(A) RNA was extracted from tissue biopsy samples obtained at the indicated time intervalls after death at routine postmortem examinations. A total of 10 μg total RNA was separated on a 1.1% agarose gel with formaldehyde and stained with ethidium bromide (0.5 μg/mL). Below the gel the values from EPO mRNA quantitation (in amol per microgram of total RNA) by competitive PCR are given. (B) RNA extracted from tissue samples of different organs taken 4 days after death was run on an agarose gel as described for (A).
