Figure 5From: Transcriptional control by two leucine-responsive regulatory proteins in Halobacterium salinarum R1Northern analysis of the lrpA1 transcript level. The upper panel represents 16S and 23S rRNA bands on a 1% agarose gel after ethidium bromide staining. The lower panel displays detected transcripts (429 kb; marked by an arrow) using a probe against lrpA1. H. salinarum R1 wild type cells were grown in complex media and harvested at the indicated OD-values.Back to article page
