Biotin streptavidin western blot protocol
Webnumerous variations in western blotting detection that include, but are not limited to, the previously mentioned strategies. In far-western blotting, labeled binding partners may be labeled by an in vitro translation reaction with 35S-labeled probe. Biotinylating the probe and detecting with a biotin-binding protein conjugate is also possible.

WebFar–Western Blot Analysis. Far–western blot analysis is an alternative method to analyze protein–protein interactions that entails probing proteins that have been separated by gel electrophoresis with tagged bait proteins, and then detecting the interacting proteins (prey) through multiple methods. In recent years, far–western blot ...
Webcomplex lysates, nonspecific detection of endogenous biotin carrier proteins can also be problematic (Schmidt and Skerra 1993). However, StrepTactin conjugates are less cross-reactive with the 22 kD E. coli biotin carrier protein compared to streptavidin conjugates. Thus, preblocking the blot with avidin is not always necessary with StrepTactin WebAvidin, Streptavidin or NeutrAvidin proteins can bind up to four biotin molecules, which are normally conjugated to an enzyme, antibody or target protein to form an Avidin-biotin …
