Re: hydroxyproline assay to determine collagen content

... NaOH (2N final conc) at 120 degree C for 20 min. To this add 450ul of Chloramine T and oxidise at RT for 25 min. 500ul Ehrlich's reagent added and chromophore developed by incubating at 65 deg for 20 min. Absorbance was read at 550nm. I did not try the authors yet. stip

Another new blue light receptor...?

... peaks in the green (575 nm) and the red (675 nm) regions. The action spectrum suggests that a blue/UV-A light photoreceptor with a flavin-based chromophore participates in the HL response of Lhl4 gene expression. However, the hypersensitivity to near UV-B light suggests the involvement of an ...

Chromophores are atomic configurations which can alter the energy in delocalised systems. They are composed of atoms joined in a sequence composed of alternating single and double bonds. Double bonds in organic compounds can ...

The Fiber Disease

... M. Sugihara, V. Buss* The absorbance of the visual pigment rhodopsin has been calculated with high precision by using the CASPT2 platform for the chromophore and a natural population analysis for the charges of the amino acids that line the protein pocket. Of the three factors generally assumed ...
