{Reference Type}: Journal Article {Title}: A Model of Linear Response with Progressive Decay Equally Suited for RiboGreenĀ® Quantitation of RNA and Dissolution of Solid Oral Dosage forms. {Author}: Klein LJ;Gaye S;Crawford M; {Journal}: J Pharm Sci {Volume}: 0 {Issue}: 0 {Year}: 2024 Jul 4 {Factor}: 3.784 {DOI}: 10.1016/j.xphs.2024.06.019 {Abstract}: A new regression model is presented which offers flexibility, freedom from subjective determinations of linear range, and very wide applicability to measurement systems of industrial importance. This "progressive decay" model starts as a deceptively simple ordinary differential equation. We show here that its solution faithfully describes real but seemingly unconnected data from a plate-based assay for quantitation of RNA with RiboGreenĀ® and dissolution data for a triple fixed-dose combination solid oral dosage form.
