## Abstract Two hundred and twelve urine specimens, from several clinical groups, were examined for BK virus (BKV) using the polymerase chain reaction (PCR) to detect the VP1 region of BKV DNA. Positive results were obtained on 14 specimens from 44 postβtransplant patients (31.8%), 10 specimens fro

β¦ Synopsis
We have developed a polymerase chain reaction (PCR) method for sequencing of tobacco chloroplast genome. In a mixture containing chloroplast DNA, 5'-end-labeled oligonucleotide primer, Taq DNA polymerase and reaction buffer, we were able to sequence a segment of chloroplast 16S rRNA gene. The results showed that the 750 bp of DNA sequenced were identical to the sequence reported, indicating that direct sequencing method that we have developed is useful for the sequencing of chloroplast genome. To analyze the chloroplast genome more rapidly in those in vitro grown plantlets, we also developed a simple method which is applicable for the amplifications and sequencing of chloroplast 16S rRNA fragment from either 0.15 g of tobacco leaf or stem tissue. The readable sequences obtained from the presented methods were consistent with the published sequence.

A number of different procedures have been developed for direct sequence analysis of PCR products. These methods rely on the cumbersome isolation of specific PCR products from agarose gels or the production of single-stranded template DNAs. In the approach presented here, we describe primers for the
## Abstract The __neu__ gene in rat neuro/glioblastoma was found to be activated by a single point mutation in the DNA sequence encoding the transmembrane region of the __neu__βencoded p185 protein. The human homologue of the rat __neu__ gene, termed cβ__erb__Bβ2 or __HER__β2, can also be activated
## Abstract Two previous studies have reported the presence of human papillomavirus (HPV) genomic sequences in colorectal cancers. We examined DNAs from 50 colorectal tumors for HPV sequences by polymerase chain reaction (PCR), using HPV consensus L1 primers for amplification. The PCR products were
