中文摘要:本实验试图建立一套蜜蜂脑神经细胞游离钙离子浓度([Ca2 +]i )的体外测定方法。采用Fura-2 acetoxymethyl
ester( Fura-2 AM)作为荧光指示剂,对体外培养的意大利蜜蜂Apis mellifera ligustica Spinola 脑神经细胞的
[Ca2 +]i 测定方法进行了探索,研究了不同浓度的Fura-2 AM 及不同的孵育时间对细胞钙离子测量ratio 值的影
响。结果测得细胞ratio 值随Fura-2AM 浓度的增大而降低,孵育时间也会影响ratio 值,综合比较得到最佳孵育时
间以及最佳染料浓度,并在此基础上制订了一套意大利蜜蜂蜜蜂脑神经细胞钙离子浓度的测定方法,这对进一步
建立以蜜蜂神经细胞钙离子浓度变化作为衡量环境有毒物质对蜜蜂的风险研究具有重要意义。
英文摘要:
- A prototype in vitro method to measure intracellular free calcium concentration ([Ca2 +]i ) in honeybee brain
cells was developed and tested. Fura-2 AM was used as a florescence indicator to measure intracellular calcium ion
concentration ratio values and incubation time ratio was also recorded and analyzed using META FLOUR software. The
results revealed that cell ratio values decreased among groups with increased concentration of Fura-2 AM during cell
incubation,and there were highly significant differences between groups ( P < 0. 01 ) . Similarly,it was clear that
incubation time can potentially affect ratio values; for example only 10 mins incubation resulted in ratio values significantly
lower than the other treatments.
