Summary of Fibronectin Fragments (FN-fs) Generated by MMP-1, -3, -13, and -14 after 24 Hours of Digestion

MMP-1		MMP-3		MMP-13		MMP-14
pH 5.5	pH 7.5	pH 5.5	pH 7.5	pH 5.5	pH 7.5	pH 5.5	pH 7.5
—a	150 kDa	150 kDa	150 kDa	150 kDa	150 kDa	—a	150 kDa
		120 kDa	120 kDa	120 kDa	120 kDa		120 kDa
		70 kDa	70 kDa	70 kDa	70 kDa

Note: The FN-fs were detected using a mouse monoclonal antibody specific for an epitope located within the fourth-type 3 repeat of plasma FN. The molecular weights of the FN-fs were determined using Totallab TL100 software (Nonlinear Dynamics, Durham, NC) from Figures 2A and 3A.

^aNo fragments were detected.
