Analysis of DNA Fragmentation Using Agarose Gel Electrophoresis (Subscription Required) - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4429

Category: Cell Biology and Cell Culture: Apoptosis Protocols: Apoptosis Analysis

Analysis of DNA Fragmentation Using Agarose Gel Electrophoresis Shailaja Kasibhatla et al. This protocol provides a qualitative method for assessing cell death by detecting DNA fragments using agarose gel electrophoresis. One of the classic features of apoptosis is the cleavage of the genomic DNA into oligonucleosomal fragments represented by multiples of 180-200 bp. Visualizing these fragments can aid in characterizing an apoptotic event. May be combined with more quantitative methods. - [Read Analysis of DNA Fragmentation Using Agarose Gel Electrophoresis (Subscription Required)]

Category: Primary Cell Isolation and Culture Protocols: Laser Capture Microdissection Protocols

Human tissues are comprised of multiple interacting cell populations in a complex three dimensional arrangement with each cellular phenotype determined by a unique profile of mRNA and protein expression. Before microdissection techniques were developed, the only analysis tools for phenotypic studies were primarily immunohistochemistry and in-situ hybridization. While useful, these tools are limited to single gene analysis and, in general, do not allow qualitative studies. - [Read Microdissection Overview]

Negative Stain Electron Microscopy of Microtubules Protocol - http://mitchison.med.harvard.edu/protocols/EM.html

Category: Cytoskeleton Protocols: Microtubules Protocols

Negative staining is a rapid, qualitative method for analyzing microtubule structure at the EM level. Because negative staining involves deposition of heavy atom stains, structural artifacts such as flattening of the cylindrical microtubule and opening up of microtubules into flat sheets are common. Negative staining is very useful because of its ease, rapidity and lack of requirement for specialized equipment other than that found in a regular EM facility. - [Read Negative Stain Electron Microscopy of Microtubules Protocol]
