Masse moléculaire :1,680 g/molHistone H3 (1-22) K4Me3-Biotin
Histone H3 (1-22) K4Me3 is derived from Histone 3 (H3) which is one of the four core histones (H2A, H2B, H3 and H4) fundamental in compacting eukaryotic DNA into the nucleosome. The nucleosome arises when 147 base pairs of DNA wrap around a H3-H4 tetramer and two H2A-H2B dimers, forming the histone octamer core. Both H4 and H3 are highly conserved and perform roles in binding to segments of DNA which enter and leave the nucleosome and in chromatin formation. Similar to the other core histone, H3 has a globular domain and a flexible N-terminal domain, 'histone tail' which can undergo modifications such as acetylation, methylation, phosphorylation and ubiquitination. Due to histones containing a large number of lysine and arginine residues they have a positive net charge which interacts in an electrostatic manner with the negatively charged phosphate groups in DNA. The transcriptional activation or silencing of the chromatin is controlled by ATP-dependent chromatin remodelling factors and histone modifying enzymes which target histone proteins. Both processes function to alter the positioning of the nucleosome, allowing the DNA it to be either available or inaccessible to the transcription machinery.Another modification process histones can undergo is biotinylation where the covalent attachment of a biotin molecule is catalysed by the enzyme biotinidase. This cleaves biocytin to generate a biotinyl-thiester intermediate. The biotinyl can then be transferred onto the histone lysine ɛ-amino group which in this case it is covalently attached to Histone 3. Overall the biotinylation sites identified in histone 3 are: K4, K9 and K18. The presence of biotinylated histones have been detected in human cells such as lymphocytes and lymphomas.Lysine 4 of H3 (1-22) has been tri-methylated.Masse moléculaire :2,851.7 g/molRFRP-1 (Human)
CAS :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 receptor, insuline-like peptides and also ion channels. Actions of neuropeptides result in slow-onset, long-lasting modulation of synaptic transmission. Pro-FMRFamide-related neuropeptide VF: Pro-FMRFamide-related neuropeptide VF also called neuropeptide VF precursor are expressed in neurons in mediobasal hypothalamus. Neuropeptide VF precursor is a propeptide which is cleaved in three others peptide: Neuropeptide RFRP-1, RFRP-2 and RFRP-3. Neuropeptide RFRP-1 (81-92): Neuropeptide RFRP-1 play a role in the negative regulation of gonadotropin synthesis and secretion. Neuropeptide RFRP-1 is an agonist of the NPFF1 and NPFF2 receptors. In rats, Neuropeptide RFRP-1 increases prolactin release. Neuropeptide RFRP-1 (81-92) MPHSFANLPLRF-NH2 is a part of Neuropeptide RFRP-1 and is used to study NPFF receptors.Formule :C67H101N19O14SMasse moléculaire :1,428.73 g/molH-AGALNSNDAFVLK^-OH

[5-FAM]-Galanin (2-30)-[Cys] (Human)
Galanin is predominantly an inhibitory neuropeptide expressed in humans and other mammals' brains, spinal cords, and gut. Galanin signalling occurs through three G protein-coupled receptors. The functional role of galanin remains largely unknown- however, galanin is predominantly involved in the modulation and inhibition of neuron action potentials. Galanin has been implicated in many biologically diverse functions, including nociception, waking and sleep regulation, cognition, feeding, mood regulation and blood pressure regulation. Galanin appears to have neuroprotective activity as its biosynthesis is increased 2-10 fold upon axotomy and during seizure activity in peripheral tissues and the brain.The clinical relevance of galanin is related to several chronic neural disorders, including Alzheimer's disease, epilepsy, depression and cancer those who suffer from type 2 diabetes mellitus, depression and Alzheimer's disease often express high levels of galanin. Conversely, intervention with galanin agonists (for example, M617, M1145 and M1153) manifests anti-insulin resistance and anti-Alzheimer's disease characteristics and ameliorates or reinforces depression-like behaviour. Specifically, activation of GAL2 can alleviate such disease features in human and rodent models. This galanin (2-30) peptide has been used to characterise Galanin's binding sites and affinity for GALR receptors via competition binding analysis. Galanin (2-30) is a full agonist of the GALR2 receptor compared to its affinity for GALR1.Galanin (2-30) is provided with an N-terminal 5-FAM, a widely used green fluorescent reagent ideal for peptide labelling and detection and a C-terminal cysteine for site-specific conjugation. The excitation/emission for this reagent is 490 nm/520 nm.Couleur et forme :PowderMasse moléculaire :3,558.6 g/molAsp-Glu-Pro-Pro-Gln-Ser-Pro-Trp-Asp-Arg

This peptide represents the reserve sequence of β-amyloid 25-35 (Aβ 25-35) and is used as an inactive control peptide.Aβ has been identified as the key subunit of the extracellular plaques found in the brains of patients with Alzheimer disease (AD) and Down syndrome (DS). Aβ has therefore been extensively studied as a potential target for treatment of AD.Aβ is formed from the cleavage of the large, transmembrane protein- APP (amyloid precursor protein). Cleavage of APP by β- and then γ-secretases results in the formation of Aβ. Aβ can aggregate to produce amyloid-β oligomers, which are thought to be highly neurotoxic. Over time Aβ can further aggregate to produce the characteristic senile plaques present in AD and DS. Aβ can be degraded by enzymes such as neprilysin, insulin degrading enzyme or endothelin converting enzyme. At physiological levels Aβ may be involved in controlling synaptic activity and neuronal survival.

Formule :C40H64N14O12SDegré de pureté :Min. 95%Masse moléculaire :965.11 g/molSetmelanotide
Pro-opiomelanocortin (POMC)-derived peptides act on neurons expressing the Melanocortin 4 receptor (MC4R) to reduce body weight. Setmelanotide is a highly potent MC4R agonist that leads to weight loss in diet-induced obese animals and obese individuals with complete POMC deficiency.The endogenous ligand alpha-melanocyte-stimulating hormone (alpha-MSH) for MC4R has been shown to have a much lower affinity than Setmelanotide, explaining some of the drug's potency. Administration of Setmelanotide to wildtype mice resulted in significant weight loss while MC4R knockout mice fail to respond. Setmelanotide is in numerous clinical trials and shows promising results. Patients with POMC defects upstream of MC4R show more significant responses to treatment than those with MC4R deficiency or obese controls.Masse moléculaire :1,117.34 g/molAc-LGRI-NH2
