Assay of vacuolar pH in yeast and identification of acidification-defective mutants.
As part of a genetic analysis of the biogenesis and function of the vacuole (lysosome) in the yeast Saccharomyces cerevisiae, assays of vacuolar pH were developed and used to identify mutantsExpand

The VPH1 gene encodes a 95-kDa integral membrane polypeptide required for in vivo assembly and activity of the yeast vacuolar H(+)-ATPase.
Yeast vacuolar acidification-defective (vph) mutants were identified using the pH-sensitive fluorescence of 6-carboxyfluorescein diacetate (Preston, R. A., Murphy, R. F., and Jones, E. W. (1989)Expand

Astrometric Detection of a Low Mass Companion Orbiting the Star AB Doradus
We report submilliarcsecond-precise astrometric measurements for the late-type star AB Doradus via a combination of VLBI (very long baseline interferometry) and HIPPARCOS data. Our astrometricExpand
