 胸腺五肽用途


Thymopentin 是一种主要由胸腺皮质和髓质上皮细胞分泌的生物活性肽。Thymopentin 是一种有效的免疫调节剂,具有很短的血浆半衰期 (30 秒)。Thymopentin 能促使自人类胚胎干细胞产生 T 细胞群。

 胸腺五肽制备

胸腺生成素-II的制备。
原料处理、浓缩 以小牛胸腺为原料,加入0.1mol/L NH4HCO3,搅匀提取,得碱性蛋白液,加热至70℃除去变性杂蛋白,去除沉淀,将上清液浓缩。
小牛胸腺[0.1 mol/L NH4HCO3]→碱性蛋白液[70℃, 去杂蛋白]→[浓缩]浓缩液
分离、层析、精制 经SephadexG-50和羟基磷石灰柱层析,分离,再经QAE-Sephadex柱层析,精制,即得胸腺生成素-II
浓缩液[Sephadex G-50]→[羟基磷石灰柱]层析液[QAE-Sephadex 柱]→胸腺生成素-II
胸腺生成素-II的提取
原料处理、超过滤、离心 以新鲜牛脾为原料,加入0.1 mol/L NH4HCO3,匀浆提取,得碱性可溶性蛋白。用H10×100超过滤,将滤液浓缩,水浴加热至70℃,离心15 min,留上清液。
新鲜牛脾[0.1 mol/L NH4HCO3]→碱性蛋白液[超过滤,浓缩]→[70℃,离心15min]上清液
过柱纯化 取上清液调节pH为5.2,加入阳离子交换树脂(50 mg/ml),搅拌,过滤,再将滤液调节pH为9.5,加入阳离子交换树脂(50mg/m1),搅拌,过滤,得滤液。
上清液[pH5.2, 阳离子柱]→滤液[pH9.5, 阳离子柱]→滤液
凝胶滤过、纯化 滤液经Sephadex G-75凝胶过滤,得活性TP和泛激素,再经阴离子交换树脂层析(NH4HCO3, 离子强度变化0.1-0.8mol/L),得 TP-III、杂蛋白和泛激素。
滤液[Sephadex G-75凝胶过滤]→活性TP和泛激素[阴离子树脂层析]→得TP-III、杂蛋白和泛激素。
