The chromatin template activity of the polytene chromsomes in larval salivary glands of Drosophila hydei has been assayed by in situ transcription, on the fixed chromatin using E. coli RNA polymerase holoenzyme and 3H-UTP as the monitoring substrate, both with optimal salt and high salt concentration (1 M NaCl). Results reveal an increase in the net(More)
A rapid method of autoradiography using the scintillation cocktail (Toluene and scintillation fluid, Omnifluor) has been described earlier. Its application and efficiency have been tested using both 3H-thymidine and 3H-uridine. The optimum time required for processing the autoradiograms has been found to be 24 h dry exposure followed by 48 h in the(More)
