Peptidi
I peptidi sono catene corte di amminoacidi legate da legami peptidici, che svolgono ruoli chiave come molecole biologiche importanti nei processi cellulari. Funzionano come ormoni, neurotrasmettitori e molecole di segnalazione, e sono ampiamente utilizzati in applicazioni terapeutiche e diagnostiche. I peptidi sono anche cruciali nella ricerca per lo studio delle interazioni proteiche, delle attività enzimatiche e dei percorsi di segnalazione cellulare. Presso CymitQuimica, offriamo una vasta selezione di peptidi di alta qualità per supportare le vostre esigenze di ricerca e sviluppo in biotecnologia e farmacologia.

Prodotto fuori produzioneAzido-dPEG®3-Amine
CAS:<p>Azido-dPEG®3-Amine is a PEG compound with two different functional groups (also known as heterobifunctional). Unlike homobifunctional PEG compounds (same functional group on both ends), this type of compounds are more versatile as have two different anchor points. Azido-dPEG®3-Amine is used as a linker and spacer to add a PEG moiety, via pegylation (a bioconjugation technique) to proteins, peptides, oligonucleotides, small molecules and nanoparticles.</p>Purezza:Min. 95%Peso molecolare:218.25 g/molNeurokinin A (Human, Porcine, Rat, Mouse)
<p>Neurokinin A is a peptide that is derived from the precursor protein, preprotachykinin A, and has been found to be an endogenous ligand for the NK-1 receptor. It is involved in a wide range of physiological processes such as neurotransmission and regulation of blood pressure. Neurokinin A has been shown to inhibit adenylate cyclase activity in guanethidine-sensitive tissues and ionophores-resistant cells. The effects of Neurokinin A are not due to its ability to bind to the NK-1 receptor but rather through other mechanisms. The amino acid sequence of this peptide was first determined by cloning methods in 1984 and it has since been used extensively as a tool for studying the function of this receptor. Neurokinin A also inhibits cell proliferation in glioma cells and has been shown to have an inhibitory effect on Ca2+ concentration during electrical nerve stimulation.</p>Formula:C50H80N14O14S•2CH3COOH•5H2OPurezza:Min. 95%Peso molecolare:1,343.48 g/mol
