DNA Detection Using Recombination Proteins
DNA amplification is essential to most nucleic acid testing strategies, but established techniques require sophisticated equipment or complex experimental procedures, and their uptake outside specialised laboratories has been limited. Our novel approach, recombinase polymerase amplification (RPA), couples isothermal recombinase-driven primer targeting of template material with strand-displaceme...
متن کاملFragmented proteins as food emulsion stabilizers: A theoretical study.
Using a model based on the primary structure of αs1 -casein, the colloid stabilizing ability of fragmented protein and that of the intact chains are compared. We perform self consistent field (SCF) calculations to obtain the induced interaction potentials between the oil droplets, resulting from the overlap of adsorbed protein layers in each case. For the intact αs1 -casein, we confirm the know...
متن کاملTherefore, what are recombination proteins there for?
The order of discovery can have a profound effect upon the way in which we think about the function of a gene. In E. coli, recA is nearly essential for cell survival in the presence of DNA damage. However, recA was originally identified, as a gene required to obtain recombinant DNA molecules in conjugating bacteria. As a result, it has been frequently assumed that recA promotes the survival of ...
متن کاملUtilization of Site-Specific Recombination in Biopharmaceutical Production
Mammalian expression systems, due to their capacity in post-translational modification, are preferred systems for biopharmaceutical protein production. Several recombinant protein systems have been introduced to the market, most of which are under clinical development. In spite of significant improvements such as cell line engineering, introducing novel expression methods, gene silencing and pr...
متن کاملImprovement of recombination efficiency by mutation of red proteins.
The Red recombination system of the bacteriophage lambda is a useful tool for engineering bacterial artificial chromosomes (BACs) because desired mutations can be made in any part of the DNA, even in large DNAs, independent of the presence of appropriate restriction enzyme sites. Many have tried changing the inducible promoter or decreasing the copy number of Red genes in Escherichia coli to im...
