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.

Setd8 is a member of the SET domain containing family of proteins and is the sole methyltransferase that catalyses monomethylation of lysine 20 on histone H4 (H4K20me1). This histone modification is involved in regulating DNA replication, chromosome condensation and gene expression.Setd8 is widely expressed and in addition to modifying histone H4, it can modify non-histone proteins, including p53. Setd8 has been shown to play a role in maintaining skin differentiation and is dysregulated in multiple cancer types.Molecular weight:1,076.7 g/molAcetyl-Histone H4 (1-21)
Histone 4 (H4) is one of the four core histones (H2A, H2B, H3 and H4) which are essential for compacting eukaryotic DNA into the nucleosome. Due to the high lysine and arginine content, histones have a net positive charge and therefore electrostatically interact with negatively charged DNA. 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. Like other core histones, H4 has a globular domain and a flexible N-terminal domain, the histone tail, which can undergo modifications such as acetylation, methylation, phosphorylation and ubiquitination.Gene transcriptional activation or inactivation is controlled by ATP-dependent chromatin remodelling factors and histone modifying enzymes. Both processes function to alter the positioning of the nucleosome, allowing the DNA within to be either accessible to the transcription machinery or inaccessible. H4 lysine rich tail plays a role in the higher order chromatin folding.Acetyl-Histone H4 (1-21)-has an uncharged C-terminal amide and is protected from N-terminal modifications by a covalently bonded acetyl group.Molecular weight:2,131.3 g/molPAR-4 Agonist (Mouse)
CAS:Thrombin is the main effector of the coagulation cascade- it is a serine protease. Thrombin binds to active protease activated receptor (PAR) which belongs to a subfamily of G-protein coupled receptors (GPCR). Thrombin activation of mouse PAR-4 reveals an amino terminus sequence of GYPGKF. This is the natural ligand for PAR-4. GYPGKF binds internally to the receptor and leads to signalling activation. Identification of GYPGKF as a PAR-4 agonist has allowed better understand of the function of PAR. Addition of GYPGKF to PAR-4 expressing cell lines achieved 55% of the maximal response of thrombin. GYPGKF can provide understanding of PAR-4 and a template for more potent agonists.

CAS:Custom research peptide; min purity 95%. For different specs please use the Peptide Quote ToolFormula:C54H78N16O10Molecular weight:1,111.32 g/molSpexin
Spexin is a neuropeptide that is conserved amongst humans and rodents. Spexin activates galanin2/3 receptors, inducing a different active conformation of GalR2 to galanin. The broad distribution of spexin suggests multiple physiological roles including as a regulating factor in obesity and energy metabolism. Spexin is ubiquitously expressed in human tissue, however, a correlation has been found with obesity and age. Obese patients had significantly lower levels of circulating spexin than those with a healthy weight range. The significance of this suggests spexin regulates appetite, feeding behaviour, and energy expenditure. Spexin also specifically inhibits the uptake of long-chain fatty acids by adipocytes.Spexin is a central modulator of cardiovascular and renal function and can elicit central nervous system behavioural responses. As spexin levels decrease with age there is research to understand if it plays a role in age-related pathophysiology of cardiometabolic conditions. Spexin is also being considered an early biomarker for cardiovascular disease due to the magnitude with which it decreases as the pathophysiology progresses.Molecular weight:1,618.8 g/molPolylysine

Custom research peptide; min purity 95%. For different specs please use the Peptide Quote ToolMolecular weight:1,777.1 g/molFibrinopeptide
Fibrinogen is a large plasma glycoprotein with a complex structure, and one of the most abundant proteins in blood. Fibrinogen is important in fibrin clot formation, haemostasis, and inflammatory responses. Increased plasma fibrinogen indicates a proinflammatory state and is a risk factor for vascular inflammatory diseases including hypertension and atherosclerosis. Fibrinogen cleavage products act as inflammatory activators in the pathophysiology of allergic asthma.The conversion of monomeric fibrinogen into polymeric fibrin is mediated by thrombin, which binds to fibrinogen and catalyses cleavage of fibrinopeptide A (FpA) and fibrinopeptide B (FpB). Fibrinopeptide B is protected from modifications such as carbamylation by pyroglutamination of the N-terminal amino acid.Color and Shape:PowderMolecular weight:1,551.7 g/molSakamototide
Sakamototide is phosphorylated by members of the 5'-adenosine monophosphate-activated protein kinase (AMPK) family of kinases as is therefore ideal for use in kinase assays to test the activity of AMPK family members. The AMPK family includes- salt inducible kinases (SIKs), NUAK's, sucrose non-fermenting (Snf1)-related kinase (SNRK), microtubule affinity regulating kinases (MARKs) and brain specific kinase/BR serine/threonine kinase (BRSK). The kinase activity of AMPK and AMPK-related kinases, is dependent on its phosphorylation at Thr175 by the upstream kinase LKB1 (also known as STK11).Color and Shape:PowderMolecular weight:1,738.9 g/molExendin 4 (4-39)
This is a truncated exendin-4 peptide, the original peptide was identified in Gila monster lizard (Heloderma suspectum). Exendin-4 is an incretin mimetic, an analog of glucagon-like-peptide-1 (GLP-1), it stimulates insulin secretion and modulates gastric emptying to slow the entry of ingested sugars into the bloodstream. Exendin-4 is resistant to cleavage by plasma DPP-IV unlike GLP-1. This gives it a longer half-life and duration of action than GLP-1, as well as greater potency in vivo. Exendin-4 increases insulin sensitivity and improves glucose tolerance and is currently used for the treatment of Type 2 diabetes mellitus in its synthetic form Exenatide.Exendin-4 also promotes the production and proliferation of β-cells leading to regeneration of the pancreas. It is a ligand to the exendin receptor and increases pancreatic acinar cell cAMP levels. However, the GLP-1 analog was found to have a toxic effect by inducing hypotension due to relaxation of the cardiac smooth muscle.Color and Shape:PowderMolecular weight:3,860.9 g/mol[FITC]-Ahx-(KKEEE)3K carrier peptide
The [FITC]-Ahx-(KKEEE)3K carrier peptide contains the fluorescent label fluorescein isothiocyanate (FITC), where the isothiocyanate can generate a stable thiourea linkage through reacting with the amine group present on protein molecules. The Ahx group (1,6-aminohexanoic acid) is used as a spacer to N-terminally link the FITC to the (KKEEE)3K carrier peptide. The (KKEEE)3K peptide sequence has shown significant specific renal targeting, thus giving it kidney-specific drug carrier properties. In particular its ability to target drugs to the proximal tubule cells of the kidney suggests potential to aid in the treatment of renal diseases.
