For the production of biotechnological products, expression of therapeutic proteins in E.coli cells is commonly used. Due to which there is a possibility of DNA contamination from the host cells in the products which are manufactured. However, the limit of DNA contamination from the cell lines has been set by regulatory agencies. According to WHO the limit of DNA contamination should not exceed 10 ng/dose in the products manufactured.
The Krishgen E.coli Host Cell DNA Kit is based on the DNA dye binding assay which utilizes PicoGreenP TM Pdye. The DNA samples and the standards are reacted with PicoGreenP TMP dye, which is a DNA intercalator that binds strongly to the double stranded DNA. Upon binding to DNA, PicoGreenP TMP dye fluoresces with an excitation of 485 nm and emission of 525 nm. The intensity of the fluorescent signal is proportional to the quantity of DNA in the standard or the samples.
