EBV BZLF1 (40-48) (HLA-E)
EBV BZLF1 (40-48) (HLA-E) is an immunodominant CEF control peptide that is derived from the Epstein-Barr virus (EBV). EBV targets B cells, which can cause lytic infection and the consequent death of these cells. Natural killer (NK) cells, invariant (iNKT) cells, CD4T cells and CD8 T cells are essential to control the action of EBV-infected cells. EBV BZLF1 (40-48) (HLA-E) is defined as a CEF control peptide due to its antigenic properties. Clinically, these peptides are suitable epitopes for CD8+ T cells and can be used to stimulate the release of IFNg. HLA-E refers to the cell HLA type that this peptide acts on.The BZLF1 protein mediates the transition from the latent stage to the lytic stage of the virus's infection. The lytic stage of the γ herpesvirus has been found to be associated with human carcinogenesis and BZLF1's ability to activate p53 may allow it to induce DNA damage. Structurally it is similar to the leucine zipper family of transcriptional factors.Molecular weight:926.5 g/molH-EDSILAVR^-OH

Albumin (50-62) Bovine is derived from the globular protein Albumin and is found in the blood plasma of humans (known as Human Serum Albumin, HSA) where it serves to maintain plasma pressure and nutritional balance. Another role it carries out is the transportation of bound molecules through the blood. Bovine serum albumin (BSA), composed of 583 amino acids, is very similar to HSA thus allowing BSA to be used as a successful model and a standard protein in laboratory experiments.Although BSA and HAS share homology in their three domains, I, II and III, BSA contains 2 tryptophan whereas HAS only contains 1 tryptophan residue. In agriculture the presence of the albumin protein has been used to assess the health of cows to ensure that a suitable quality of milk and meat are produced. Moreover it is important to detect bovine albumin in food and pharmaceutical products due to it being an allergenic protein.In agriculture the presence of the albumin protein has been used to assess the health of cows to ensure that a suitable quality of milk and meat are produced.

Segment 18-39 of adrenocorticotropic hormone (ACTH). ACTH, also known as corticotropin, is a cleavage product from a larger precursor proopiomelanocortin (POMC). This 39 amino acid-peptide hormone is produced in the anterior pituitary gland upon stimulation by the corticotropin releasing hormone from the hypothalamus in response to stress. It stimulates the secretion of steroid hormone, specifically glucocorticoids in the adrenal cortex by acting through a cell membrane receptor (ACTH-R). In mammals, the action of ACTH is limited to those areas of the adrenal cortex in which the glucocorticoid hormones cortisol (hydrocortisone) and corticosterone are formed. ACTH has little control over the secretion of aldosterone, the other major steroid hormone from the adrenal cortex.Molecular weight:2,465.67 g/molAc-CKNTPDPDDLFSDI-OH

Acetyl-Claudin-3 is derived from the tight junction protein Claudin-3 which is encoded by the CLDN3 gene located on chromosome 7q11.23 and can be found within epithelial cell to cell contacts. Structurally, the Claudin family are transmembrane proteins containing two extracellular loops and are involved in maintaining cell polarity and controlling paracellular ion flux.During cancer research reduction in the number of Claudins has been associated with tumour formation. This could be explained using Claudin role in maintaining cell detachment and migration although cancers such as breast and prostate have shown to overexpress both Claudin- 3 and Claudin-4. Similarly in ovarian cancer overexpression of Claudin 3 and 4 is thought to increase the motility of tumour cells and their survival through basement membrane degrading matrix metalloproteinase activation.Both Claudin 3 and 4 have potential to be used as diagnostic markers and their two extracellular loops may be used as targets for antibodies. As receptors for the Clostridium perfringens enterotoxin, Claudin 3 and 4 may have further use in targeting the enterotoxin as a therapeutic for ovarian cancers.

Originally identified in Heloderma horridum horridum (Mexican beaded lizard), exendin-3 shares homology with vasoactive intestinal peptide (VIP), secretin, helospectin I and II and helodermin. Exendin-3 increases cellular cAMP levels and amylase release from pig pancreatic cells.Truncated exendin-3 is a potent and selective GLP-1 receptor antagonist. It inhibits cAMP production and insulin release induced by GLP-1, exendin-3, and exendin-4. It also blocks the inhibitory effect of GLP-1 on food intake in rats. Exendin 3 (9-39) amide is being considered for clinical use in obese patients. This is based on the extensive and consistent data demonstrating its effectiveness as a tool to improve fasting and postprandial levels of glucose and glucagon.

[Glp6,Pro9] Substance P (6-11)/Septide
Tachykinins are important neuropeptides throughout the nervous system involved in various roles including smooth muscle activity. Substance P is the natural ligand for neurokinin 1 (NK1) tachykinin receptor. Septide was originally identified from the C-terminus substance P and found to be a selective agonist of NK1 tachykinin receptor. Septide is a potent agonist able to stimulate muscle contraction in various models but not all. However, septide consistently lacks a high affinity for the NK1 tachykinin receptor compared to substance P or other applicable agonists. A 'septide sensitive' receptor is speculated, or it could be a conformation of NK1 tachykinin receptor. Further work is required to establish septide function and role in the nervous system. Septide is provided here with an N-terminal pyroglutamic acid to aid this investigation as is standardly used within the literature.Molecular weight:763.4 g/molH-LTILDQSEAPVR^-OH
