(A) Schematic drawing of detection of newly transcribed RNAs in S. cerevisiae cells by the MTSEA biotin-XX detection system. (B) Total RNAs from the samples without addition of s4U (left lane)- and with addition of s4U (right lane) were separated by 10% PAGE (7 M urea). The gel was stained with methylene blue. 4-Thiouridine in total RNAs was detected by the MTSEA biotin-XX system.
