Coated microparticles are prepared either by passive adsorption or covalent coupling depending upon the intended applications.
The avidin coated particles are prepared by covalent coupling.
Some typical data for Avidin polystyrene particles (0.8µ) are : Covalently coated with egg white avidin, avidin content 14 µg/mg of solid particles, 0.212 nmole/mg of solid particles
