regulation in Hard clam.
