WebA UV hyperchromicity assay was used to assess binding of polylysine to DNA. Increasing quantities of PDL or modified polylysine were added to 6 pg plasmid DNA in 1 .O ml HBS while monitoring absorbance at 260 nm. WebKinetic parameters of the DNase I variants were determined using a Kunitz-based hyperchromicity kinetic assay ( 18) ( see Subheading 3.2.1. ). A colorimetric DNA-methyl green assay ( 19) was used for high-throughput screening of cell-culture supernatants ( see Subheading 3.2.2. and Fig. 2 ).
Hyperchromicity is the increase of absorbance (optical density) of a material. The most famous example is the hyperchromicity of DNA that occurs when the DNA duplex is denatured. The UV absorption is increased when the two single DNA strands are being separated, either by heat or by addition of denaturant or by increasing the pH level. The opposite, a decrease of absorbance is called hypo…
