<p>Neurokinin A is a peptide that is derived from the precursor protein, preprotachykinin A, and has been found to be an endogenous ligand for the NK-1 receptor. It is involved in a wide range of physiological processes such as neurotransmission and regulation of blood pressure. Neurokinin A has been shown to inhibit adenylate cyclase activity in guanethidine-sensitive tissues and ionophores-resistant cells. The effects of Neurokinin A are not due to its ability to bind to the NK-1 receptor but rather through other mechanisms. The amino acid sequence of this peptide was first determined by cloning methods in 1984 and it has since been used extensively as a tool for studying the function of this receptor. Neurokinin A also inhibits cell proliferation in glioma cells and has been shown to have an inhibitory effect on Ca2+ concentration during electrical nerve stimulation.</p>

<p>Rituximab is a chimeric monoclonal antibody used in the treatment of some cancers like CD20 non-Hodgkin's lymphoma and a few autoimmune conditions such as rheumatoid arthritis. However, antibody treatment can lead to generation of neutralising antibodies thus curtailing the efficacy of the therapy. CD 4+ T cells are critical to initiate antibody response so identification of epitopes within molecules using T cell assays can be a vital tool for understanding the immune response and thereby prevent induction of neutralising antibodies. Within rituximab, the variable region of the light chain (41-55) was found to have strong affinity for leukocytes in a specific binding assay, the epitope was also correlated to patients who developed neutralising antibodies. This T cell epitope within rituximab in further immune studies could help design or selection of antibodies without T cell epitopes present for low immunogenicity.</p>

<p>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.<br>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.</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>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>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>
