Purification and characterization of bovine milk fibronectin

Abstract
SUMMARY: Fibronectins were isolated from both bovine colostrum and fresh milk, and they were found to be very similar to plasma fibronectin. The concentration of fibronectin in milk decreased post partum: 30 µg/ml after 0 d and 2 µg/ml after 7–851 d. No fibronectin could be detected in any brands of ultra heat treated liquid milk on the market (≤0·006 µg/ml).
