Formule :C74H115N21O17Masse moléculaire :1,570.8 g/molApolipoprotein KV domain (67 - 77)
Vascular lipid deposition and altered lipid profiles are typical when unregulated angiogenesis is occurring, it is often seen in vascular disorders such as cancer and atherosclerosis. Apolipoprotein a (ApoA) functions as part of the lipid transporter complex high-density lipoproteins (HDL) to ensure lipid homeostasis and therefore the balance of angiogenesis. Within ApoA the Kringle5 (KV) domain (67 - 77), also known as KV11, has been identified as the region of ApoA that exerts anti-angiogenic effect. KV11 was shown in tumour cells to inhibit angiogenesis and consequently inhibits tumour progression. KV11 targets the angiogenesis c-Src/ERK pathway by blocking the activation signals received from vascular endothelial growth factor (VEGF). KV11 provides a new research potential for an anti-angiogenesis and anti-tumour therapeutic agent.Masse moléculaire :1,447.66 g/molNeuropeptide Y (3-36) Human,Rat
Neuropeptide Y (NPY) is a peptide involved in the gut-brain axis. Neurons express it in both the brain and the gut. However, expression is significantly increased upon nerve injury. NPY is the most abundant neuropeptide within the brain and is expressed by many neuronal systems, and several important pathways utilising NPY as a neurotransmitter have been identified. Mammalian NPY acts as a vasoconstrictor by affecting blood pressure around peripheral nerves, while it also acts on food intake and emotional regulation.The primary receptor subtypes on which NPY acts in the brain are the Y1 and Y2 receptors but also include Y4, Y5 and y6 (a human pseudogene). Y1 and Y2 increase blood pressure, Y1 and Y5 increase food intake, and Y2 and Y4 decrease food intake.NPY has been linked to psychiatric disorders such as anxiety and depression. Low levels of NPY have been observed in patients with major depressive disorder. Rodent models are used to understand better NPY and its receptors' role in emotional regulation.Masse moléculaire :4,271.69 g/molBrAc-TWPKHFDKHTFYSILKLGKH-NH2

Custom research peptide; min purity 95%. For different specs please use the Peptide Quote ToolMasse moléculaire :1,732 g/molKisspeptin 14 human
The biologically active C-terminal region of Kisspeptin. Kisspeptin, is cleaved from a 145 amino acid precursor to a 54 amino acid peptide in humans and a 52 amino acid peptide in mice. Smaller isoforms of 14, 13 and 10 amino acids have also been isolated in humans, each sharing the common C-terminal sequence. Kisspeptin-14 (KP-14) has equivalent receptor binding efficiency and potency to full length Kisspeptin.Kisspeptin, a product of the KISS1 gene, is a hypothalamic neuropeptide that stimulates gonadotropin-releasing hormone (GNRH) neurons and drives fertility. When energy balance is severely altered (either negatively or positively), Kiss1 expression and fertility are compromised. Kisspeptin neurons are responsible for the transmission of key homeostatic information to GNRH neurons, which is likely to mediate the link between energy balance and fertility. Leptin, ghrelin, pro-opiomelanocortin (POMC), and neuropeptide Y (NPY) have been suggested as modulators of this process.Kisspeptin binds specifically to the G-protein-coupled receptor-54, now known as Kiss1r, which is expressed in almost all GNRH neurons. Kisspeptin plays an essential role in reproduction, and Kiss1r mutations have been isolated in cases of defects in sexual development. Kiss1r is also expressed in other areas of the brain and periphery, highlighting other possible roles for kisspeptin outside of reproduction. Due to kisspeptins importance in reproduction it is synthesized in excess to ensure reproductive success.Couleur et forme :PowderMasse moléculaire :1,740.8 g/molH-ESLSSYWESAK^-OH

LL-37 is a member of the large cationic family of anti-microbial peptides called cathelicidins which have broad-spectrum anti-microbial activity and are expressed in many species. The only cathelicidin found in humans is LL-37, this is produced in epithelial cells, by proteolytic cleavage from the C-terminal of the hCAP-18 protein. LL-37 can be processed into different forms of anti-microbial peptides. As well as its anti-microbial properties LL-37 also regulates many aspects of the innate immune system and overexpression of LL-37 has been linked to autoimmune diseases such as asthma and psoriasis, making LL-37 the most studied form of the human cathelicidin peptides.More recently, studies have shown that LL-37 binds to SARS-CoV-2 S protein and inhibits binding to its receptor hACE2, which may inhibit viral entry into the cell. LL-37 is upregulated by vitamin D, therefore this may be one mode of action for the positive outcomes seen with vitamin D treatment for Covid-19.Couleur et forme :PowderMasse moléculaire :597.4 g/molH-HLDDLK^^-OH

