In spite of a number of examples of the apparently successful application of the two-
wavelength method of microspectrophotometry to biological materials, a demonstration of …

In connection with the potential development of automatic two-wavelength
microspectrophotometry, a new version of the two-wavelength method has been formulated …

The calculations required for two-wavelength measurements are time consuming and
laborious. In order to circumvent this limitation of the method, a set of tables which combined …

The two-wavelength method of microspectrophotometry corrects for distributional error and
measures the amount of absorbing material by taking advantage of certain spectral …

Because of the absence of suitable standards, microspectrophotometry suffers from a lack of
objective verification. An approach to this problem is suggested which is based on the …

Microphotometry can be applied with advantage to a wide variety of biological problems. In
almost any histological preparation where pigments occur, either naturally or induced by …

I It-N u ra microspectrophotometric work for quantitative purposes the measuring instruments
must fulfil a large number of requirements. These have been described earlier (1). Hitherto …

An apparatus is described in which spectra of microscopic objects can be continuously
scanned. An adjustable linear spiral slit rotated at 2 rps provides an oscillographic …

An experimental review of the Feulgen and gallocyanine-chrome-alum stains for quantitative
cytophotometry of DNA in tissue sections yielded information on the preparation and …

THE study of various problems with ultramicrospectrographic procedures very often
necessitates the determination of the total content of a whole cell of a certain light absorbing …
