The two most common problems during recombinant protein expression are low expression level and solubility of the target protein. (neb.com)

Herewe report the structure of a single-domain bacterial fasciclin I protein, Fdp, in the free-living photosynthetic bacterium Rhodobacter sphaeroides, and show that it confers cell adhesion properties in vivo. (whiterose.ac.uk)
NEB also offers solutions for expressing these types of proteins, either in vitro or in vivo. (neb.com)
Two compounds, Compound 1 (1,4-dihydrophenanthrolin-4-one-3-carboxylic acid) and Compound 5 [8-(N-butyl-N-ethylcarbamoyl)-1,4-dihydrophenathrolin-4-one-3-carboxylic acid], with comparable potencies in vivo, were chosen to investigate the effect of the inhibition of the hydroxylation of newly synthesized uterine collagen on the turnover of this protein in vivo.

Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. (bvsalud.org)

Eukaryotic DNA repair helicase RAD3/ERCC-2, an ATP-dependent 5'-3' DNA helicase involved in nucleotide excision repair of UV-damaged DNA. (embl.de)

After expression, the protein is captured by means of immobilized metal affinity chromatography (IMAC). (genengnews.com)
This makes them suitable for the purification of proteins from eukaryotic samples, thereby extending the use of polyhistidine proteins from bacterial to more complex expression systems. (genengnews.com)
The expression of IdeS was followed by constructing a fused protein with GFP and measuring the fluorescence with flow cytometry. (lu.se)
Thanks for holding, and welcome to the New England BioLabs Solutions for the Expression of Difficult Proteins conference call. (neb.com)
Welcome to everyone who has chosen to join us for this information session on solutions for the expression of difficult proteins. (neb.com)
First let me address the problem of low target protein expression. (neb.com)
Finally, low expression may be due to uncontrolled expression of toxic protein during the culture outgrowth phase. (neb.com)

Cube Biotech offers PureCube resins for the purification of His-tagged proteins. (genengnews.com)
