[Molecular forms of acetylcholinesterase in the slow muscle and the fast muscle of the chicken]. 1978

J Koenig, and M Vigny

Five molecular forms of AChE are present in the slow (ALD) and twitch (PLD) muscles of the chick. These forms have 4 S, 7 S, 11 S, 15 S and 20 S sedimentation coefficient in sucrose gradient. The heaviest forms, the 20 S and 15 S of AChE are absent in uninnervated muscles and present in innervated muscles. In innervated muscles, the 20 S and 15 S AChE are present in both nerve-free segments and end-plates zones. The 20 S and 15 S which are not specifically associated with the end-plate zones in the chick could be considered as a biochemical "marker" of neuromuscular interactions.

D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick
