Welcome to BioDak!


BioDak, LLC is headquartered in Kimball, South Dakota and is using the latest advances in technology to produce cattle that are free of prions and antibodies.

Cell culture production can be slow, expensive and complicated and there are risks associated with using animal derived products coming from unknown quality and sources. BioDak products provide unique capabilities that address both of these issues.

Bovine sera and reagents that are free of prions mitigate risk associated with BSE (bovine spongiform encephalopathy, commonly known as "mad cow disease") transmission and sera that is free of antibodies optimizes cell culture development.
