A cDNA library was constructed from poly(A)+ RNA from suspension-cultured cells derived from stem tissue. The cDNA synthesis was carried out using an RNase H approach and EcoRI adaptor strategy. The cDNA-adaptor construction was cloned in the EcoRI sites of the expression vector pUC19 and the cDNA library was established by transforming competent Escherichia coli DH5 alpha to produce 2.5 x 105 transformants/ micro g poly(A)+ RNA. The library was screened immunologically with polyclonal antibodies against horseradish peroxidase; 17 positive clones with inserts between 500 and 1500 bp were isolated and sequenced by the chain termination and/or chemical method.
