FRP mRNA expression in normal human adult and embryonic tissues, and in cultured cells. Blots containing ≈2 μg of poly(A)+ RNA from each of the indicated tissues or 10 μg of total RNA from different human cell lines were probed with radiolabeled FRP and β-actin cDNA fragments, as described in the Methods. The position of DNA size markers, expressed in kb, is indicated at the left of the tissue blots; the position of 28S and 18S ribosomal RNA is shown at the left of the cell line blot.
