Telomerase activity assays. Lanes are labeled as follows: +, telomerase positive human cancer cell line; H, heart; Li, liver, Sp, spleen; K, kidney; Sk, skin; Lu, lung; T, testis. The number below each lane corresponds to relative units of telomerase activity calculated as described in the text. Each gel represents one animal. The reaction includes internal positive control for the polymerase chain reaction (PCR) amplification step (indicated by arrow). Some telomerase negative samples show nonspecific bands of wrong molecular weight caused by unspecific PCR amplification.
