Schematic structure of DEAE-C: positively charged diethylaminoethanol groups can bind negative ions. Diethylaminoethyl cellulose (DEAE-C) is a positively charged resin used in ion-exchange chromatography, a type of column chromatography, for the separation and purification of proteins and nucleic acids.
A solution of para-anisaldehyde in acid and ethanol is a useful stain in thin layer chromatography. [4] Different chemical compounds on the plate can give different colors, allowing easy distinction. DNA breakage
it is an ingredient in Photo-Flo, a solution used in photographic processing to prevent minerals from water being deposited on the film after drying. Apart from laboratory use, Triton X-100 can be found in several types of cleaning compounds, [ 7 ] ranging from heavy-duty industrial products to gentle detergents.
OPA is used in a very sensitive fluorogenic reagent for assaying amines or sulfhydryls in solution, [6] notably contained in proteins, peptides, and amino acids, by capillary electrophoresis and chromatography. OPA reacts specifically with primary amines above their isoelectric point Pi in presence of thiols.
