Figure 7. Sp3 present in lens nuclear extracts interacts with the CT box.
The [32P]-end-labeled probe -186/-148 was incubated with lens nuclear extract in the absence or presence of antibodies against Sp1 (lane 4), Sp2 (lane 6), Sp3 (lane 8) or Sp4 (lane 10). The complexes are indicated as C1, C2, and C3. Only the antibody against Sp3 protein completely abolished the formation of C1 and C3 complexes.
