For the telomeric repeat extension of oligonucleotide, 20 μL of
telomerase extracts were mixed with 20 μl of extension reaction
mixture (provided with the kit) and incubated at 30 °C for 30 min. The
tissue extracts were used without dilution (Table 1). The elongation
products were purified and precipitated with ethanol. These elongation
products were then amplified by PCR.
