Shibayagi 大鼠胰岛素 ELISA试剂盒(T型)

  胰岛素是由胰脏内的胰岛β细胞分泌,分子量约5800,等电点在5.4左右的一种蛋白质激素。

  A6-A11、A7-B7、A20-B-19之间形成二硫键,在酸性溶液或者不含Zn离子的中性水溶液中形成二聚体,在含锌离子的中性溶液中,则形成含2个Zn离子的六聚体。

  肝脏、肌肉、脂肪组织是主要的靶组织,分别有以下的作用。

肝脏:促进糖原、蛋白质、脂肪酸合成、促进糖类的摄取和利用、抑制糖异生。

肌肉:糖类、氨基酸、K细胞膜通透性增大、促进糖原、蛋白质的合成、抑制蛋白质分解。

脂肪组织:葡萄糖细胞膜通透性增大、促进脂肪酸的合成。

  胰岛素是细胞内的合成单链胰岛素原通过二硫键结合一起形成的。在酶分解作用下被激活,C肽和胰岛素分离。

简要介绍丙酮酸钠的作用-技术文章

简要介绍上海金畔生物科技有限公司丙酮酸钠的作用

丙酮酸钠是天然存在于人体内,并参与全身各组织和器官的代谢。是一类内源性小分子物质,在医学上、诊断试剂以及医疗器械中被广泛用作缓冲剂、赋形剂和抗氧化剂。

丙酮酸钠的作用

抗氧化

K.R.Hegde等[1]的研究表明丙酮酸钠能够有效阻止在视网膜中活性氧自由基诱导的糖酵解障碍,并且能够维持NAD+/NADH的正常比例?。Yuri Zilberter等的研究显示丙酮酸能够有效的清除ROS,在神经病理学中发挥显著地抗氧化作用;同时氧化应激的发生能够激活PARP-1导致胞质中NAD +的消耗,抑制糖酵解,细胞由于缺少能量而导致死亡,丙酮酸能够减少激活的PARP-1,恢复能量供应保护神经细胞。PAUL D等[3]的实验结果显示丙酮酸钠可能有助于改善甚至防止肝细胞功能障碍发生后的出血性休克,丙酮酸钠能够通过抑制caspase-3以及改善GSH/GSSG比率,抑制细胞凋亡,证明外源性丙酮酸钠同样具有改善细胞氧化还原状态的作用。Bryan Troxell等[4]用对H2O2敏感的致病性螺旋体暴露于H2O2,结果发现丙酮酸钠能够清除H2O2,降低ROS及RNS的水平,有效抑制在氧化应激状态下DNA的损伤,提示可利用宿主内的丙酮酸清除过氧化氢和其他活性化合物的损伤。N. Moriguchi等[5]的实验结果显示1mM的丙酮酸不仅可以阻止H2O2浓度升高杀伤正常细胞,还可以抑制暴露于H2O2的细胞中ROS的生成,这些结果证明丙酮酸具有能够中和H2O2的氧化能力,可以通过抗氧化实现细胞保护的作用。

抗炎

S.K.GUPTA等[6]探索丙酮酸钠对急性和慢性炎症大鼠模型的抗炎活性,以剂量依赖的方式口服3种不同剂量水平125,250 和500 mg/kg丙酮酸钠,丙酮酸钠能够显著抑制大鼠角叉菜胶性急性足肿胀,500 mg/kg剂量水平的丙酮酸钠的效果与一个标准的12.5 mg/kg双氯芬酸钠相同,表现出显著地抗炎活性。John等[7]研究丙酮酸钠治疗慢性阻塞性肺疾病(COPD)的安全性及治疗效果,COPD是由ROS和RNS部分介导的气道炎症反应,受试者分为丙酮酸钠组和安慰剂组,与对照组相比丙酮酸钠组的FEV1在6周后增加,4周后呼出的NO水平明显增加(P<0.01),结果证明外源性丙酮酸钠能够在体内发挥显著地抗炎作用。Qing Wang等[8]研究了丙酮酸作用于实验性中风的影响,实验结果显示丙酮酸能够显著保护脑组织,减少脑梗死面积,免疫组化结果显示丙酮酸减少中性粒细胞浸润和小胶质细胞的激活,同时能够减少NF-κB的DNA的结合能力。

丙酮酸钠精制(若不合格需精制):

在溶解罐中加入:纯化水400kg、丙酮酸2.5kg。开搅拌,开投料口,缓缓加入待处理不合格丙酮酸钠240kg,蒸汽升温至50~55℃,待丙酮酸钠完全溶解,将溶解的丙酮酸钠溶液缓缓加入抽滤缸中,将滤液抽入水析罐中,滤毕,将1440kg 95%乙醇,经过滤器抽入水析罐内,抽毕,冷却至0~5℃,离心甩干,送烘房。
