“…Catalase has proven as a possible agent to support the intracellular drug delivery (Siwale et al, 2009) a biosensor for the determination of alcohol (Hnaien et al, 2010), and can be used in an assay for the quantification of cholesterol (Robinet et al, 2010). The enzyme has been purified and characterized from a wide range of organisms like plants, such as tobacco, van apple, parsley and black gram (Garcia et al, 2000;Yoruk et al, 2005;Lokman et al, 2007;Kandukuri et al, 2012), liver of many mammals like goat (Chatterjee et al, 1989), dog (Nakamura et al, 2000), bovine (Prakash et al, 2002), and from bacteria (Zamocky et al, 2011). Most of the literature reports describe the purification of enzyme through selective ammonium sulphate precipitation and chromatographic techniques like gel-filtration chromatography (Goyal and Anjan, 2008), ion-exchange chromatography based on CM (carboxymethyl) Sephadex, DEAE (diethylaminoethyl) Sephadex or DEAE cellulose (Aydemir and Kuru, 2003;Bilal et al, 2006).…”
