ELF2 and familial pancreatic carcinoma: To assess if ELF2 is enriched at rs13303327 in an allele-preferential manner in the context of the native DNA, we performed chromatin immunoprecipitation followed by quantitative PCR (ChIP-qPCR) in two pancreatic cancer cell lines heterozygous at this SNP (Hs766T and SW1990).
