AFLP® technology was developed initially by Keygene in the early 1990’s. AFLP has become a widespread genetic fingerprinting technology.

The starting material for de novo isolation of stem cell lines can be either normal 3.5-days post coitum (dpc) expanded blastocysts or "delayed" blastocysts. Delayed blastocysts are usually collected 4-6 days after ovariectomy. For both groups of blastocysts, tissue culture procedures are similar. The only difference is the timing of the first disaggregation, because delayed blastocysts will initially grow more slowly. - [Read De Novo Isolation of Embryonic Stem (ES) Cell Lines from Blastocysts Protocol]
There are several manual methods that can be used to perform tissue microdissection. Techniques using hand-held tools as well as mechanical micromanipulator-based approaches have been described. However, speed and precision are the most important parameters and any method that achieves these is adequate. Investigators should also expect to invest time initially by practicing on 10 to 20 cases to begin to feel comfortable with the technique. - [Read Manual Microdissection]
Plasma membranes are isolated from the yeast Saccharomyces cerevisiae. The cell wall is initially digested by helicase, followed by hypoosmotic lysis and homogenization. Membranes are prepared by subsequent differential centrifugation. The activity of the H+-ATPase is then determined by measuring the amount of inorganic phosphate released from ATP. - [Read Yeast Plasma Membrane H+ -ATPASE Toxcity Test Protocol]
