Various whole cell extracts (30 μg) were separated by 7.5% SDS-PAGE, and the membrane was blotted with DNA polymerase iota antibody [HL3115] (GTX640591) diluted at 1:1000. The HRP-conjugated anti-rabbit IgG antibody (GTX213110-01) was used to detect the primary antibody, and the signal was developed with Trident ECL plus-Enhanced. Corresponding RNA expression data for the same cell lines are based on Human Protein Atlas program.
