Abstract:

  【Abstract】 Objective To detect the difference of the salivary protein spectrum from Aedes albopictus aged 3 days with blood-feed and sugar-feed, respectively.  Methods The  salivary  protein was detected with Pierce BCA Protein Assay Kit and SDS-PAGE. Results The amount of salivary gland proteins in sugar-feed and blood-feed mosquitoes aged 3 days was approximately (1.243±0.460)μg/female and (0.945±0.460)μg/female, respectively.  There were at least twelve major proteins in sugar-feed mosquito salivary glands analyzed by SDS-PAGE, and no difference was detected in the electrophoretic bands between sugar-feed and blood-feed mosquitoes salivary gland. Conclusion No specific protein was induced after Ae.albopictus feeding blood, but the total protein of salivary gland per female decreased after a blood meal.

摘要:

  【摘要】 目的 探讨3日龄白纹伊蚊雌蚊吸食糖水组和饱血组唾液腺总蛋白谱的差异。方法 分别采用Pierce蛋白定量试剂盒和SDS?PAGE电泳分析白纹伊蚊3日龄吸食糖水组和饱血组成蚊唾液腺蛋白质浓度和蛋白谱。结果 糖水组蚊虫单对唾液腺蛋白质质量约为(1.243±0.460)μg,饱血组约为(0.945±0.460)μg;SDS?PAGE检测到糖水组唾液腺总蛋白有12条主带,糖水组与饱血组唾液腺总蛋白条带没有变化。结论 白纹伊蚊雌蚊饱血后唾液腺总蛋白无特异条带诱导,但饱血后单对唾液腺总蛋白下降。
