Cellular Retinoic Acid-Binding Protein in Human Lung Carcinomas2

Abstract
Cellular retinoic acid-binding protein (CRABP) was detected in the cytosol of 11 human non-small-cell lung cancer specimens. Neither normal lung nor a small-cell lung cancer specimen contained this binding protein. The quantity of CRABP per milligram of cytosol protein ranged from 48.3 to 426.5 fmol.
