Glucagon (1-29)-[Cys(Cy5)]
Glucagon (1-29)-[Cys(Cy5)] is derived from glucagon, which is a peptide hormone secreted by alpha cells located in the islet of Langerhans region of the pancreas. Glucagon is an essential catabolic hormone that is responsible for the regulation of blood glucose levels. Once released into the bloodstream, glucagon stimulates the production of hepatic glucose, which means it is considered to be a glucose-mobilizing agent. Excessive levels of glucagon can result in the development of hyperglycaemia, since the action of glucagon results in abnormally high blood glucose levels.This peptide contains Cyanine 5 (Cy5), which is a widely used red fluorescent dye.Peso molecular:4,189 g/molAc-KVPRNQDWL-OH

H-Glu(Leu-OH)-OH
CAS:H-Glu(Leu-OH)-OH is a postprandial plasma metabolite that is produced by the hydrolysis of proteins and peptides. The profile of H-Glu(Leu-OH)-OH in plasma can be used to characterize the metabolism of these compounds and has been found to be useful for the diagnosis of metabolic disorders. H-Glu(Leu-OH)-OH levels are increased in patients with metabolic syndrome, obesity, diabetes mellitus type 2, chronic kidney disease, and cancer. This metabolite can also be used as an indicator for bacterial enzyme activity in the gut. H-Glu(Leu-OH)-OH levels are correlated with glutamate and sodium hydroxide solution levels in plasma or urine samples. H-Glu(Leu-OH)-OH may play a role in the pathogenesis of cancer due to its ability to inhibit DNA synthesis and protein synthesis.Fórmula:C11H20N2O5Pureza:Min. 95 Area-%Cor e Forma:PowderPeso molecular:260.29 g/molInfliximab Heavy chain (46-60)
Infliximab is a biologic medicine used in the treatment of numerous autoimmune diseases including Crohn disease, rheumatoid arthritis, and ankylosing spondylitis.

Flagellin is the structural protein which forms the major portion of bacterial flagella filaments. The N- and C- terminals of flagellin are highly conserved regions, whereas the central core can vary greatly between bacterial species. Flagellin 22 (flg22) is the most conserved stretch of amino acids across bacterial species and is located towards the N-terminal of flagellin.Flg22 is a potent elicitor of plant immune responses and is recognised in plants by the membrane bound leucine-rich repeat-receptor kinase FLAGELLIN SENSITIVE 2 (FLS2). Flg22 induces defence gene expression to trigger both local and systemic immune responses and is thus widely used in plant defence studies.Truncated flagellin 22 (flg22-θ”2) represents amino acids 1-20 of flg22.

JAG-1, scrambled
Scrambled peptide of JAG-1(188-204). Jagged - 1 is a cell surface ligand for in the Notch pathway. Notch receptors and ligands are present on the extracellular service of cells and require cell-cell contact for engagement. Ligand binding to Notch receptors results in the proteolytic cleavage of membrane-bound Notch receptors, thus allowing the intercellular region to be transported to the nucleus and become a transcriptional activator. The ligand-induced Notch activation is regulated by E3 ubiquitin ligases, Mindbomb1 (Mib-1) and Neuralized.JAG1 is widely expressed throughout mammalian development, across many tissues and developmental stages. Notch signalling plays a critical role in cellular fate determination including muscle cell differentiation, neurogenesis, and the development of the sensory regions of the inner ear- heart- kidney- eye- lung and other tissues.Jag-1 has been implicated in breast- cervical- colorectal- endometrial- gastric- head and neck- ovarian- hepatocellular- lung- pancreatic- prostate, and kidney and adrenocortical cancers, leukemia and lymphoma. Co-overexpression of Notch-1 and Jagged-1 predicts the poorest overall cancer survival. JAG1 mutations have also been associated Alagille syndrome.Peso molecular:2,105.9 g/molZ-Ile-Ser-OH

1,2-Dimyristoyl-rac-glycerol
CAS:1,2-Dimyristoyl-rac-glycerol (1,2-DMG) is a monomolecular fatty acid that has been found to inhibit the replication of herpes simplex virus. It binds to the surface glycoprotein and inhibits the release of diacylglycerol from the lipid membrane. 1,2-DMG also inhibits the activity of acyl chain enzymes, which are necessary for the synthesis of fatty acids in trypanosomes. This inhibition prevents the growth and proliferation of lung fibroblasts and may be beneficial in treating cancer. The ionisation mass spectrum shows that 1,2-DMG has a molecular weight of 270 Da.

Boc-D-Tyr(Br-Z)-OH
CAS:Boc-D-Tyr(Br-Z)-OH is a sugar alcohol that has been shown to have anti-bacterial activity. It has been shown to inhibit the growth of dental plaque by inhibiting the synthesis of oligosaccharides, which are a major component of this type of biofilm. Boc-D-Tyr(Br-Z)-OH also inhibits transfer reactions in the bacterial cell wall, and is therefore able to prevent the formation of cell walls. This compound also has prebiotic properties, which may be due to its ability to stimulate insulin production. The enzyme responsible for Boc-D-Tyr(Br-Z)-OH synthesis is Tools for Peptide Synthesis (TPS). TPS catalyzes a chemical reaction that uses an acceptor molecule (e.g., ATP) and microbial metabolism as substrates. The product of this enzymatic reaction is fatty acids, which are then used in biosynthesis processes such as fatty acidFórmula:C22H24NO7BrPureza:Min. 95%Peso molecular:494.33 g/molMART-1 (26-35)
CAS:Native Melan-A (26-35) decapeptide derives from the melanocyte lineage-specific protein Melan-A/MART-1, which is expressed in almost 75-100% of primary and metastatic melanomas. The region 26-35 of Melan-A protein acts as an antigenic peptide that is recognized by CD8+ tumor-reactive cytolytic T lymphocytes (CTLs) for designing antigen-specific cancer vaccines1. It has been shown that CD8+ Melan-A-specific CTLs isolated from melanoma patients efficiently lyse the Melan-A-expressing HLA-A*0201+ melanoma cell line. However, CTLs preferentially recognize the Melan-A (26-35) peptide as compared with the Melan-A (27-35) peptide. Moreover, the Melan-A (26-35) A27L analog (ELAGIGILTV) has a higher binding affinity to HLA-A*0201 than the native Melan-A (26-35) peptide (EAAGIGILTV), and consequently displays more potent antigenicity and immunogenicity. It has been reported that the concentration of Melan-A (26-35) A27L analog required to obtain 50% of maximal antigenic activity (EC50) is 0.01nM, whereas that of the native Melan-A (26-35) peptide is 0.25nM1. Therefore, the relative activity of Melan-A (26-35) A27L analog is 25 fold higher than that of the native Melan-A (26-35) peptide. Furthermore, functional competition assay has shown that the concentration of Melan-A (26-35) A27L analog required to achieve 50% inhibition (IC50) of tumor lysis is 2nM, which is 10 fold lower than that of the native Melan-A (26-35) peptide. Regarding peptide stability in human serum, the half-lifes (t1/2) of the native Melan-A (26-35) peptide and the A27L analog are quite similar (45 and 40min, respectively) as measured by HPLC-ESI-MS, but much higher than that of the Melan-A (27-35) nonapeptide (5min).Fórmula:C42H74N10O14Cor e Forma:PowderPeso molecular:943.1 g/molH-DIVGAVLK^-OH
