A comparison was made of the performance of swing-out and vertical ultracentrifuge rotors in the detection of rubella-specific IgM on a sucrose density gradient. Tests were performed on 30 sera, of which 11 were found to contain rubella-specific IgM by both methods. The centrifugation time for the swing-out rotor was 16 hours at 35,000 rpm. This was reduced to 2 hours using the vertical rotor at 50,000 rpm. Routine use of the vertical rotor would allow a reduction in the time taken to perform the test, increase the number of sera tested each time, and reduce wear on the ultracentrifuge.
对用于在蔗糖密度梯度上检测风疹特异性IgM的甩平式和垂直式超速离心机转子的性能进行了比较。对30份血清进行了检测，其中11份血清通过两种方法均检测到风疹特异性IgM。甩平式转子在35000转/分钟的转速下离心时间为16小时。使用垂直式转子在50000转/分钟的转速下，离心时间缩短至2小时。常规使用垂直式转子将减少检测所需时间，每次增加检测的血清数量，并减少超速离心机的磨损。
