Hydroxyproline assay principle
WebIn the hydroxyproline assay, it is necessary to correct for carryover of the proline oxidation product Δ 1s-pyrroline into the pyrrole extract (see Fig. 2). This is measured in blank … WebThe assay is simple and results in a chromogen with an absorbance maximum at 570 nm. The assay is developed to measure hydroxyproline in acid tissue and/or protein hydrolysates in such a way that it doesn’t need the drying step following acid hydrolysis of collagen for which often special equipment is needed.
