<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>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.</p>

<p>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.</p>

<p>Seglitide is a cyclic peptide that is a model system for the receptor activity of somatostatin.

Seglitide also activates locomotor activity in mice, suggesting that it may have some clinical relevance. Structural analysis has revealed that seglitide's amino acid sequence is similar to somatostatin's, making them closely related compounds. It also binds to DNA-dependent RNA polymerase, preventing transcription and replication.</p>
