Ara h 2 is one of the major allergenic proteins from peanut (Arachis hypogaea) which contains approximately 13 potential allergenic proteins.Ara h 2 is a member of the 2S albumins (conglutinins) belonging to the prolamin superfamily which also includes Ara h 6. 2S albumins contain major food allergens from seeds of many mono- and dicotyledon plants and share a common compact structure that renders the proteins highly resistant to proteolysis.In mouse models Ara h 2 and Ara h 6 are the main cause of effector responses such as mast cell degranulation and anaphylaxis. Ara h 2 has a high predictive value for diagnosis of clinical peanut allergy and is also more potent than Ara h 1 or Ara h 3 in histamine release assays and skin prick tests.This peptide represents a tryptic peptide of Ara h 2.Color and Shape:PowderMolecular weight:1,027.5 g/molFALL-39
Custom research peptide; min purity 95%. For different specs please use the Peptide Quote ToolFormula:C217H354N62O55Molecular weight:24.7 g/molHistone H4 (1-23)
Histone 4 (H4) is one of the four core histones (H2A, H2B, H3 and H4) which are fundamental in 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's lysine rich tail plays a role in the higher order chromatin folding.Color and Shape:PowderMolecular weight:2,400.5 g/molAc-EEEEE-OH

The HIV gag gene encodes p17 and p24. P17 Gag is a matrix protein that is vital to HIV life cycle, it targets viral RNA to the nucleus and Gag polyproteins to the cell membrane- p17 Gag accumulates in the extracellular space of tissue while interacting with receptors on various cell types to deregulate cell function.During HIV infection the cytotoxic T lymphocyte (CTL) response is key to attenuating viral replication. CTL recognition epitope of p17 Gag is identified as residues 77-85 to activate the immune response. HIV p17 Gag CTL epitope has been used in IgG titres and has been suggested as a suitable prognostic tool for onset of AIDS. A high affinity of IgG for p17 Gag was correlated to patients remaining in an asymptomatic state. p17 Gag epitope has been shown to induce a strong CTL response in the majority of chronically infected HIV patients. This makes the p17 Gag epitope a target for molecular therapy for HIV treatment and potentially a vaccine development.Color and Shape:PowderMolecular weight:980.5 g/molH-ESHVTLASPEETR^-OH

Albumin is a family of globular, water soluble, un-glycosylated proteins commonly found in blood plasma. Albumins generally act as transport proteins that bind to various ligands to transport them around.The most common member of this family is serum albumin. Serum albumin is produced by the liver and is the most abundant plasma protein, it provides oncotic pressure, transports bilirubin, steroids, fatty acids, thyroid hormones and other hormones, and serves as an extracellular antioxidant agent.Too much or too little circulating serum albumin may be harmful. Perturbations in serum albumin concentration is associated with both type 2 diabetes and metabolic syndrome (MetS). Increase in serum albumin concentration might protect against early glycemic deterioration and progression to type 2 diabetes even in subjects without MetS. Albumin in the urine usually denotes the presence of kidney disease.Molecular weight:1,055.7 g/molH-SLSLSPG-NH2

Urumin
Urumin is a veridical host defence peptide against influenza A virus.The peptide specifically targets the evolutionarily conserved H1 hemagglutinin stalk region of H1-containing influenza A viruses.Urumin has been used against drug-resistant influenza A viruses that are resistant against oseltamivir, zanamivir and peramivir. While its mechanism of action is not fully understood, urumin seems to inhibit viral growth by physically destroying influenza A virions, and is able to protect naive mice from doses of influenza A infection as high as 2 times the LD50. Because of its specific targeting of the hemagglutinin stalk region of the influenza A virus, the mechanism of action of urumin is similar to that of antibodies induced in the body by universal influenza vaccines.Molecular weight:2,959.4 g/molHLA-A*02:01 HBV core (18-27)
HLA-A*02 is a class I major histocompatibility complex (MHC) allele which is part of the HLA-A group of human major histocompatibility complex (MHC) leukocyte antigens (HLA). HLA-A is a human MHC class I cell surface receptor and is involved in presenting short polypeptides to the immune system. These polypeptides are typically 7-11 amino acids in length and originate from proteins being expressed by the cell. Cytotoxic T cells in the blood "read" the peptide presented by the complex and should only bind to non-self peptides. If binding occurs, a series of events is initiated culminating in cell death via apoptosis. This peptide corresponds to the Hepatitis B variant (HBV) core sequence which is presented on the MHC class I antigen HLA-A*02.Molecular weight:1,154.6 g/molh-Chemerin-9 (149-157)
A Chemerin-9 peptide derived from chemerin, a protein that is involved in a variety of functions such as autocrine, angiogenic, reproductive and chemotactic processes.

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.

Spexin
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/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/molMelanocyte Associated Antigen gp 100 (17 - 25)

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/molH-FRKKWNKWALSR-NH2
