Abstract

In this preliminary report nonradioactive digoxigenine — based and radioactivein situ hybridization procedures for the localization of acetylcholinesterase mRNA were tested and compared in rat brain. General patterns ofAche mRNA localization observed by both techniques did not differ significantly and were practically the same as reported in previousin situ studies on the mammalian brain. Shorter procedure time and avoidance of precautions necessary at work with radioactive materials are major advantages of nonradioactive technique. Under-and over- staining can be prevented by direct examination of coloring reaction. Faint staining in the control experiment with heterologous DNA suggests that proper stringency is essential for the specificity of staining.
