| Research Abstract |
We previously demonstrated the presence of cellular retinoic acid binding protein II, chick-CRABP II, in chick embryos. In the present study, we investigated the distribution of chick-CRABP II in 14-day chick embryos by means of immunoblot analysis. Chick-CRABP II was expressed in skin, muscle, bone with tendon of the embryos, but not expressed in the nervous system. In adult chick tissues, chick CRABP II was not detected on immunoblotting; Chick-CRABP II in adults amounts to less than long/mg soluble embryonic protein involved in the development of specific tissues, such as bone, muscle and skin.
