產(chǎn)品名稱：Vasopressin RIA 產(chǎn) 地：Demeditec 產(chǎn)品貨號：DE3021 產(chǎn)品規(guī)格：100 Tests 產(chǎn)品說明： Special remarks: 1 Introduction Vasopressin, or Antidiuretic Hormone (ADH) is a nine amino acid peptide which is cyclic in nature and has molecular weight of about 1060. Its structure is very similar to that of oxytocin, differing in only two amino acids. Endogenous ADH has antidiuretic and pressor activity, both approaching 400 units per mg, with an antidiuretic-to-vasopressin ration of 1, and a biphasic plasma half-life of 2.5 and 14.5 minutes. ADH is synthesised in the hypothalamic supraoptic nucleus and paraventricular nucleus of primates and transported via exonal flow to the posterior pituitary for storage and eventual release. The clinical application of a vasopressin radioimmunoassay is in diabetes insipidus, phychogenic water intoxication, hyponatraemia, stress conditions, ADH as a neurotransmitter and hypertension studies. ADH values can be influenced by cigarettes, tea, coffee, alcohol and some drugs. 2 Principle of the Test After ethanol extraction of the plasma samples, Vasopressin is assayed by a competitive radioimmunoassay. Urinary Vasopressin can be measured directly. This radioimmunoassay is using a rabbit anti-Vasopressin antiserum and a radioiodinated Vasopressin [125I] tracer. Bound and free phases are separated by a second antibody bound to solid phase particles, followed by a centrifugation step. The radioactivity in the bound fractions is measured and a typical standard curve can be generated. The values of the extracted samples are corrected for extraction recovery. 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。
