摘要: Publisher Summary This chapter presents chloramphenicol acetyltransferase (CAT) as a gene expression tool, the system has been widely employed to characterize transfection techniques for tissues and cell lines, characterizing DNA mutagenesis repair systems, genetic biochemical analyses of transcription factors initiation complexes, characterization signaling pathways, tissue specificity promoters in transgenic animals, evaluating efficacy delivery systems therapy intact animals. The focuses on three types CAT assay methods, thin-layer chromatography (TLC) assay, mixed phase high-performance liquid (HPLC) assay. Parameters that can influence sensitivity reproducibility assays include concentration stability reagents, temperature reaction, reaction time, extraction efficiency products solvents, presence other acetylases volume, type transfected, preparation extracts, amount extracts used reaction.
