Immunohistochemical staining of NIPBL in lung adenocarcinoma. The overall immunohistochemical staining scores could range from 0 to 12. An overall staining score of ≥6 was considered to be high expression of NIPBL protein, score of 0–5 was considered as low expression. Low level of expression of NIPBL in lung adenocarcinoma sample: (A) Absence of nuclear NIPBL expression, overall staining score is 0, (B) overall staining score is 1–2. High level expression of NIPBL in lung adenocarcinoma samples: (C) overall staining score is 6, (D) overall staining score is 8, (E) and (F) overall staining score are 12. Original magnification: ×200.
