microspectrophotometry


mi·cro·spec·tro·pho·tom·e·try

(mī'krō-spek'trō-fō-tom' ĕ-trē), A technique for characterizing and quantitating nucleoproteins in single cells or cell organelles by their natural absorption spectra (ultraviolet) or after binding stoichiometrically in selective cytochemical staining reactions, as in the Feulgen stain for DNA.
