The AHG itself was also titrated in isotonic saline by a master doubling-dilution technique.
AHG本身也采用等渗盐水双倍稀释滴定测量技术。
Commercial companies took over much more of the AHG market, and the reagent became extremely avid and much more specific.
商业公司接管了大部分AHG市场，试剂的需求日益增大，而且试剂种类越来越具体。
The raw AHG we used was derived from sheep, some of which, I was told, were so old that they had to be fed parenterally (again, I may have been fooled into believing this by naivety).
