Bradford Protein Assay Spectrophotometry - http://homepages.gac.edu/~cellab/appds/appd-g.html#exG-1

Category: Protein Protocols: Protein Quantitation Concentration Protocols: Bradford Protein Assay Protocols

Bradford Protein Assay Spectrophotometry. Includes spectrophotometry information and the Bradford protein assay: A spectrophotometer or colorimeter makes use of the transmission of light through a solution to determine the concentration of a solute within the solution. A spectrophtometer differs from a colorimeter in the manner in which light is separated into its component wavelengths. A spectrophotometer uses a prism to separate light and a colorimeter uses filters. - [Read Bradford Protein Assay Spectrophotometry]

Fluorometric Quantitation of DNA Using Hoechst 33258 Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4458

Category: Nucleic Acid Detection Protocols

Protocol describes the quantitation of DNA using Hoechst 33258, a fluorescent dye that binds to double-stranded DNA. Fluorometry is simple and more sensitive than spectrophotometry, and allows the detection of nanogram quantities of DNA. The assay can only be used to measure the concentration of DNAs whose sizes exceed ~1 kb, as Hoechst 33258 binds poorly to smaller DNA fragments. - [Read Fluorometric Quantitation of DNA Using Hoechst 33258 Protocol]
