The RUBY Reporter
RUBY is a synthetic gene that encodes the enzymes for the synthesis of betalain, a vivid red natural product. RUBY is a great reporter for monitoring transformation events and gene expression levels because transgenic cells are distinctly red and visible to the naked eye. It does not require special equipment, expensive chemicals, or invasive treatments.
