WGM24A52C7WGM24A52C7
aHUVEC obtained from three different primary cultures were stimulated with medium alone or medium containing TNFα (500 U/ml) for 2 h, and surface expression of PR3 was assessed using two anti-PR3 mAb (WGM2 and 4A5), while 2C7 served as an isotype-matched control. Data are expressed as mean fluorescence intensity (MFI). TNFα, tumor necrosis factor-α. Other abbreviations as in Table 1.
