This cDNA library (plasmid DNA) is constructed from human embryonic kidney 293T cell -derived poly(A)+ RNA by the Linker-Primer method (Ref.1) by Professor Hiroshi Nojima of the Research Institute for Microbial Diseases, Osaka University. This library is unidirectionally cloned 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 express human genes in mammalian cells as it contains a SV40 promoter. It also contains Ori of pUC plasmid required for the replication in E.coli, f1 ori which is necessary for ssDNA synthesis, and bacteriophage T7 and T3 promoters for RNA synthesis (see Figure). GenBank Accession No. AB003468


PCR screening of known or unknown gene: Prepare the primers for the known or unknown gene (cDNA) and amplify the gene by PCR from this library followed by cloning to an appropriate 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 level of mRNA of the particular gene.) 


* This library is to be used only by the purchaser. It is not allowed to amplify and transfer it to a third person.
