產(chǎn)品名稱：Metanephrine Plasma Fast Rack 產(chǎn) 地：Demeditec 產(chǎn)品貨號(hào)：DEE8100 產(chǎn)品規(guī)格：96 Tests 產(chǎn)品說明： Special remarks: Intended use and principle of the test Enzyme Immunoassay for the quantitative determination of free Metanephrine in plasma. First, the plasma proteins are removed by precipitation. After this Metanephrine (Metadrenaline) is quantitatively acylated. The subsequent competitive ELISA kit uses the microtiter plate format. The antigen is bound to the solid phase of the microtiter plate. The acylated standards, controls and samples and the solid phase bound analytes compete for a fixed number of antiserum binding sites. After the system is in equilibrium, free antigen and free antigen-antiserum complexes are removed by washing. The antibody bound to the solid phase is detected by an anti-rabbit IgG-peroxidase conjugate using TMB as a substrate. The reaction is monitored at 450 nm. Quantification of unknown samples is achieved by comparing their absorbance with a reference curve prepared with known standards. The antisera used in this test kit only recognise the biologically relevant L-forms of metanephrines. Commercially available synthetic normetanephrine or metanephrine is always a mixture of the D- and L-forms. The ratio between both forms differs widely from lot to lot. This has important implications if synthetic metanephrines are used to enrich native samples. As only about 50% of the synthetic metanephrines - the L-portion - will be detected by use of this kit, spiked samples will be underestimated. Therefore native samples containing solely the L-form should be used. 上海玉博生物技術(shù)有限公司在為生命科學(xué)領(lǐng)域提供豐富的產(chǎn)品與信息資源方面處于國內(nèi)**地位，公司提供的產(chǎn)品涵蓋了二十多個(gè)國家近五十萬種產(chǎn)品，而且產(chǎn)品的數(shù)量與信息在不斷的增長和更新，公司提供的產(chǎn)品能夠使生命科學(xué)工作者加快對生物化學(xué)，分子生物學(xué)，細(xì)胞生物學(xué)以及蛋白質(zhì)組學(xué)研究的認(rèn)知，以及分子診斷和臨床醫(yī)學(xué)領(lǐng)域的應(yīng)用。
