title: Two different aldolase A mRNA species in rat tissues.
abstract: Double-stranded DNA was synthesized with reverse transcriptase from size-fractionated poly(A)-containing RNA from rat ascites hepatoma cells. The cDNA was introduced into Escherichia coli HB101 using pBR322 DNA as a cloning vector. Several plasmids containing aldolase A cDNA were identified by colony hybridization with 32P-labeled cDNA prepared from immunologically purified aldolase A mRNA. The partial amino acid sequence of the cDNA sequence was determined, and found to coincide with that of rabbit aldolase A. Using aldolase A cDNA as a hybridization probe, the aldolase A mRNA concentrations in various rat tissues were analysed, and two aldolase A mRNA species differing in nucleotide length were found; the smaller mRNA (about 1550 nucleotides) in muscle, and the larger one (about 1650 nucleotides) in brain and hepatoma cells.
