Identification of a fetal exon in the human fast troponin T gene.

abstract：:The exposure of cells for 60 min to a serum free medium at ice temperature followed by a return to normal culture conditions (30 min at 37 degrees C) caused a dramatic decrease in NAD+ levels. This decrease in NAD+ was prevented by 3-aminobenzamide. Alkaline elution analysis of DNA from cultures that were sisters to t...
