±-Amino-³-butyrolactone hydrobromide (±-ABL) is a chemical compound that can be found in chloroform. It is a synthetic activator of mutant strains of the bacterium Escherichia coli. ±-ABL emits light when mixed with chloroform, and this emission can be detected using a spectrophotometer. The emission spectrum of ±-ABL has been shown to have peaks at 510 nm and 530 nm, which correspond to the λmax values for ECL luminescence. This chemical also has the ability to activate mutant strains of E. coli when dissolved in liquid chromatography, and it can be extracted from plates exposed to light.
