PARP14 and lymphoma: To directly assess and quantify its binding to the PARP14 promotor, we performed cross-linked chromatin IP for 3x Flag of IL-4 stimulated lymphoma cells (OCI-Ly8) stably expressing either 3x Flag-tagged STAT6MUT (D419G) or 3xFlag-tagged STAT6WT followed by quantitative PCR for the PARP14 promotor region.
