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.

This product has disulfide bonds between Cys1-Cys15 and Cys3-Cys11 and is available as a 0.1mg vial. Big Endothelin-1 (Human, 1-38) is part of the full lengthed 29 amino acid peptide Big Endothlin-1 which is a precursor peptide of the vasoconstrictorEndothelin-1 (ET-1). ET-1 exhibits vasoconstrictive properties and is an activator of endothelin G-protein coupled receptors. Furthermore ET-1 is produced when inflammation, vascular stress or hypoxia occurs. In vivo Big Endothelin-1 has a greater half life compared to ET-1 and therefore makes it useful to study secretory activity in the endothelial system.
Overall Big Endothelin-1 (Human, 1-38) can be used as a research tool for studying protein interactions, receptor activation and function, and ligand binding. This peptide is also used in pharmacology to study the effects of therapeutic agents on receptor activity and expression.

Cysteine peptide (Ac RFAAKAA COOH) is used in combination with Lysinepeptide (Ac RFAACAA COOH) in the Direct Peptide Reactivity Assay (DPRA) test.
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.
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.
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.
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).
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.

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.
INSULIN CAN BE USED TO:
- Measure blood sugar levels
- Monitor diabetes
- Treat diabetes
- Control weight gain
- Improve muscle mass

HG1 toxin is a peptide that is found in the venom of the scorpion Heterometrus fulvipes. It is a member of the short-chain scorpion toxins, which are composed of a single chain of amino acids. This protein has been shown to bind to potassium channels and inhibit their function, leading to paralysis of the prey's nervous system. HG1 toxin has been shown to be able to activate or inhibit ion channels and other receptors. It can also bind to ligands such as peptides or antibodies and affect cellular activity. HG1 toxin is produced by recombinant DNA technology and purified by HPLC for use in biochemical research and pharmacological studies.

CJC-1295 is a synthetic peptide, which is an analogue of growth hormone-releasing hormone (GHRH). It is synthesized through recombinant DNA technology, which allows for precise control over its sequence and length. This particular peptide is designed to bind to GHRH receptors in the pituitary gland. By activating these receptors, CJC-1295 stimulates the release of growth hormone (GH) into the bloodstream.The primary function of CJC-1295 is to influence the endocrine system, particularly enhancing the release of endogenous growth hormone. It achieves this by increasing the amplitude and frequency of GH pulses without affecting the natural negative feedback mechanisms that regulate GH production. This mode of action distinguishes CJC-1295 from other growth hormone therapies, as it promotes a more physiological pattern of hormone secretion.CJC-1295 is used in various scientific contexts, primarily in research focusing on growth hormone deficiencies, muscle wasting conditions, and certain metabolic disorders. Its ability to increase GH release also makes it a subject of interest in studies related to aging, tissue repair, and regeneration. The longer half-life of CJC-1295 compared to natural GHRH peptides further enhances its applications in research, allowing for more sustained and controlled experimentation.

Myelin oligodendrocyte glycoprotein (MOG) is a myelin protein found in the central nervous system. MOG is a ligand for CD200, which is an inhibitory receptor expressed by astrocytes. It has been shown that MOG can induce the proliferation and differentiation of primary cultures of rat astrocytes in vitro. MOG induces the production of reactive oxygen species in mitochondria and increases the expression of acid-binding protein, which are both important factors in the demyelination process. MOG has also been implicated as a potential factor in the development of multiple sclerosis. Further research into this protein may lead to new treatments or cures for disorders such as encephalomyelitis, nervous system diseases, or even cancer.
