Pyroglutamyl beta-Amyloid (4-14) Biotin
Pyroglutamyl β-Amyloid (4-14) Biotin is derived from Amyloid-β, which 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.This peptide contains a C-terminal Biotin tag that is covalently bonded via ethylenediamine and can be used for detection and purification. Additionally, there is a Pyroglutamyl molecule located at the N-terminal position.Peso molecolare:1,761.8 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 molecolare:4,169.54 g/molAc-CYSQFLDKYLQSTRV-OH

The coronavirus (CoV) nucleoprotein is the major component of CoV structural proteins. Also known as the nucleocapsid protein, it is an abundant RNA-binding protein critical for viral genome packaging. These factors make nucleoprotein a good target for developing new antiviral drugs. In addition, the identification of epitopes within the nucleoprotein sequence can help design more effective SARS-CoV-2 vaccines.Models have predicted epitopes exhibiting antigenicity, stability and interactions with MHC class-I and class-II molecules. Nucleoprotein (56-70) is an epitope candidate with various HLA restrictions. This epitope can be used to better vaccine design for more durable CD4+ and CD8+ T cell responses for long-lasting immunity.Peso molecolare:1,599.8 g/molC-telopeptide
C-terminal telopeptide is produced when type I collagen in the bone is degraded and so released into the blood. Within collagen structure, made up of a triple helix of 3 amino acid chains, C-telopeptide is located at the C-terminus, and at the N-terminus there is an N-telopeptide. Both the N and the C-telopeptides are involved in the formation of collagen enzymatic cross links which are crucial for Collagen properties in the connective tissues of the body such as the bone and skin. Collagen properties allow connective tissues to be strong, stiff and maintain their structural integrity. Furthermore collagen acts as a scaffold for other extracellular matrix proteins.Due to the presence of C-telopeptide in the blood following the degradation of type 1 collagen, C-telopeptide can be used to monitor the progression of bone diseases where the pathogenesis commonly involves bone degradation.Colore e forma:PowderPeso molecolare:868.4 g/molH-RRRRR-NH2

In the presence of ADP, this substrate peptide interacts with DnaK with high affinity, however when ATP is bound to DnaK, substrate binding is far weaker.Peso molecolare:785.5 g/molHLA leader peptide LVL (heavy-labeled)
Fragment of the signal peptide from endogenous HLA Class I molecules which is also found in viral glycoproteins, for example human Cytomegalovirus (hCMV) protein UL40. When presented on a cell surface via HLA-E molecules, the HLA-peptide complex binds NKG2A receptors on Natural Killer (NK) cells and some CD8⁺ cytotoxic T cells to reduce their cytotoxic activity. Blocking this interaction is an attractive opportunity for immune checkpoint (IC) approach therapies. This is relevant in both cancer therapies, and viral infections, where endogenous HLA Class I peptide presentation is exploited to escape immune attack.Peptide H-VMAPRTLL^-OH is a heavy-labeled version of PP45242, and is a Research Peptide with significant interest within the field academic and medical research.

Angiotensin II plays an essential role in the maintenance of blood pressure and blood volume. It is a peptide hormone that causes vasoconstriction, a sensation of thirst, and stimulation of the adrenal cortex and aldosterone.
Derived from the cleavage of angiotensin I by the angiotensin converting enzyme, angiotensin II is involved in the renin-angiotensin system (RAS).
Angiotensin II is the subject of much scientific research and is already the target of many anti-hypertensive drugs (ACE inhibitors, ARBs or AT1 receptor antagonists).H-PEPAKSAPAPKKGSKKAVTKA-NH2

CAS:Teduglutide is a GLP-2 analogue, in which the alanine at position 2 has been substituted with glycine making the peptide resistant to degradation by dipeptidyl peptidase-4 (DPP-4)- Teduglutide therefore has a longer half-life than GLP-2 (2-3 hours for teduglutide vs 7 min for GLP-2). Teduglutide has high bioavailability after subcutaneous administration, suggesting that teduglutide has enhanced biological activity, relative to native GLP-2.GLP-2 is a gut hormone produced in the enteroendocrine L cells of gastrointestinal tract by the cleavage of the 160-amino-acid proglucagon molecule. GLP-2 is secreted following the ingestion of food and carries out its activities via the GLP-2 G-protein coupled receptors (GLP-2Rs). GLP-2 has a range of roles within the cell, including: anti-inflammatory effects- promoting the expansion of the intestinal mucosa- stimulating intestinal blood flow- inhibiting gastric acid secretion and gastric emptying- increasing intestinal barrier function and enhancing nutrient and fluid absorption.Formula:C164H252N44O55SColore e forma:PowderPeso molecolare:3,749.8 g/molH-ETPAATEAPSSTPK^-OH
