Detection of HPV DNA using MY09/11 primers in esophageal carcinoma samples. M was 100 bp DNA ladder; Neg was a negative control; lanes 1–7 were detection of HPV DNA in different esophageal carcinoma samples. HPV16 and 18 were positive controls with the HPV16/pBR322 and HPV18/pBR322 templates. b Detection of HPV16 DNA using HPV16 E6 specific primers in esophageal carcinoma samples. M was 100 bp DNA ladder; Neg was a negative control; lanes 1–7 were detection of HPV16 DNA in different esophageal carcinoma samples. HPV16 was a positive control with HPV16/pBR322 template; HPV18 was a specific control using HPV18/pBR322
