Purification of hTREX1WT/WT. (A) SDS-PAGE samples from critical phases in the enzyme purification process. Bands corresponding to various key proteins are identified using 12% polyacrylamide gels. (B) SDS-PAGE gel results demonstrating equal-mass quantities of TREX1 enzymes using 12% polyacrylamide gels. All non-standard lanes contain ~2 μg of protein. Two lanes contain the same human TREX1 wild-type enzyme from different preparations (labeled subscripts “A” and “B”). Note, the TREX1 murine enzyme migrates slightly more slowly relative to the TREX1 human enzyme.
