background: amplification of her2 is seen in 20-30% of breast cancer cases. measurement of her2 gene amplification appears to be of vital importance in planning the treatment schedule for patients with breast carcinoma. the aim of our study was to evaluate her2 amplification status in malignant and benign breast tumors by differential pcr (dpcr). materials and methods: the genomic dna was extra...
BACKGROUND ExCyto PCR cells provide a novel and cost effective means to amplify DNA transformed into competent bacterial cells. ExCyto PCR uses host E. coli with a chromosomally integrated gene encoding a thermostable DNA polymerase to accomplish robust, hot-start PCR amplification of cloned sequences without addition of exogenous enzyme. RESULTS Because the thermostable DNA polymerase is sta...
Aptamers, or single stranded oligonucleotides, are produced by systematic evolution of ligands by exponential enrichment, abbreviated as SELEX. In the amplification and regeneration step of SELEX technique, dsDNA is conversed to ssDNA. Asymmetric PCR is one of the methods used for the generation of ssDNA. The purpose of this study was to design a random DNA library for selection of aptamers wit...
