- IN-Gel Hybridization procedure for telomeric single stranded DNA detection (Wellinger Lab, Université de Sherbrooke )
Telomeric DNA is replicated by a special mechanism in which an enzyme called telomerase will elongate a short 3' overhang and create long, single stranded DNA at the ends of chromosomes. This enzyme requires a single stranded DNA portion as its substrate since the telomerase RNA moiety has to anneal with this DNA...

Telomeric Repeat Amplification Protocol (TRAP) Telomerase Assay
(The Science Advisory Board)
This protocol describes a semi-quantitative in vitro assay to detect telomerase activity. Any active telomerase present in a cell extract from detergent-lysed cells will add a variable number of telomeric repeats (TTAGGG) to the 3' end of a substrate oligonucleotide. PCR that incorporates a radiolabeled nucleotide is then used to amplify the extension products. The presence of telomerase in the cell extracts is assessed by the appearance of a ladder of PCR products on a native polyacrylamide gel.
