 Background 
This cDNA library (plasmid DNA) is constructed from human embryonic kidney 293T cell -derived poly(A)+ RNA by the Linker-Primer method by Professor Hi roshi Nojima of Research Institute for Micro bial Diseases, Osaka University. This library is unidirectionally cloned by using the oligo (dT)18 linker primer which contains the restriction enzyme site of Not I, and BamHI (Bgl II)-Sma I adaptor.
The pAP3neo vector used in this library can exp ress human genes in m ammalian cells as it cont ains SV40 promoter. It also contains Ori of pUC plasmid required for replication in E.coli, f1 ori which is necessary for ssDNA synthesis, and bacteriophage T7 and T3 promoters for RNA synthesis. GenBank Accession No. AB003468
 Application 
PCR screening of kno wn or u nknown gene: Prepare the primers for the known or unknown gene (cDNA) and amplify the gene by PCR from this library followed by clonin g to an approp riate vector. It is useful for large-scale protein productions, and preparation of probes, etc.
Standard amplifying conditions: 35 cycles of PCR reactions using 10-100 ng of cDNA as a template. (Change the quantity of template and the number of cycles depending on the expression rate of mRNA of the objective gene.)