SARS-CoV-2 NSP7 (46-60)
SARS-CoV-2 NSP7 is part of the RNA-dependent RNA polymerase heterotetramer for mediating coronavirus RNA synthesis. NSP7 and NSP8 form a channel to confer processivity on RNA polymerase. NSP7 aids in stabilising NSP12 regions involved in RNA binding and is essential for a highly active NSP12 polymerase complex. These factors make NSP7 a good target for developing new antiviral drugs. In addition, the identification of epitopes within the NSP7 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. NSP7 (46-60) 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.Masse moléculaire :1,678.9 g/molH-HGEGTFTSDLSKQMEEEAVRLFIEWLKNGGPSSGAPPPS-NH2
Exendin-4 is a 39-amino acid peptide incretin mimetic. Exendin-4, also known as Exenatide, was originally isolated from the venom of Gila monster lizard called Heloderma suspectum1. Exendin-4 is a long-acting analog of the mammalian intestinal hormone glucagon-like peptide I (GLP-1) and therefore exhibits glucoregulatory activities to control plasma glucose levels2. Exendin-4 enhances insulin synthesis and secretion in a glucose-dependent manner, while downregulating inappropriately high glucagon release, slowing gastric emptying and decreasing appetite2. The increase in maximum insulin secretion is due to a greater increase in cAMP production in pancreatic β cells3. Exendin-4 is a potent agonist of the Glucagon-Like Peptide-1 Receptor (GLP-1R ; Kd = 136pM).H-LNIPTDVLK^-OH

Formyl-MLF-[Cys(AF488)] is composed of the chemotactic peptide: N-formyl-methionine-leucine-phenylalanine. N-formyl-methionine is the N-terminal amino acid present on bacteria and allows the bacteria to interact with phagocytic cells such as macrophages and monocyte-derived dendritic cells through surface formyl-MLF receptors. As a result Formyl-MLF labelled with the fluorescent dye, Alexa Fluor 488 can be used as a marker of bacterial infections. It has also been demonstrated that the use of multiple formyl-MLF moieties can target polymeric drug delivery molecules to phagocytic cells. In addition to Alexa Fluor 488's application in marking bacterial infections, its properties of being photo-bleaching resistant and having a high quantum yield allow it to carry out its most common use in the visualisation and location of dendritic structures and synapses.Masse moléculaire :1,237.3 g/molSARS-CoV-2 NSP13 (231-245)
The SARS-CoV-2 non-structural protein 13 (NSP13) has been identified as a target for anti-viral therapeutics due to its highly conserved sequence and is essential for viral replication. NSP13 is part of the helicase superfamily 1B. As an NTPase and RNA helicase, NSP13 binds to RNA-dependent RNA polymerase and acts in concert with the replication-transcription complex to stimulate backtracking and further activate NSP13 helicase activity. These factors make NSP13 a good target for developing new antiviral drugs. In addition, the identification of epitopes within the NSP13 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. NSP13 (231-245) is an epitope candidate with various predicted HLA restrictions. This epitope can be used to better vaccine design for more durable CD4+ and CD8+ T cell responses for long-lasting immunity.

14-3-3 zeta/delta (28-41)
14-3-3 proteins are highly conserved from yeast to plants and mammals where they are found in various organs and tissues. 14-3-3 proteins regulate numerous signalling pathways via direct binding to proteins carrying phosphorylated 14-3-3-binding motifs, several hundred binding partners have been identified for 14-3-3 proteins. Their functions include a role in viral infections and innate immunity, protein trafficking, cell-cycle control, apoptosis, autophagy and other cell signal transduction pathways, as well as the associated mechanisms. There are seven 14-3-3 subtypes (alpha/β,γ, ε,η, σ, τ [also called θ] and ζ/δ) in mammals. 14-3-3 ζ has been shown to interact with Hepatitis B virus (HBV) protein X (HBx), E6 oncoprotein, Caspase-2: a protease involved in apoptosis, and to be is involved in the subcellular localisation of the FOXO forkhead transcription factor. 14-3-3 ζ acts as a molecular block that covers the DNA-binding site of FOXO4, thus blocking its interaction with the target DNA. 14-3-3 ζ also participates in the TLR3-TICAM-1 signalling pathway by promoting multimerization of TICAM-1 to form a signalosome. 14-3-3 ζ isoform may also be the target of SARS-CoV-2 in the nervous system.Masse moléculaire :1,547.7 g/molH-S^LS^LSPGK^-OH
