This 13 amino acid peptide was first isolated from bovine hypothalamus and was named from its neuronal localization. It was detected in the central nervous system (CNS) and peripheral tissues mainly in the gastrointestinal tract. This bioactive form of neurotensin post-translationally modified at a Glu residue was isolated from porcine intestine. In the CNS, neurotensin has dual function of neuromodulator of dopamine transmission and of anterior pituitary hormone secretion. It also shows potent hypothermic and analgesic effects in the brain. Neurotensin has been implicated in the pathophysiology of schizophrenia, Huntington, and Parkinson diseases. | |

(2)酸和盐浓度等比例也增减时,溶液的pH值不便。
(3)酸和盐浓度相等时,缓冲液的缓冲效率为最高,比例相差越大,缓冲效率越低,一般地说缓冲液有效缓冲范围为PK±1pH
酶提取技术,属地球化学勘查学科。其是由克拉克(J.R.Clark)等人于20世纪80年代末和90年代初研制出的一种利用葡萄糖氧化酶提取矿物颗粒表面的非晶质锰的氧化膜寻找隐伏矿的方法。1995年以后已广泛应用。
2.尿素:有膜蛋白的损失
3.RIPA:用于磷酸化蛋白的温和裂解,不破坏磷酸基团
甲液:0.05mol/L Na2HPO4溶液 :称取磷酸氢二钠9.465g 7.099g,加蒸 馏水至1000ml ;
乙液:0.05mol/L KH2P04溶液: 称取磷酸二氢钾, 9.07g 6.803g,加蒸馏水至1000m1.
将甲乙液分装在棕色瓶内,于4℃冰箱中保存,用时甲、乙两液各按不同比例混合,即可得所需pH的缓冲液,见下表:
pH 甲液ml 乙液mI
5.29 2.5 97.5
5.59 5.0 95.0
5.91 10.0 90.0
6.24 20.0 80.0
6.47 30.0 70.0
6.64 40.0 60.0
6.81 50.0 50.0
6.98 60.0 40.0
7.17 70.0 30.0
7.38 80.0 20.0
7.73 90.0 10.0
8.04 95.0 5.0
你要配制pH=6.8的PBS,可用甲、乙液各50ml混合即可.
