===Labeling DNA for single-molecule stretching===
Various methods to label dsDNA with digoxigenin (dig) and biotin for end-to-end stretching.
* [[/Dig-bio PCR|PCR with labeled primers]]
* klenow fill-in
* ligating labeled duplexes (or hairpins)
* ligating multiply-tagged segments.
** (Useful for a couple of the above protocols): [[/Oligonucleotide Annealing|Oligo 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.

===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.

This page is under construction.


One of the goals of our lab is to share protocols in a form that makes it as easy as possible for other labs to build off of them. These will be a combination of protocols that we will develop and also those that Steve has developed in the past but has not had a good opportunity to distribute yet. If any of the following protocols are of particular interest, drop us a line or make a note on the discussion page! We also want to share software applications and computational modules (mostly LabVIEW) that would be useful to others.

General Lab Techniques

Every lab has its own standards when it relates to lab safety, cleanliness, and shared equipment protocols. Below we've documented our specific techniques with regards to these general lab standards:

Molecular Biology Protocols

Standard Techniques

  • PCR
  • Gel Electrophoresis
  • Cloning
  • Transformation into E. Coli

KochLab Techniques

Equipment Setup

Computational Protocols

  • Shotgun DNA Mapping
  • Kinesin Processivity
  • Kinesin Tracking
  • Motion Detection Camera
  • Loading Rate Clamp
