From Old Protocols Page
Labeling DNA for single-molecule stretching
Various methods to label dsDNA with digoxigenin (dig) and biotin for end-to-end stretching.
- PCR with labeled primers
- klenow fill-in
- ligating labeled duplexes (or hairpins)
- ligating multiply-tagged segments.
- (Useful for a couple of the above protocols): Koch Lab:Protocols/Oligonucleotide Annealing
Labeling DNA for unzipping
More complicated construction of a molecules that will unzip when stretched, as in our 2002 Biophys. J. paper PMID 12124289. Compared with DNA stretching, making a construct for unzipping presents many more potential pitfalls, and it is also challenging to get good yield.
- Creating dig / biotin unzipping constructs for unzipping long DNA segments
- Hybridized unzipping forks
DNA tethering
Making single-molecule tethers via antidig-dig and biotin-streptavidin. Including all the tricks for washing glass, blocking, how much DNA to use, microsphere selection, microsphere preparation, etc.
Probing protein-DNA interactions by unzipping single DNA molecules
Detailed protocols for "popping" experiments -- that is, unzipping DNA molecules with DNA-binding proteins present
Single-molecule manipulation buffers
Various buffers used in single-molecule manipulation experiments
Instrumentation protocols
- Preparing a low-tech (coverglass, slide, double-stick stape) sample chamber
- Flow cells for electromagnetic steering of microtubules labeled with magnetic microspheres.
- Placing single 3 micron magnetic microspheres (or also 30 micron polystyrene) onto MEMS devices (with micromanipulators) as in 2006 Appl. Phys. Let. (PDF)
- Making a flow cell to hydrate a SUMMiT MEMS device
- Some things about AODs
Microfluidics protocols in Lopez Keck lab/Koch lab
- For specific protocol see the following link
- Photo lithography
- PDMS
