avidin

nanomag®-D particles with diameters of 130 nm, 250 nm and 500 nm are provided with covalently bound avidin on the surface. Avidin binds biotinylated molecules easily and with a high affinity. The protein coated particles can be separated with permanent magnets and are supplied in PBS buffer (pH=7.4) with 0.02 % sodium azide.
