Fórmula:C72H116N20O22SPeso molecular:1,645.9 g/molCLEAR-OX™ Resin
CLEAR-OXTM is a highly effective polymer-supported reagent for the formation of disulfide bonds. Developed by Peptides International, incorporated to the Cymit Quimica Group through vivitide, CLEAR-OXTM combines the power of solid phase chemistry with the versatility of solution-phase reactions. CLEAR resin, compatible with both aqueous and organic environments, is transformed to CLEAR-OX through attaching a lysine-preformed cyclic Ellman’s reagent (DTNB) to a CLEAR polymeric support. Since the mechanism is based on peptide capture, sensitive residues such as Tyr, Trp, and Met are not affected, leading to increased purity and yield. Single disulfide-bridged peptides with constrained amino acids have been successfully produced using CLEAR-OX with various ring sizes and lengths. Oxidations are performed at higher concentrations than solution methods, leading to reduced solvent use at scale. Furthermore, oxidations can be carried out immediately after cleavage with only two-fold CLEAR-OX excess to obtain satisfactory yields. There is also potential for recycling and automation.Pureza:Min. 95%Ac-Qpw-NH2

CAS:Atorvastatin acid is a pharmaceutical compound belonging to the class of statins, which is a synthetic derivative of fungal metabolites. It functions as an HMG-CoA reductase inhibitor, playing a critical role in the cholesterol biosynthesis pathway. By inhibiting this key enzyme, atorvastatin acid effectively reduces the conversion of HMG-CoA to mevalonate, a precursor of cholesterol, thus lowering overall cholesterol levels in the bloodstream.Fórmula:C33H35FN2O5Pureza:Min. 98 Area-%Cor e Forma:White PowderPeso molecular:558.64 g/molARF peptide
ARF peptide, is the alternative frame (ARF) tumour suppressor protein which is expressed on the occurrence of oncogenic stimuli. It functions to prevent abnormal cell proliferation through inhibiting the p53 ubiquitin ligase protein Mdm2 from degrading p53. This results in the increased stability of the p53 tumour suppressor causing G1 cell cycle arrest. Additionally mouse ARF proteins can localise E2F1 and c-Myc transcriptions factors to the nucleolus therefore they are no longer able to activate S-phase promoting target gene. Again this results in cell cycle arrest, ultimately preventing tumour cell growth. It is evident that if the expression of the ARF peptide is inhibited tumour formation is more likely to occur.Cor e Forma:PowderPeso molecular:1,867.1 g/molH-AQDFVQWL^MNT-OH

N-formylated PSMalpha2
Pathogenic Staphylococcus aureus strains produce N-formylmethionyl containing peptides. Peptides starting with an N-formylated methionyl group constitute a unique hallmark of bacterial as well as mitochondrial metabolism, and professional phagocytes of our innate immune system recognise this microbial/mitochondrial pattern as a danger signal that guides innate immune cells.All PSMα peptides have the same basic functions and promote virulence through effects on discrete neutrophil functions (i.e. chemotaxis) and by being cytotoxic at higher concentrations. PSMα2 and PSMα3 can both bind to FPR2 and trigger superoxide release in neutrophils at low nanomolar concentrations. In addition, at high nanomolar concentrations they display cytotoxicity selectively on apoptotic neutrophil membranes and this occurs in an FPR2 independent manner.Cor e Forma:PowderPeso molecular:2,304.4 g/molH-His-D-Trp-D-Lys-Trp-D-Phe-Lys-NH2

The synthetic canonical Flag sequence has been shown to be most effective with the Asp-Tyr-Lys-Xaa-Xaa-Asp motif triplicated for applications in protein analysis followed by the eight amino acids at the C-terminus of the classic FLAG sequence (Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys). Due to the hydrophilic nature of the peptide the Flag tag typically resides on the surface of the recombinant protein thus minimising any effects on the function or transport of the fusion protein. The tag can be used in conjunction with other tags such as HA or myc depending on the application. FLAG is an artificial antigen to which high affinity monoclonal antibodies have been raised, therefore allowing for highly effective protein purification by affinity chromatography as well as accurate localisation of FLAG tagged proteins within living cells, or Western blots. FLAG peptide can be used to effectively purify complexes with multiple proteins as its mild purification procedure tends not to disrupt such complexes. It can be used to obtain proteins of sufficient purity for x-ray crystallography. The 3 x Flag peptide provides powerful detection and purification of recombinant proteins that has been characterised in numerous applications including affinity chromatography, binding assays and structural analysis.Peso molecular:3,649.8 g/molKinetensin

