文献和实验The overexpression of toxic recombinant proteins is often problematic, leading to either low production levels or inclusion bodies. Streptavidin is no exception and thus the highest production level reported to date for streptavidin is 70 mg
The Use of Recombinant Fusion Proteases in the Affinity Purification of Recombinant Proteins
of interest, but some affinity tails are able to be linked to either the N- or C-terminus of the protein of interest. The choice of affinity tail to use for the expression of any particular protein is empirical since the factors leading to the high expression of recombinant
Nonradioactive Labeling and lmmunodetection of Recombinant Proteins
Recombinant proteins can be detected and characterized via several immunodetection schemes. Native proteins are typically detected by applying them to a membrane manually or using a vacuum manifold in a dot-or slot-blot format. This approach
