[Rhodamine Green]-LifeAct (Abp140 1-17)
[Rhodamine Green]-LifeAct (Abp140 1-17) contains the 17amino acid peptide Lifeact derived from amino acids 1-17 of the Saccharomyces cerevisiae actin binding protein, Abp140. These first 17 amino acids of Abp140 are crucial in allowing Lifeact to localise to actin filaments (F-actin) and therefore it can be used as a cytoskeletal marker. On application, lifeact can be used in the study of plant development and pathogen defence as filamentous actin within the plant actin cytoskeleton is important in key processes such as cell division, membrane trafficking and stomatal movements.The addition of the Rhodamine Green fluorophore, Rhodamine Green allows the location of the LifeAct (Abp140 1-17) to be detected.Peso molecolare:2,279.1 g/molH-ITQSNAILR^-OH

Biotinylated aMp3 is a Mycobacterium avium subsp. Paratuberculosis (MAP) specific ligand. MAP can cause Johne disease (the wasting disease) in livestock. It is important therefore to detect the presence of MAP in animal milk and faeces.Biotinylated aMp3 can be used (along with aMptD peptides) to detect the viability of MAP cells in infected livestock through combined peptide-mediated magnetic separation phage display due to their high affinity for MAP. The addition of biotin to aMp3 asparagine residue, changes the orientation of aMp3 so that it can bind to the target bacteria with increased stability, thus achieving a high capture efficiency. A similar effect is observed on the addition of biotin to aMptD glycine residue.Peso molecolare:1,642.8 g/molTau Peptide (306-317) trifluoroacetate salt

Aβ has been identified as the key subunit of the extracellular plaques found in the brains of patients with Alzheimer's disease (AD) and Down's syndrome (DS). Aβ has therefore been extensively studied as a potential target for treatment of AD.Aβ is formed from the cleavage of the large, transmembrane protein- APP (amyloid precursor protein). Cleavage of APP by β- and then γ-secretases results in the formation of Aβ. Aβ can aggregate to produce amyloid-β oligomers, which are thought to be highly neurotoxic. Over time Aβ can further aggregate to produce the characteristic senile plaques present in AD and DS. Aβ can be degraded by enzymes such as neprilysin, insulin degrading enzyme or endothelin converting enzyme. At physiological levels Aβ may be involved in controlling synaptic activity and neuronal survival.Colore e forma:PowderPeso molecolare:1,153.6 g/molH-DSLYLQMNSLR^-OH

[5-FAM]-GLP-1 (7-36)
The native form of GLP-1 in humans is the GLP-1 (7-36) amide. GLP-1 (7-36) amide is highly unstable (half-life <-2 minutes) due to proteolytic degradation by the serine protease- dipeptidyl peptidase-IV (DPP-IV). DPP-IV cleaves the N-terminal histidine and alanine residues from GLP-1 to generate two equipotent forms: GLP-1 (9-37) and GLP-1 (9-36) amide. This degradation mitigates against the therapeutic use of GLP-1 itself, therefore DPP-IV-resistant peptide analogues have been developed and licensed for clinical useThis peptide contains N-terminal 5-Carboxyfluorescein (5-FAM), a widely used green fluorescent tag

Nef is an accessory protein highly conserved amongst all primate lentiviruses, it is essential for viral replication in vivo- it is expressed by human immunodeficiency virus (HIV) HIV-1 and HIV-2. Nef acts as a downregulator of class I human leukocyte antigens (HLA) expression in HIV-infected cells to help circumvent the immune response, such as cytotoxic T lymphocytes (CTL) activity. An intact nef gene is critical for high viral loads, linked to development of acquired immunodeficiency syndrome (AIDS). Certain alleles of HLA have been associated with maintaining a seronegative status such as HLA-A*1101. This nef peptide sequence (75-82) was crystallised within the class I B allele HLA B*3501 suggesting an importance of key residues required for HLA interaction resulting in a nonstandard conformational binding.Peso molecolare:975.5 g/molGad1 Blocking Peptide

