A pdf protcol on telomerase TRAP assay. (Lorel Colgin, Children's Medical Research Institute, Australia)
The TRAP assay is described in Kim et al. (1994), Science 266: 2011-2015, except that there is no incorporation of radioactive nucleotides nor end-labelling of primers • Principle: the assay measures enzymatic activity of telomerase if it is present. The M2 primer (also known as TS) acts as a substrate for telomerase-mediated addition of TTAGGG repeats. Addition of the repeats occurs at 25ˇăC, after which PCR is used to amplify the extended products. The M2 primer serves as forward primer while CX is the reverse primer for PCR. The products are then electrophoresed on a polyacrylamide gel, which is then stained with Sybergreen (Molecular Probes) to visualize the 6 bp ladder.

telomeres=bits of cell that get shorter every time cell divides. so im thinking shoelaces; each pair pf shoes, you cut laces in half to lace up a new pair, OK? after N new pairs, laces to short to tie any more --- > no more new shoes ... so the problem with cells just dividing forever would cause cancer? im guessing .. yes .. thanx Emma |
