HLA-G and non-small cell lung carcinoma: We further explored the reactivity consistency between mAb4H84 (detecting denatured HLA-G heavy chain of all HLA-G isoforms) and mAb 5A6G7 (detecting denatured HLA-G heavy chain of HLA-G5/-G6 isoforms) in 39 case-matched NSCLC lesions with immunohistochemistry.
