Application
Streptavidin iron oxide particles are used in protein chromatography, affinity chromatography, and recombinant protein expression and analysis. Streptavidin iron oxide particles have been used to study imaging of cellular spread on a three-dimensional scaffold by means of a novel cell-labeling technique for high-resolution computed tomography. Streptavidin iron oxide particles have also been used to study in vitro biomedical applications of functionalized iron oxide nanoparticles.
Used for the purification of biotin containing proteins or DNA binding proteins
Physical form
Suspension in 0.85% NaCl, 0.01 M phosphate, pH 8.0, containing 0.1% bovine serum albumin, 0.1% sodium azide

RNase J1 is the major 5'-to-3' bacterial exoribonuclease. We demonstrate that in its absence, RNA polymerases (RNAPs) are redistributed on DNA, with increased RNAP occupancy on some genes without a parallel increase in transcriptional output. This suggests that some of

Saccharomyces cerevisiae pyruvate kinase 1 (Pyk1) was demonstrated to be associated to an immunoprecipitate of yeast protein kinase A holoenzyme (HA-Tpk1.Bcy1) and to be phosphorylated in a cAMP-dependent process. Both glutathione S-transferase (GST)-Pyk1 and GST-Pyk2 were phosphorylated in vitro by

Queuosine (Q), one of the most complex modifications occurring at the wobble position of tRNAs with GUN anticodons, is implicated in a number of biological activities, including accuracy of decoding, virulence, and cellular differentiation. Despite these important implications, its biosynthetic

Computed tomography (CT) represents a truly three-dimensional (3D) imaging technique that can provide high-resolution images on the cellular level. Thus, one approach to detect single cells is X-ray absorption-based CT, where cells are labeled with a dense, opaque material providing
