| 产品名称: | Arg-vasopressin Peptide |
| 产品链接: | http://www.abbiotec.com/peptides/arg-vasopressin |
| 货号: | 350151 |
| 规格: | 1 mg |
| 产品描述: | Arg-vasopressin is a neurohypophysial hormone found in most mammals, which corresponds to aa21-28 of vasopressin-neurophysin 2-copeptin (AVP-NPII). Vasopressin has a direct antidiuretic action on the kidney and also causes vasoconstriction of the peripheral vessels. Defects in AVP-NPII are the cause of autosomal dominant and recessive neurohypophyseal diabetes insipidus (ADNDI and ARNDI). |
| 序列: | H-Cys-Tyr-Phe-Gln-Asn-Cys-Pro-Arg-Gly-NH2 (Cys1-Cys6) or H-CYFQNCPRG-NH2 (Cys1-Cys6) |
| 分子式: | C46H65N15O12S2 |
| 分子量: | 1084.23 g/mol |
| 纯度: | Purity > 95% by HPLC |
| 别名: | Arg-vasopressin; vasopressin-neurophysin 2-copeptin; AVP-NPII; AVP; ARVP; VP; Arg8-vasopressin; [Arg8]-vasopressin |
| 形态: | Each vial contains 1 mg of lyophilized solid packaged under an inert gas and supplied as a trifluoroacetate salt. |
| 溶解方法: | Distilled water for a solution up to 2 mg/ml, otherwise we recommend using acetonitrile. |
| 保存方法: | Store at -20°C. The product is hygroscopic and must be protected from light. Product is guaranteed one year from the date of shipment. Following reconstitution, aliquot and store at -20°C. |

文献和实验Measurement of Arginine Vasopressin
Arginine vasopressin (AVP) is a peptide hormone synthesised in the hypothalamus and secreted from nerve terminals within the posterior pituitary gland. Secretion is primarily under osmoregulatory control and levels rise in plasma in response
也称抗利尿激素(antidiuretic hormone,ADH)。为垂体后叶组织所提纯的一种激素。由下丘脑的视上核的神经内分泌细胞所合成。合成后,附着于神经纤维鞘内的载体蛋白,沿视上核—垂体束的轴浆向下流动而至垂体后叶微血管基底膜附近,贮存于后叶,并经常有少量释放入血液中。当视上核受刺激时,冲动沿下丘脑→垂体束到达神经垂体内大量释放加压素。其主要化学结构为8个氨基酸组成的多肽。其中两个半胱氨酸作为一个胱氨酸计算。人和大多哺乳类为精氨酸加压素。猫的加压素为赖氨酸加压
二个以上的α -氨基酸以肽键连接起来而形成的化合物。根据构成氨基酸的数目 2、 3、 4……叫做二肽( dipeptide)、三肽、四肽……。大体上由 10以下的肽键形成的肽总称为寡肽 ( Oligopeptide),由多数肽键构成的肽总称为多肽。每个肽按照构成它的氨基酸的名称,从具有游离α -氨基的末端氨基酸依次命名。例如 称为甘氨酰丙氨酸的二肽。蛋白质是由一条或几条长链状多肽构成的。象谷胱甘肽和肌肽那样的低
