WebPurification. 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 ... WebLike biotin, desthiobiotin binds to streptavidin, but its binding affinity is considerably less (2x10E-9 M) than that of biotin (4.0x10E-14 M) (1). Consequently, oligonucleotides labeled with desthiobiotin can be easily displaced from streptavidin by biotin, thereby making recovery of the labeled oligo (for example, in affinity purification ...
WebAffinity tags vary greatly based on size, strength-of-binding and effect on protein solubility and stability. Promega protein purification kits are available for affinity purification using His, GST, HaloTag and Streptavidin/Biotin binding. The most commonly used tag to purify recombinant proteins is the polyhistidine tag.