Fórmula:C78H107N21O18Peso molecular:1,626.84 g/mol[5-FAM] Histone H3 (1-14) K4Me3
Histone H3 (1-14) 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 to change the positioning of the nucleosome, allowing the DNA it to be either available to the transcription machinery or inaccessible.The Histone H3 (1-14) lysine 4 has been trimethylated and contains 5-Carboxyfluorescein (5-FAM), a widely used green fluorescent tag.Cor e Forma:PowderPeso molecular:1,888 g/molBTN2A1 Blocking Peptide

ANP (7-23) is derived from the atrial natriuretic peptide (ANP) which is a cardiac hormone involved in maintaining cardio-renal homeostasis. This occurs through the activation of the guanylyl cyclase-coupled receptor, resulting in the increased concentration of cyclic guanylate monophosphate. Moreover its function in the processes of anti-proliferation and anti-angiogenesis allow it to take part in the cardiovascular remodelling process.ANP is a member of the natriuretic peptide family and it is encoded by the NPPA gene, located on chromosome 1. Once synthesized from the 151 amino acid pre-prohormone into its biologically active form, ANP is secreted by the atrial cardiomyocytes in the circulating forms: ANP (1-98) and ANP (99-126). This synthesis process involves the signal peptide being removed from the pre-prohormone resulting in proANP (1-126) which is converted into the circulating forms by the type II transmembrane serine protease Corin.Cor e Forma:PowderPeso molecular:1,724.8 g/molSomatostatin-28
CAS:Somatostatin-28 is the 28 amino acid isoform of somatostatin and has similar activity to the 14 amino acid isoform. While the 14 amino acid form mainly acts in the brain, somatostatin-28 mainly operates in the gastrointestinal tract. Somatostatin is a peptide hormone that is widely expressed throughout the body for example in the gastrointestinal (GI) tract, hypothalamus, pancreas and the central nervous system. It has been found to inhibit pituitary growth hormone release as well as endocrine, pancreatic and GI secretions. In the central nervous system somatostatin plays a role in neurotransmission modification and it has also demonstrated to be effective against a number of cancers such as squamous carcinoma.Fórmula:C137H207N41O39S3Pureza:Min. 95%Peso molecular:3,148.62 g/molE-64
CAS:E-64 is a chemical inhibitor that binds to the ATP synthase in mitochondria, inhibiting oxidative phosphorylation. This inhibition of mitochondrial energy production leads to cell death by apoptosis. E-64 has been shown to inhibit tumor growth in vitro and in vivo by inducing autophagy and inhibiting cancer cell proliferation. E-64 has also been shown to have proteolytic activity against serum proteins, which may be due to its ability to bind to the phosphate groups of proteins.Fórmula:C15H27N5O5H2OPureza:Min. 95%Peso molecular:366.42 g/molGLP-1 (1-37)
CAS:Glucagon-like peptide (GLP) 1 is a post-translationally modified version of proglucagon. GLP-1 (1-37) is a naturally produced analog of GLP-1. Unlike truncated GLP-1, GLP-1 (1-37) does not alter food intake in rat models or pancreatic insulin secretion. GLP-1 (1-37) can induce insulin production in developing adult intestinal cells via upregulation of the ngn3 gene and its downstream targets. This can restore glucose homeostasis when implanted into diabetic mice. GLP-1 (1-37) may offer a future treatment for diabetes mellitus. GLP-1 (1-37) can also inhibit chemokine-induced migration of human CD4-positive lymphocytes, an early step in atherogenesis. This raises the possibility that GLP-1 (1-37) is part of a novel mechanism to modulate vascular disease.Peso molecular:4,169.54 g/molHyp-Gly dipeptide
