Protect from sunlight.3.Keep/Store only in original container.4.Never return spills in original containers for reuse.5. Keep away from: Food and feedingstuffs.6. The solution can be transported at room temperature, but temperatures exceeding 30 °C have to be avoided. Shipping should be completed within one week.7. The solution will still work beyond the expiry date, but a lower sensitivity has to be taken into account and a precipitate may occur.8. Contaminated or leaked out substrate solution from damaged bottles should not be used and has to be destroyed.3、Effective Components and Principle of FunctionA citrate buffer system (pH 4.5 - 5.0) contains the following effective components:Hydrogen peroxide3,3`,5,5`-Tetramethylbenzidine (TMB)precipitating reagentPeroxidase catalyses the decomposition of hydrogen peroxide, taking electrons from TMB (byoxidation). Oxidation of TMB forms a radical cation that stabilizes by dimerisation and shows the typical blue colour. This blue cation is stabilized by forming an insoluble complex with the precipitating reagent. So at positions with horseradish peroxidase activity a blue precipitate will appear. This precipitate is very fine so that even the smallest dots can be coloured regularly.4、Biosafety informationThis mixture is not classified as hazardous in accordance with Regulation (EC) No 1272/2008；Hazardous components：none (according to Regulation (EC) No 1907/2006 (REACH))5、Advantage1. Rapid precipitation2. Strong adherence to plastic surfaces3. Short reaction time4. Intensive dark blue colour5. Homogeneous staining pattern6、Instruction for usageFor bottling consider the following instructions:•Work in a dust free and darkened room.• Pay attention that the solution has no contact with metal parts (leading to catalysis) of yourinstruments. Closed systems of silicon tubes are favoured.• Clean all instruments and vessels very carefully.• Never touch parts of the instruments that are in contact with the solution with the naked hand. Wear powder free gloves.• Close the bottles immediately to minimize the influence of light and dust.• Use bottles that are not permeable to light, made from HDPE or PP.7. General Instructions for the Use on Microchips• This solution should only be used by qualified laboratory staff familiar with the basics of immunological methods.• Note: The substrate solution is very sensitive to impurities. This is why you should never immerse pipette tips in storage bottles. Unused solution is never returned to the bottle! Don't swap the bottles for the cups!• Substrate Solutions Test systems for instrumental measurements on glass or plastic surfaces (polycarbonate or polystyrene).• Depending on the system, it may be sufficient to wash the microarrays after incubation with the conjugate and then cover them with the substrate solution. Arrays can be developed with a rocking motion until visible color appears (approximately 5 to 10 minutes). Measurements can be performed using wet arrays or after washing with distilled water and drying. Dry microchips can be used for recording purposes. (Note: some glues will destroy colored deposits)...

It is composed of noncovalently linked glycosylated alpha and beta chains. The alpha subunit (CG alpha ) is also a component of Follicle-Stimulating Hormone (FSH), Thyroid-Stimulating Hormone, and Chorionic Gonadotropin. The unique beta subunit confers the protein’s specific biological action and is responsible for the interaction with its receptor. The approximately 20 kDa human CG alpha subunit shares 73% and 72% amino acid (aa) sequence identity with the mouse and rat orthologs, respectively. The approximately 18 kDa human LH beta subunit shares 71% and 72% aa sequence identity with the mouse and rat orthologs, respectively. Multiple isoforms of LH exist due to differences in the post-translational glycosylation, sialylation, and sulphation modifications of its subunits. The composition, longevity, and activity of the different LH isoforms vary throughout a woman’s menstrual cycle and reproductive life cycle. LH is produced and secreted by the anterior pituitary gland. Its secretion is controlled by Gonadotropin-Releasing Hormone from the hypothalamus; however, LH secretion can also be stimulated by estradiol. LH works in concert with FSH to regulate female reproduction; FSH stimulates follicular growth and LH induces ovulation. LH also drives formation of the corpus luteum by promoting progesterone production. Additionally, LH has been suggested to stimulate the adrenal gland in postmenopausal women to induce secretion of sulfated DHEA, a precursor to androgens. In the testis, LH induces Leydig cell production of testosterone. Hypersecretion of LH has been shown to occur in women with polycystic ovary syndrome and is associated with an increased risk of infertility and miscarriage. Additionally, increased serum LH levels are associated with decreased cognition and have been implicated in the development and progression of Alzheimer’s disease. receptor into an A-frame...

It is a secreted phosphoglycoprotein that belongs to the clade F subfamily, serpin superfamily of proteinase inhibitors. The PEDF is a noninhibitory serpin with neurotrophic, anti-angiogenic, and anti-tumorigenic properties. It is synthesized as a 418 a.a. about 50kDa precursor that contains a 19 a.a. signal sequence and a 399 a.a. mature region that shows a pyroglutamate at Gln20. Like other serpins, it contains three β-sheets, 810 α-helices, and a C-terminal RCL (reactive center loop). Unlike other serpins with Ser protease inhibiting activity. PEDF has functions of inducing extensive neuronal differentiation in retinoblastoma cells, inhibiting of angiogenesis. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity. PEDF is researched as a therapeutic candidate for treatment of such conditions as choroidal neovascularization, heart disease, and cancer... Read More |
