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.

    Alyteserin-2c

    CAS:
    Alyerserin-2c is a C-terminally α-amidated 17 residue cationic anti-microbial peptide (AMP). Anti-microbial peptides (AMPs) are produced by the innate immune system and are expressed when the host is challenged by a pathogen. The Alyerserin family of peptides was first identified in norepinephrine-stimulated skin secretions of the midwife toad-Alytes obstetricans-(Alytidae). Alyteserin-2a, 2b and -2c show some sequence identity with bombinin H6, a peptide from the skins Bombinatoridae family of frogs.Alyteserin-2c is most potent against the Gram-positive bacteria-Staphylococcus aureus and has weak haemolytic activity against human erythrocytes.Alyteserin contain at least 50% hydrophobic amino acids. Hydrophobic residues contribute to the insertion of the peptide into the hydrophobic membrane core which results in membrane disruption and death of the pathogen. Due to their mechanism of action it is thought to be less likely for resistance to develop towards these peptides compared to conventional antibiotics.

  • Isotocin

    Isotocin

    Isotocin is a nonapeptide of the arginine vasopressin-oxytocin family produced exclusively in the preoptic area (POA) of teleosts. As a homologue of mammalian oxytocin, studying fish nonapeptides has shown that Isotocin mediates social and reproductive behaviour in fishes. Functional isotocin is stored in granules at the axon terminal with a carrier peptide, neurophysin. Stimuli leads to isotocin dissociation, to be released into the bloodstream or to cross over into the brain. It binds to G-protein coupled receptors (GPCRs), which subtype isotocin binds to defines the following physiological action. It, like other nonapeptides, is a neuromodulator in the CNS, but when distributed by the bloodstream, it acts as a peripheral hormone, such as regulating osmoregulation. Isotocin levels are sex-dependent and linked to the reproductive cycle.HPLC is a sensitive method to detect bioavailable isotocin and other nonapeptides. Measurement of mRNA levels of isotocin has been important to demonstrate the cyclical changes to regulate the endocrine calendar and diurnal rhythm. The level of isotocin is also considered a biomarker for aggression in behavioural indicators of fish welfare studies.

  • [5-TAMRA] Galanin, Human
    Biosynth

    [5-TAMRA] Galanin, Human

    Galanin is a neuropeptide synthesised and released by the brainstem locus coeruleus (LC). Galanin is expressed in most LC neurons in rodents and humans. Galanin has been shown to inhibit LC activity by hyperpolarising LC neurons, suppressing their spontaneous firing rate, and enhancing alpha2-adrenergic receptor-mediated negative feedback. Galanin is also a potent trophic and neuroprotective factor throughout the nervous system.Galanin is widely distributed in the central nervous, peripheral, and endocrine systems. Galanin's overarching function is as an inhibitory, hyper-polarizing neuromodulator for classical neurotransmitters like acetylcholine and serotonin. Galanin interacts with 3 receptor subtypes, GalR1-3 G protein-coupled receptors inserted into the plasma membrane. GalR1 is believed to activate a Gβγ pathway to regulate MAPK activation. GalR2 can also activate the MAPK pathway, but unlike GalR1, there is detectable inositol phosphate production. GalR3 is associated with the Galphai/o pathway. Activation of the receptor leads to a cellular influx of K+. Each receptor has been associated with neurological diseases such as GalR3 and epilepsy.Galanin protects against various physiological insults in vitro, including excitotoxicity and β-amyloid toxicity. Changes in galanin have been widely studied concerning Alzheimer's disease, and galaninergic neurons are spared in late-stage Alzheimer's relative to non-galaninergic neurones.Galanin is provided here with an N-terminal 5-TAMRA, a widely used red fluorescent reagent ideal for peptide labelling and detection. The excitation/emission for this reagent is 555 nm/580 nm. Cymit Quimica Laboratories Ltd is a custom peptide provider.
