Isolation and characterization of human liver mRNA.

Poly(A)-RNA isolated from human liver shows a predominant size in the 18 S region. It can be translated into a broad range of proteins up to molecular weights of more than 100 000 with predominant translation products in the 45 000-55 000 region. Full length cDNA has been transcribed and used for a complexity analysis of this mRNA giving a total sequence complexity of about 7 000 different mRNA species.
