J C Groppe et al.
Analytical biochemistry, 210(2), 337-343 (1993-05-01)
RNA isolated by conventional guanidinium isothiocyanate methods from tissues of a mollusc (red abalone: Haliotis rufescens) is largely degraded and discolored by contaminants. These contaminants are associated with inhibition of reverse transcriptase, prevent accurate spectrophotometric determination of RNA concentration, and
P Chomczynski et al.
Analytical biochemistry, 162(1), 156-159 (1987-04-01)
A new method of total RNA isolation by a single extraction with an acid guanidinium thiocyanate-phenol-chloroform mixture is described. The method provides a pure preparation of undegraded RNA in high yield and can be completed within 4 h. It is

Having a high folding efficiency and a low tendency to aggregate, the superfolder GFP (sfGFP) offers a unique opportunity to study the folding of proteins that have a β-barrel topology. Here, we studied the unfolding-refolding of sfGFP that was induced

Four protocols for extracting DNA from mites, using phytoseiid species as exemplars, were evaluated to determine whether the DNA obtained could be used to amplify nuclear, mitochondrial or Random Amplified Polymorphic DNA (RAPD) markers from males, females and eggs. Protocol
