High-Efficient Transient Gene Transfection for Transcriptional Activity Assay Using Rice Protoplasts on Large-Scale Platform

Transient gene expression in protoplasts offers a straightforward and efficient approach for investigating gene function. Here, I introduce a method that utilizes a 96-well plate format to assess transcriptional activation capacity of transcription factors through transient expression system in rice protoplasts. This method includes plant cultivation, protoplast preparation, transfection, and transactivation assay and allows for the simultaneous measurement and validation of 23 samples with 4 replicates per sample at a time.
