<p>IL-1α is a cytokine protein that has been shown to be involved in the immune system. IL-1α is an activator of the receptor and is also a ligand for it. The protein has been shown to activate ion channels, which are proteins that allow ions to pass through either by diffusion or by facilitated transport. This activation causes cells to produce more hydrogen ions, which leads to an increase in the acidity of the cell. IL-1α has also been shown to inhibit cell proliferation and induce apoptosis.</p>

<p>Cysteine peptide (Ac RFAAKAA COOH) is used in combination with Lysinepeptide (Ac RFAACAA COOH) in the Direct Peptide Reactivity Assay (DPRA) test.<br>Direct Peptide Reactivity Assay is used in cosmetic applications for the characterization of the skin sensitizing potential of a substance, framed by OECD Guideline no 442.<br>The molecular initiating event (MIE) in skin sensitization is a binding between epidermal proteins and the sensitizing chemical substance. MIE is part of the adverse outcome pathway (AOP) of skin sensitization.<br>It is thanks to the properties of Lysine peptide and Cysteine peptide that the chemical binding will be able to take place, so these synthetic heptapeptides will mimic the reaction of a skin exposed to a substance.<br>Binding between nucleophilic proteins and electrophile substance will be measured by High Performance Liquid Chromatography (HPLC). Therefore, the decrease in Lysine peptide and Cysteine peptide levels will be a sign of sensitizing event. Depending on the rate of depletion, the sensitizing character of a molecule will be determined (see table at the bottom of the page).<br>In chemico DPRA test also has wider applications such as hazard classification in cosmetics, but also for pharmaceuticals and biocides. It is a good alternative to animal experimentation.</p>

<p>Insulin is a peptide hormone that is produced by beta cells in the pancreas. Insulin has several important functions, including regulation of blood sugar levels, lipid metabolism and protein synthesis. It is also involved in the regulation of cellular growth and proliferation. Insulin binds to insulin receptors on the surface of cells, activating them and allowing for the uptake of glucose into cells and storage as glycogen. Insulin is a ligand for the insulin receptor. It can also bind to other receptors, such as IGF1R, which causes activation of PI3K/AKT pathway. Insulin is an antibody that can be used as research tool or cell biology reagent.<br>INSULIN CAN BE USED TO:<br>- Measure blood sugar levels<br>- Monitor diabetes<br>- Treat diabetes<br>- Control weight gain<br>- Improve muscle mass</p>

<p>Kisspeptin-10 (Rat) / Metastin (Rat, 43-52) is a Research Tool that belongs to the group of Activators and Ligands. It is an agonist for G protein coupled receptor 54 (GPR54). Kisspeptin-10 (Rat) / Metastin (Rat, 43-52) has been shown to inhibit ion channels and act as a potent inhibitor of phosphoinositide 3-kinase. This compound has high purity and can be used in pharmacological research.</p>

<p>Methionine-Enkephalin (ME) is a peptide that has been shown to bind to the opioid receptor and inhibit the production of pro-inflammatory cytokines. ME has been shown to have an inhibitory effect on human liver cells, as well as on cultured human epidermal cells. ME may also have a role in epidermal growth factor receptors, which could be related to its anti-inflammatory effects.</p>

<p>Lys-Ala-AMC is an activator of ion channels and a ligand for receptors. It is used in research as a tool to study protein interactions, receptor pharmacology, and ion channel pharmacology. Lys-Ala-AMC binds to the α-subunit of voltage gated calcium channels and can activate these channels by increasing the rate of opening. This peptide also inhibits receptor binding by competing with the natural ligand. It has been shown to be an antagonist at the NMDA receptor and can inhibit the binding of glycine to this receptor.</p>

<p>Azido-dPEG®3-Amine is a PEG compound with two different functional groups (also known as heterobifunctional). Unlike homobifunctional PEG compounds (same functional group on both ends), this type of compounds are more versatile as have two different anchor points. Azido-dPEG®3-Amine is used as a linker and spacer to add a PEG moiety, via pegylation (a bioconjugation technique) to proteins, peptides, oligonucleotides, small molecules and nanoparticles.</p>

<p>A synthetic peptide for use as a blocking control in assays to test for specificity of SLC29A2 antibody, catalog no. 70R-7165</p>

<p>A Cholesterol Ester Transfer Protein (CETP) heavy tryptic peptide standard responsible for use in protein identification and quantitation studies. CETP is an enzyme which moves cholesterol esters from high density lipoproteins (HDL) to apolioprotein B-containing particles. This action lowers the amount of HDL which may increase the risk of the disease atherosclerosis.</p>
