聚丙烯酰胺凝胶盘状电泳(简称盘电泳)具有很高的分辨率,在许多学科实验中得到广泛应用。已知影响盘电泳分辨率的因素有温度、电流强度、缓冲液的pH值及离子强度、样品量和分离胶浓度等[1]。我们在实验中发现,盘电泳的时间对卫氏并殖吸虫囊蚴粗抗原的分辨率有重要影响。 Polyacrylamide gel disk electrophoresis (referred to as disk electrophoresis) with high resolution, in many disciplines experiment has been widely used. Factors known to affect the resolution of plate electrophoresis are temperature, amperage, buffer pH and ionic strength, sample volume, and gel concentration [1]. We found in experiments that the time of plate electrophoresis has a significant effect on the resolution of Paragonimus westermani crude antigen.
