SucroseDensityGradientFractionationofYeastMembranes
Grow a 2 ml culture, 24 hr. at 30oC in selective mediaWhen culture is ready, use it to inoculate about 55 ml (50 ml plus 5 for O.D.600 readings) of selective media. Grow to mid-logarithmicphase (O.D.600 is about 1). This usually takes 10 hours (for 1ml of the 24 hr. culture into 50 ml media). It is helpful to inoculate 2different flasks--one with 1 ml of the 2 ml culture, the other with 0.5 ml of the 2 ml cultureSpin......阅读全文

移动区带离心的概念
在离心过程中，大小、形状、密度不同的颗粒就会分开，最后收集各区带得到要分离的物质。在此方法中，分离介质对被分离的物质必须是中性无害的，并且密度梯度较低，底部的密度比管顶部的密度大，建立密度梯度的目的是防止扩散。重要的是，待分离颗粒的密度比离心管中任何部分介质的密度都要大。常用的是蔗糖密度梯度离心(s
