Effects of TER 180 Rz expression on telomerase activity and telomere lengths. (A) Analysis of telomerase activity by telomeric repeat amplification protocol (IC, TRAPeze kit internal control band). Lanes: 1, pooled vector; 2, pooled ribozyme; 3, ribozyme clone 5. (B) Southern blotting analysis of telomere lengths in pooled vector, pooled ribozyme, and ribozyme clone 5 cells. Lanes: 1, ladder of size markers; 2, pooled vector; 3, pooled ribozyme; 4, ribozyme clone 5 transformants.
