Darkfield Illumination - http://microscopy.fsu.edu/primer/techniques/darkfield.html

Category: Microscopy Protocols: Optical Microscopy Protocols

The visibility of the faint star light is enormously enhanced against a dark background. This principle is applied in darkfield (also called darkground) microscopy, a simple and popular method for making unstained transparent specimens clearly visible. Such objects often have refractive indices very close in value to that of their surroundings and are difficult to image in conventional brightfield microscopy. - [Read Darkfield Illumination]

Category: Reporter Gene Assays: GFP Assay Protocols

Green fluorescent protein is commonly used to monitor gene expression and protein trafficking within intact cells. The Monster Green® Fluorescent Protein is encoded by an improved synthetic version of the green fluorescent protein gene originally cloned from Montastrea cavernosa (Great Star Coral). - [Read Monster Green® Fluorescent Protein Assay]

DNA Fragment Purification from Polyacrylamide Gels Protocol

A simple protocol for the purification of DNA fragments from Polyacrylamide Gels.

DNA Ligation Protocol

The DNA Ligation protocol described here contains the steps required to join together using ligase enzyme both plasmid DNA and insert DNA fragments in order to create a new plasmid. This new ligated plasmid can be transformed after into competent bacteria to produce DNA for mini, midi or maxi-prep isolation.

Picking Transfected ES Cell Clones Protocol

This protocol a protocol on how to generate transfected embryonic stem (ES) cell clones. The previous protocol in this series is the Protocol for Electroporation of ES cells. The next protocol in the series is the Protocol on Disaggregation, Expansion, and Freezing of Transfected ES Clones.

Vector Design Protocol for Transgenic Mice Generation

The protocol gives general considerations for the design of targeting vectors for transgenic mice. The protocol shares tips in the design of knock-out and knock-in vectors and some of their strategies for producing homologously recombined embryonic stem cells.
