Stringency

stringency

(Science: molecular biology) reaction conditions, notably temperature, salt, and pH that dictate the annealing of single-stranded DNA/DNA, DNA/ rNA, and RNA/RNA hybrids. at high stringency, duplexes form only between strands with perfect one-to-one complementarity, lower stringency allows annealing between strands with some degree of mismatch between bases.

Re: Morpholino review: how to knockdown

... It is sometimes possible to overcome off-target interactions by raising the incubation temperature of cells or embryos, increasing the stringency of the oligo hybridization (control cells or embryos must, of course, be incubated in similar conditions). Enough about the technology. Your ...

glucose transporters

... the relative abundance of the complementary sequences present in the samples (target) under study. This is done by hybridizing the two under high-stringency conditions and then detecting the sequences of the sample, which consist of a mix of either cRNA or cDNA commonly fluorescently labelled. ...

Ni-NTA-Columns

... of 50 kDa under native conditions. I use the columns of qiagen. Now I have the problem that my protein elutes with contaminants. I increased the stringency of the binding and washing buffer and eluted the last time with 200mM Imidazol in the first step and with 350 mM Imidazol in the second elution ...

Are my answers right?

... and are hard to interpret. • To overcome this problem, a sliding window is used for which only a proportion of the residues have to match (the stringency). For example, for a DNA repeat one may use a sliding window of 23 bases of which only 21/23 bases need to match to generate a point on the ...
