Loss of CDX2 expression is associated with poor prognosis in colorectal cancer patients

Figure 2 Histogram for loss of CDX2 expression using two different anti-CDX2 primary antibodies in immunohistochemistry. A, B: Histogram of CDX2 expression according to CIMP status (A: CDX2-88; B: EPR2764Y); C, D: Histogram of CDX2 expression according to MSI status (C: CDX2-88; D: EPR2764Y). CIMP: CpG island methylator phenotype; MSI: Microsatellite instability; MSS: Microsatellite stable.
