IPTG is combined with X-GAL to detect lac+ colonies or cells in a
colorimetric assay. Distinguishes recombinants (white) from non-
recombinants (blue) in cloning strategies using vectors such as Lambda-11,
M13mp 18 and 19, pUC18 and 19, pUR222 containing the lacZ gene.

PBFI is a UV-excitable, ratiometric green indicator for intracellular potassium (K+) measurements. Ex/Em: 340/505 nm can be used to measure K+-bound PBFI, and Ex/Em: 380/505 nm can be used to detect K+-free PBFI. It is 1.5X more selective for K+ over Naand works well in cytosolic conditions where [K+]/[Na] is ~10. Ratiometry is optimal for imaging applications where quantification of intracellular K+ concentrations is desired and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.
