Nkx6.2 synergizes with Cdx-2 in stimulating proglucagon gene expression

Figure 1 The sliver staining of SDS-PAGE for eluates from GST or GST-Cdx-2 column with cell lysate of GLUTag or InR1-G9. GSH: Elution was performed by a buffer containing 50 mmol/L glutathione; SDS: Elution was performed by 1 × Laemmli SDS containing sample buffer. The arrows indicate the position of Nkx6.2. GST: the control GST protein; Cdx: Cdx-2/GST fusion protein.
