Figure 2: Detection of Telomerase activity in (A) non IBC and (B) IBC tissue samples (1-9). Bottom line represents 36 bp internal controls (S-IC) and ladders represent 6 bp repeats starting with 50 bp. TSR8 quantitation control (Q) is an oligonucleotide, provided with the kit, with a sequence identical to the TS primer extended with 8 telomeric repeats AG(GGTTAG)7. This control serves as a standard for estimating the amount of TS primers with telomeric repeats extended by telomerase in a given extract.
