The biotin tag can be used in affinity chromatography together with a column that has avidin (or streptavidin or neutravidin) bound to it, which is the natural ligand for biotin. However, harsh conditions (e.g., 6M GuHCl at pH 1.5) are needed to break the avidin/streptavidin - biotin interaction, which will most likely denature the protein carrying the biotin tag. If isolation of the tagged protein is needed, it is better to tag the protein with iminobiotin. This biotin analogue give… WebThe avidin-biotin bond is the strongest known biological interaction between a ligand and a protein (Kd = 1.3 x 10-15 M at pH 5.0) (1). The affinity is so high that the avidin-biotin …
WebThe avidin-biotin system is a simple yet elegant system to link proteins in immunoassays by exploiting the very high affinity of hen egg-white avidin for biotin (vitamin B7). Streptavidin, isolated from bacteria, binds to biotin equally well but lacks the glycoprotein portion found on avidin and therefore shows less non-specific binding. In ...