The renin angiotensin system (RAS) consists of many angiotensin peptides involved in regulating functions such as blood pressure, cardiovascular function and energy balance. RAS activity is elevated in obesity and RAS is widely studied in relation to lifestyle-related diseases.Angiotensin 1-7 (Ang-(1-7)) is a component of the RAS. Ang-(1-7) is produced by angiotensin-converting enzyme 2 (ACE2), from the angiotensin II (Ang-II) peptide, as well as by prolylendopeptidase (PEP) and neutral endopeptidase (NEP) which produce Ang1 7 directly from angiotensin I (Ang-I).Ang-(1-7) broadly opposes Ang-II actions. Ang-(1-7) has vasodilatory and anti-oxidative effects, and exerts protective actions in hypertension, diabetes, and other cardiovascular disorders, Ang-(1-7) therefore represents a promising therapeutic target for cardiovascular and metabolic diseases. Ang (1-7) exerts its actions via its G-protein-coupled receptor, Mas. This novel arm of the RAS has effects that counterbalance those mediated by the classical ACE/Ang-II pathway.The C-terminal proline fro this peptide is in the D enantiomer.Colore e forma:PowderPeso molecolare:898.5 g/mol[Cys]-Galanin (1-30) Human
Galanin (1-30) is an endogenous neuropeptide with endocrine, metabolic and behavioural effects. Galanin has a role in intestinal smooth muscle contraction, insulin and somatostatin release, and synaptic neurotransmission.Galanin is widely distributed in the central nervous, peripheral, and endocrine systems. Galanin's overarching function is as an inhibitory, hyper-polarizing neuromodulator for classical neurotransmitters like acetylcholine and serotonin. Galanin interacts with 3 receptor subtypes, GalR1-3 G protein-coupled receptors inserted into the plasma membrane. GalR1 is believed to activate a Gβγ pathway to regulate MAPK activation. GalR2 can also activate the MAPK pathway, but unlike GalR1, there is detectable inositol phosphate production. GalR3 is associated with the G alpha i/o pathway receptor activation leads to a cellular influx of K+. Each receptor has been associated with neurological diseases such as GalR3 and epilepsy.Galanin protects against various physiological insults in vitro, including excitotoxicity and β-amyloid toxicity. Changes in galanin have been widely studied concerning Alzheimer's disease, and galaninergic neurons are spared in late-stage Alzheimer's relative to non-galaninergic neurones.Galanin (1-30) has been used as an agonist for the GalR2 receptor in vitro for calcium mobilisation assays to understand the role Galanin/GalR2 play in multiple sclerosis.An N-terminal cysteine residue has been included on the galanin (1-30) peptide to allow ease of site-specific conjugation to various molecules.Peso molecolare:3,258.6 g/molH-ENPVVHFFKNIVTPR-OH

Optimal peptide substrate for kallikrein-related peptidase 14 (KLK14). In its intact state this peptide is not fluorescent, however when this substrate peptide is cleaved by KLK14, Rhodamine 110 is released and thus fluorescence can then be detected. This peptide therefore allows for the quantification of KLK14 peptidase activity. KLK14 is most abundant in the skin, with lower levels in breast and prostate and may form part of the protease cascade responsible for maintaining the epidermal barrier. Aberrant KLK14 proteolytic activity is linked to several skin pathologies. Overexpression of KLK14 seen in several hormone-dependent cancers, including prostate, colon, ovarian, and breast, correlating with higher risk of disease progression. Therefore KLK14 is a potential point of therapeutic intervention in a variety of pathologies.Contains rhodamine 110 group, a widely used red fluorescent tag. The terminal carboxylic acids in this peptide have been activated by the addition of the p-tosyl moiety, allowing for easy addition of functional groups or further peptide residues.Peso molecolare:1,592.6 g/mol
