Amplification and characterization of a beta-globin gene synthesized in vitro

Full-length, double-stranded globin DNA was synthesized in vitro starting from rabbit globin mRNA. Several restriction endonuclease cleavage sites with known recognition sequences were mapped on this DNA as a means of assessing the accuracy of in vitro synthesis

End labeling of enzymatically decapped mRNA.

A method is presented for rapid and efficient 5' end labeling with 32P of capped mRNAs, by a series of three enzymatic reactions: the blocking nucleotide of the cap structure is removed by tobacco acid pyrophosphatase, and after dephosphorylation with alkaline phosphatase the 5' end is labeled with gamma-32-P-ATP and T4 polynucleotide kinase
