High JAK2 Protein Expression Predicts a Poor Prognosis in Patients with Resectable Pancreatic Ductal Adenocarcinoma

Figure 2

Intensity of JAK2 expression in PDAC tissue by immunohistochemistry. Positive expression is shown by brown-yellow particles distributed in the cell membrane and cytoplasm (SP staining ×50). The cellular staining was classified using a scale of 0-3 as follows: (a) 0 = negative, (b) 1 = weakly positive, (c) 2 = moderately positive, and (d) 3 = strongly positive.
