Publisher Summary Within cells, retinol and retinoic acid are associated with specific
intracellular retinoid-binding proteins: cellular retinol-binding protein (CRBP) and cellular
retinoic acid-binding protein (CRABP). These two immunologically distinct proteins appear
to be the most widely distributed of the intracellular retinoid-binding proteins, having been
reported to be present in all rat tissues examined. The greatest sensitivity and specificity for
measuring either CRBP or CRABP levels, within tissues or cells, have been obtained …
