Category: Stem Cell Protocols: Stem Cell Isolation Protocols

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]

Category: Stem Cell Protocols

This protocol decribes derivation of TS cell lines from 3.5-days post coitum (dpc) mouse blastocysts. The procedure is similar to the derivation of embryonic stem (ES) cell lines. However, the success rate is considerably higher, and less expertise is required to recognize pluripotent TS cell colonies. - [Read Derivation of Trophoblast Stem (TS) Cell Lines from Blastocysts Protocol]

Category: Plant Biology Protocols: Plant Genetics Protocols

Microsatellite markers, also referred to as STMS (SequenceTagged Microsatellite Sites) or STR (Short Tandem Repeats) are widely used as molecular markers for intraspecific genotyping, molecular mapping and breeding purposes. The method described is an efficient,fast and relatively inexpensive way to obtain microsatellite markers without post-cloning selection methods. So far, the method has been successful in onion (Allium cepa L.), a plant with a large genome and for pathogenic fungi. - [Read Enrichment for Microsatellite Sequences in Onion (Allium cepa L.)

Category: Plant Biology Protocols: Plant DNA RNA Isolation Protocols

A. thaliana has a very small haploid genome and this makes obtaining DNA somewhat difficult. The most notable problem is that DNA is usually contaminated with polysaccharide which inhibit restriction enzymes as well as other DNA modifying enzymes. This problem is most easily solved by using young plants which have not accumulated as much polysaccharide as older plants. The best results are obtained with plants that are two to three weeks post germinated. - [Read Plant DNA Extraction Protocol]
