摘要: 通过改变非洲爪蟾卵母细胞的消化时间、消化次数、消化用酶量等, 优化乙酰胆碱受体的表达条件。结果显示, 采用两步消化法, 在经过0.5 mg/mL的胶原酶消化50-70 min之后得到的非洲爪蟾卵母细胞的状态较好, 利于受体的表达;同时优化了受体在非洲爪蟾卵母细胞上的表达条件。试验所获得的优化表达条件对建立非洲爪蟾卵母细胞受体表达体系具有重要意义。

Abstract: It was to optimize the conditions of AChRs expressed on Xenopus laevis oocytes, including the oocytes’ digestion time, frequency and the amount of collagenase. Results showed that when using two-step digestion method and 0.5 mg/mL concentration of collagenase, the isolated Xenopus laevis oocytes was beneficial to express AChRs. The conditions of receptor expression on the oocytes were also optimized. The optimized expression methods are significant to set up the expression system of AChRs on Xenopus laevis oocytes, which are the basis for screening new drugs to target AChRs with this experimental model.
