E01A0047 Human Adrenomedullin ELISA kit Human Adrenomedullin ELISA kit is suitable for the detection of samples from human species. Adrenomedullin can also be called AM, ADM, ADM precursor, ADML. Specifications of Human Adrenomedullin ADM ELISA kit Principle of the Assay AM ELISA kit applies the competitive enzyme immunoassay technique utilizing an anti-AM antibody and an AM-HRP conjugate. The assay sample and buffer are incubated together with AM-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the AM concentration since AM from samples and AM-HRP conjugate compete for the anti-AM antibody binding site. Since the number of sites is limited, as more sites are occupied by AM from the sample, fewer sites are left to bind AM-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The AM concentration in each sample is interpolated from this standard curve.

Vat dyes dyeing process Vat dyes do not dissolve in water, while when reduced to be leuco salt by reducing agent under alkaline conditions, they can dissolve in water and get feature of immediacy with cellulose fibers, which is the way to achieve the purpose of dyeing. Then stable shade and good color fastness would come out via oxidation and soaping. Reduction of dyes Insoluble reducing dye will change into soluble leuco. Different levels of the best staining methods are brought out according to the reduction dyes’ reduction potential and level of its immediacy to fibers. Dye-uptake of leuco The leuco is absorbed by fiber and then it is diffusing into the fiber. It is necessary to use soft water or softened water in dyeing process. Hereby it is suggested to add the water softener for 1g/L to some poor quality cotton calcium, magnesium ions, but also the iron, copper ions which are absorbed by the pipe into the dye bath, and finally keep the solubility of leuco.

Coating Process: Silver Mechanical Zinc Flake Coating Geomet Anti Corrosion For Brake Disc 1 Attentions: 1. Other chemicals such as any kinds of acid, alkali salt can not be mixed into coating, for these can activate Zn & Al plate to aging the coating. 2. Avoid irradiation of sunshine and ultraviolet ray for long time when operating, otherwise it will accelerate aging or polymerization of the coating . 3. It is very important to control the temperature of coating. If the temperature of coating changes when operating, it will effect the viscosity, then effec the coating quatity on workpiece. So the relations among temperature,viscosity and spinning process shoud be controlled well when coating. 4. The viscosity will be different if coating method is different. Choose low data if spray coating,and choose high data if dip spin coating.
