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.

Multiplex amplification of ancient DNA
(Molecular Ecology Group, Max Planck Institute)
This method allows amplification of multiple PCR fragments (in our hands at least about 50) in a single PCR, saving DNA extract and work. We found it to work well for both mitochondrial and nuclear DNA. Ideally, a complete mtDNA genome can that way be amplified in just two PCRs.

- Protocol for Real-Time RT-PCR (Dr. Xiaowei Wang at the Department of Molecular Biology, Massachusetts General Hospital)
This protocol describes the detailed experimental procedure for real-time RT-PCR using SYBR Green I. The procedure begins with reverse transcription of total RNA. The cDNA is then used as template for real-time PCR with gene specific primers. You may need to modify this protocol if you use different reagents or instruments for real-time PCR.

Gene-specific RT-PCR (Cancer Gene Anatomy Project, NCI)
Protocol may be used for amplifying individual transcripts from RNA recovered from microdissected cell populations. The procedure for reverse transcription is as regular RT, but for PCR, radioactive dCTP is used and PCR products are separated by running polyacrylamide gel.

- Semi -Quantitative RT-PCR (Pamela Stanley Lab Wiki, Yale University)
The RT-PCR method can be used not only to detect specific mRNAs but also to semi-quantitate their levels. Thus, one can compare levels of transcripts in different samples. This can be done in two different ways. One is to quantitate against levels of transcripts from a control, house-keeping gene (such as actin and GAPDH). (Transcription of house-keeping genes is believed to be unaffected by almost all experimental conditions.) The second method is to add an exogenous, primer-specific PCR template during PCR.

Ligase independent cloning
(Dr. Arie Geerlof)
Ligase independent cloning (LIC) is a simple, fast and relatively cheap method to produce
expression constructs. It makes use of the 3'--> 5'-activity of T4 DNA polymerase to create
very specific 10-15 base single overhangs in the expression vector. PCR products with
complementary overhangs are created by building appropriate extensions into the primers and
treating them with T4 DNA polymerase as well. The annealing of the insert and the vector is
performed in the absence of ligase by simple mixing of the DNA fragments. This process is
very efficient because only the desired products can form.

- Chromatin Immunoprecipitation from Human Embryonic Stem Cells (Journal of Visualized Experiments)
Chromatin immunoprecipitation involves the purification of in vivo cross-linked chromatin. The isolated chromatin is reduced to smaller fragments by enzymatic digestion or mechanical force. Chromatin fragments are precipitated using specific antibodies to target proteins or protein and DNA modifications. The precipitated DNA or RNA is purified and used as a template for PCR or DNA microarray based assays.
