Our current research demonstrates for the first time that IFN-CSP gene can be expressed at high levels in E. coli through codon and expression conditions optimization.
Bacterial expression is limited by the types of eukaryotic proteins that can be expressed at high levels while maintaining solubility, proper folding, and the correct post-translational modifications.
In RA, proinflammatory ligands of the RAGE, including S100A12 and HMGB1, are reported to be expressed at high levels, levels of soluble RAGE are reduced and RAGE expression is increased by synovial macrophages [ 17, 38, 39].
PRG-3 appeared to be expressed at high levels in all samples except primary prostate cancer where the expression level appeared low.
Persistent genes, although not ubiquitous, are conserved in a majority of genomes, tend to be expressed at high levels, and are frequently located on the leading DNA strand.
But Khavari and Sen suspected that it had a role in adult stem cells — in part because it's been shown to be expressed at high levels in certain human cancers.
For example, a biomarker might be expressed at high levels within the primary tumor which in most cases is the only site where a biopsy is taken but at much lower or absent levels in one or more metastatic lesions.
By further rounds of random mutagenesis and ribosome display selection, binders with picomolar affinity were obtained that were entirely monomeric and could be expressed at high yields in the cytoplasm of Escherichia coli.
Our current research demonstrates for the first time that by using the TBIO method a synthetic ORF encoding hIFNα2b gene can be expressed at high levels in E. coli.
While it naturally resides in the periplasm, MBP can also be expressed at high yields in the cytoplasm.
Ncl has previously been reported to be expressed at high levels in both murine [15] and human ES cells [16] where high levels of Tpt1 also were reported.
