streptavidin

micromer® particles are available with covalently bound streptavidin on the surface in the size range of 100 nm to 100 µm. Streptavidin coated particles bind biotinylated molecules easily and with a high affinity.
The protein coated particles are supplied in PBS buffer (pH=7.4) with 0.02 % sodium azide.
