Retinoic Acid Receptor beta Transcription Factor Activity Assay

Assay Genie's Retinoic Acid Receptor beta (RARβ) Transcription Factor Activity Assay measures the DNA-binding activity of the RARβ nuclear receptor to retinoic acid response elements (RARE) immobilized on the plate. The colorimetric microplate readout captures transcription factor occupancy from nuclear and cell lysates, supporting studies of retinoic acid signaling, gene regulation, and nuclear receptor pharmacology. The kit is validated for reactivity with human, mouse, and rat samples, and is supplied with reagents sufficient for 96 Assays. Researchers commonly apply this assay to investigations in oncology, where RARβ functions as a tumor suppressor in breast, lung, and prostate contexts, as well as in developmental biology and endocrinology research. For nuclear extract preparation, aliquot samples and store lysates at -80°C to preserve transcription factor activity; limit freeze-thaw cycles to maintain binding competence across experimental replicates.
