Name: NIA Mouse Neural Stem Cell (Undifferentiated) cDNA Library (Long) Library ID: 1986 Organism: Mus musculus Strain: CD-1 Age: 0 Stage: adult Organ: stem cell Tissue: Neural Stem Cell (Doublets) Host: DH10B Vector: pSPORT1 Vector type: phagemid Insert digest: 5' SalI/NotI 3' Stop Codon Status: without Description: This is a long-transcript enriched cDNA library. Total RNA was obtained from Dr. Angelo L. Vescovi (Institute for Stem Cell Research, Italy). Double- stranded cDNAs were synthesized with an oligo-dT primer (5'- pGACTAGTTCTAGATCGCGAGCGGCCGCCCTTTTTTTTTTTTTTT-3')from 3.8 ug of total RNA, treated with T4 DNA polymerase, and purified by ethanol precipitation. The cDNAs were ligated to Lone-linker LL-Sal4 (5'-AAGAGGTAATCC-3'), purified by phenol/chloroform, and separated from free linker by Centricon 100. The cDNAs were amplified by long-range high fidelity PCR using Ex Taq polymerase (Takara) with primer Sal4-S. The cDNAs were digested with SalI and Not1I enzymes and cloned into SalI/NotI sites of pSPORT1 plasmid vector. The average insert size is about 2.5 kb. The library was constructed by Yulan Piao and Minoru Ko (NIH, NIA). Reference: Genome Res (2001) 11:1553-1558 [PMID: 11544199].
