Lymphocyte proliferation tests

[FORSDYKE at QUCDN.QueensU.CA]

    Try measuring total RNA. It is very cheap and could be used in the "third
 world". All you need is a bottle of NaOH, a bottle of perchloric acid and
 access to a uv spectrophotometer (hmmm. not so cheap!). The reference is
 Biochem. J (1967) 105: 679 "Quantitative nucleic acid changes during PHA-
 induced lymphocyte transformation in vitro."
