Fig. 2From: Correlation of alteration of HLA-F expression and clinical characterization in 593 brain glioma samplesIHC staining of HLA-F in different grades (a): upper, × 20; lower, × 40. Analysis of HLA-F protein expression (semi-quantitative scoring, expression intensity × expression area) indicated that HLA-F protein expression is higher in high-grade samples (b)Back to article page
