Abstract
We have developed a purification method for the isolation of platelet-specific poly (A+) RNA and demonstrated that human blood platelets, despite the absence of a nucleus, contain stable mRNA. The poly (A+) RNA was used to construct a platelet- specific cDNA expression library in λgtll. The platelet derivation of the purified mRNA was confirmed by identification of membrane glycoprotein Ib (GPIb) message by immunoprecipitation of rabbit reticulocyte lysate translation products with poly- and monoclonal antibodies against GPIbα and by sequencing of a GPIbα cDNA clone
