Allgemeine Beschreibung

Wheat germ tRNA contains many different specific tRNA molecules.

Anwendung

Crude transfer RNA (tRNA), purified from wheat germ, contains many specific tRNA molecules that can be separated by different processes. Experiments for detailed investigation of structure and function using in vitro translation systems often require highly purified tRNA, which can be achieved by combinations of chromatographic separations and reversible biochemical modification of the tRNA. Wheat germ tRNA has been used for the purification of RNAse Z (tRNA 3′- processing endonucleases) from wheat germ. The purification included six steps with the most efficient one using an affinity column made of wheat germ tRNA, which the RNAse Z bound tightly.
Suitable for use as a carrier in nucleic acid purification and precipitation.

Komponenten

tRNA is provided as a lyophilized powder that is soluble in water at a concentration of 2 mg/ml.

Einheitendefinition

One unit will yield an absorbance of 1.0 at 260 nm in 1.0 mL of water (1 cm light path).

Post-translational modification of histone tails is thought to modulate higher-order chromatin structure. Combinations of modifications including acetylation, phosphorylation and methylation have been proposed to provide marks recognized by specific proteins. This is exemplified, in both mammalian cells and fission yeast

Meiosis is a cellular program that generates haploid gametes for sexual reproduction. While chromosome events that contribute to reducing ploidy (homologous chromosome pairing, synapsis, and recombination) are well conserved, their execution varies across species and even between sexes of the

After four decades of research aimed at understanding tRNA selection on the ribosome, the mechanism by which ribosomal ambiguity (ram) mutations promote miscoding remains unclear. Here, we present two X-ray crystal structures of the Thermus thermophilus 70S ribosome containing 16S
