Terms and Licenses
Traptavidin has a lower off-rate and lower on-rate for biotin conjugates, as well as higher mechanical strength and higher thermal stability. It is tetramer, refolded from inclusion bodies.
This particular material is subject to a UK priority patent application (0919102.4) filed on 30th October 2009
