PG - 4547-55 AB - The isolation and translational properties of rat immunoglobulin E (IgE) heavy chain mRNA are described. The mRNA has a sedimentation coefficient of approximately 18S, a chain length of about 2000 nucleotides and directs the synthesis in vitro of a polypeptide of 65000 molecular weight in an mRNA-dependent rabbit reticulocyte lysate. Inclusion of dog pancreatic microsomes in the cell-free translation system resulted in a heavy chain product of about 75000 molecular weight, presumably as a consequence of glycosylation in vitro. This species co-migrated in an SDS polyacrylamide gel with mature IgE heavy chain. Substantial purification of heavy chain mRNA was achieved by denaturing sucrose gradient centrifugation and agarose gel electrophoresis.
