ARF 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.Couleur et forme :PowderMasse moléculaire :1,867.1 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.Couleur et forme :PowderMasse moléculaire :1,888 g/molH5N1 Labeled 5-peptide Mixture

ANP 1-28 Human
ANP (1-28) 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 cardiovascular remodelling.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 pro-ANP (1-126) which is converted into the circulating forms by the type II transmembrane serine protease Corin.
Masse moléculaire :3,078.4 g/molH-Arg-Arg-AMC hydrochloride salt
CAS :H-Arg-Arg-AMC hydrochloride salt is a proteolytic inhibitor that binds to the active site of aminopeptidases and prevents their proteolytic activity. This inhibition leads to increased muscle mass in juveniles, as well as higher concentrations of magnesium ions in sarcoplasmic and myofibrillar proteins. H-Arg-Arg-AMC hydrochloride salt also has an inhibitory effect on ion exchange and chloride transport in muscle cells. The biochemical effects of this drug are due to its ability to inhibit the aminopeptidase enzymes, which play a role in the metabolism of amino acids.Formule :C22H33N9O4Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :487.56 g/molL17E
CAS :L17E is an endosomolytic peptide derived from the cationic and membrane-lytic spider venom peptide M-lycotoxin and contains a substitution of leucine by glutamic acid at position 17. L17E is able to promote the endocytic uptake and cytosolic delivery of exosome-encapsulated proteins.A major obstacles to intracellular targeting by antibodies is the limited release of the antibodies into the cytosol, once inside endosomes. L17E can achieve an enhanced cellular uptake via the induction of micropinocytosis. Once inside the endosome, positively charged L17E is able to preferentially disrupt negatively charged endosomal membranes to enable a marked cytosolic liberation of antibodies (immunoglobulins G (IgGs)) from endosomes.L17E had little pH dependence and no enhanced helical structure is needed for L17E-mediated membrane lysis.Formule :C134H219N37O32Couleur et forme :PowderMasse moléculaire :2,857.7 g/molPhosphatidylcholine-sterol acyltransferase [086-099]
