Figure Lengend Snippet: Electromobility shift assays (EMSAs) suggest that rs61746197 A > G is a functional SNP. ( A ) Ten micrograms of unstimulated nuclear extract from K562 cells was incubated with reference (Ref, R) or alternative (Alt, A) probe as indicated. Cold Ref probe titrates signal away from Alt at a lower stoichiometric ratio than the converse (arrow and compare lanes 11 – 13 with 6 – 8 ). ( B ) Unstimulated extract ( left panel, U) exhibits a markedly stronger baseline shift than TPA stimulated extract ( right panel, S). Unstimulated nuclear extract (U) when incubated with labeled alternative probe (A) produces a novel secondary shift not observed with either the reference probe (R) or the TPA stimulated extract (S). Addition of RelA–p65 antibody abrogates this secondary shift (arrow).
