Abstract
The mRNA coding for the small apo-Very Low Density Lipoprotein (apo-VLDLII) from chicken serum was highly enriched by oligo(dT) chromatography and preparative gel electrophoresis of estrogenised liver RNA. Double-stranded cDNA was synthesised by the subsequent actions of reverse transcriptase and DNA polymerase, and used for a preliminary characterisation of the structural gene. Molecular cloning of dC-tailed ds-cDNA into the Pst I site of plasmid pBR 322 yielded several recombinant clones. Five chimeric DNAs were selected and characterised by restriction enzyme mapping and electron microscopy of R-loops. At least two of them (pVLDLII 3.33 and pVLDLII 4.82) contain an almost full-length ds-transcript of VLDLII mRNA in which no more than 10-20 bases at the 5'- end are missing.
