Abstract
The invention relates to derivatives of fluorescein and to their production. The compounds are of value in determining the intracellular pH. Thus there may be obtained fluorescent living cells with a comparatively stable level of fluorescence. The novel fluorescein compounds can be used for other labelling purposes in biology and biochemistry.
