Description： Neuron specific enolase (NSE), also known as ENO2 or gamma-enolase, is a dimeric, Mg2+-dependent enzyme that catalyzes the dehydration of 2-phospho-D glycate (PGA) to phosphoenolpyruvate (PEP) in the glycolytic pathway and catalyzes the reverse reaction in gluconeogenesis. There are three major isozymes of enolase expressed in selective vertebrate tissues from separate genes: alpha (ENO1), beta (ENO3), and gamma (ENO2). NSE is a highly expressed, specific neuron isozyme making it a useful marker for tumors derived from neuronal cells. Neuron-specific enolase is implicated as a diagnostic and prognostic marker in numerous diseases including early small cell lung cancer, prostate cancer, multiple myeloma, traumatic brain injury, acute spinal cord injury, acute ischemic stroke, and post-concussion symptoms. NSE expression and activity are increased in neuronal and glial activation and injury, risk factors implicated in neurodegenerative disease. Elevation of NSE promotes glycolysis, proliferation, activation and migration through its C-terminus to activate PI3K and MAPK signal transduction pathways while inhibition of enolase has been shown to attenuate inflammatory events. NSE can be regulated through cleavage of the C-termini by cathepsin X or inhibited directly by antibiotic SF2312. Inhibition has been proposed as a therapeutic strategy in cancer...

Description： 100B, previously called S100 beta, belongs to the S100 family within the EF-hand superfamily of Ca2+ binding proteins. S100 proteins contain two EF-hand motifs that differ in affinity, separated by a hingePurity:>95%, by SDS-PAGE visualized with Coomassie® Blue Staining. Description： 100B, previously called S100 beta, belongs to the S100 family within the EF-hand superfamily of Ca2+ binding proteins. S100 proteins contain two EF-hand motifs that differ in affinity, separated by a hinge region with a hydrophobic cleft that is exposed upon Ca2+ binding. S100B is a 91 amino acid (aa) protein, after removal of the initial methionine, and is found as homodimers of 10.4 kDa monomers. Human S100B shares 99%, 98%, 100%, 99% and 97% aa sequence identity with mouse, rat, rabbit, equine and bovine S100B, respectively. Within the S100 family, human S100B shows the highest aa identity (59%) with S100A1. S100B is expressed primarily by astrocytes and oligodendrocytes in the central nervous system, and by Schwann cells in the peripheral nervous system. Ca2+-bound S100B interacts in vitro with at least 20 cytoplasmic proteins, including several structural molecules such as tubulin and GFAP. It can inhibit the phosphorylation of these kinase substrates and others such as tau and neuromodulin. Astrocytes can secrete S100B, which then acts in a cytokine-like manner. Nanomolar concentrations of S100B are secreted constitutively, promote proliferation, and are neurotrophic and anti-apoptotic. Blood levels of S100B reflect extracellular concentrations within the nervous system, and are elevated in Down’s syndrome, Alzheimer’s disease and Tourette’s syndrome, metabolic stress, acute brain injury and brain tumors. Micromolar concentrations of S100B can be destructive and pro-apoptotic; they induce the expression of iNOS, COX-2, IL-1, IL‑6 and TNF-alpha by microglia, astrocytes or neurons. Most extracellular actions of S100B can be mediated by RAGE (receptor for advanced glycation end products), which is also a receptor for other S100 proteins...

Its main physiological function is to regulate plasma pH and maintain plasma osmotic pressure.Osrhsa (recombinant human serum albumin from Oryza sativa) is a recombinant human serum albumin developed by using rice endosperm cell expression platform (oryzhiexp) and purification platform (oryzpur). It does not contain animal derived ingredients and can eliminate the risk of blood derived virus infection. Compared with fetal bovine serum (FBS), plasma derived albumin (pHSA) and bovine serum albumin (BSA), osrhsa has higher purity and better batch stability. It can be used in various research fields, including biopharmaceutical, cell therapy and cell culture of gene therapy. It can replace serum and promote cell growth. At the same time, osrhsa is also widely used in biomedical production as drug carrier, vaccine protector, cell cryoprotectant and medical device embedding agent.ApplicationBiopharmaceuticals, human vaccines, cell culture, cell storage, chemical drug molecular carriers, medical devices, in vitro diagnosis, etc.Comparison of physical and chemical properties between OsrHSA and natural human white pHSAphysicochemical propertiespHSAOsrHSAamino acid sequenceagreementN-terminal amino acidsDAHKSEVDAHKSEVC-terminal amino acidsKLVAASQAALGLKLVAASQAALGLGlycoside modificationnothingmolecular weight (MALDl)66.554 (kDa)66.550 ( a)Isoelectric point (pl)4.84.8Drug binding activityclosethermal stabilitymp 65℃mp 65℃esterase activityidenticalcrystal structureidenticalRestrictions on use:The above products are only suitable for scientific research, laboratory and production use, and cannot be directly used in human body...

With a dissociation constant on the order of ≈10⁻¹⁴ mol/L,BackgroundStreptavidin is a tetrameric bacterial protein isolated from Streptomyces avidinii providing 4 high-affinity biotin binding sites. Streptavidin homo-tetramers have an extraordinarily high affinity for biotin. With a dissociation constant on the order of ≈10⁻¹⁴ mol/L, the binding of biotin to streptavidin is one of the strongest non-covalent interactions known in nature. Unlike egg-white avidin, which has a net positive charge at neutral pH and contains about 7% carbohydrate, streptavidin has almost no net charge at neutral pH, does not contain carbohydrate, and exhibits lower non-specific background. Streptavidin conjugates are widely used together with a conjugate of biotin for specific detection of a variety of proteins, protein motifs, nucleic acids and other molecules. This FITC-streptavidin conjugate was prepared by highly purified Streptavidin and free FITC was removed. Streptavidin (FITC) is a useful second-step reagent for the indirect immunofluorescent staining of cells in combination with biotinylated primary antibodies for flow cytometric analysis. Excitation at 488nm light leads to a fluorescence emission maximum of 520 nm.Recommended Usage：Every lot of Streptavidin-FITC is tested by flow cytometry using biotinylated primary antibodies. From this testing it is recommended that between 0.02 and 0.25 µg of streptavidin be used per 106 cells in a 100 µl staining volume... Read More |
