TABLE 1.

Molecular mass determinations of the full-length NC1 domain and the endostatin domain of both murine type XV and XVIII collagens by sedimentation equilibrium. Samples were run in PBS at 4°C.

Protein	<U> (cm³ g⁻¹)	RPM	Calculated mass (kDa)	AUC mass (kDa)	Oligomeric state	Concentration (mg/ml)
XV-ES	0.7326	20,000	20.0	17.4±0.1/16.6±0.1	0.87/0.83	0.5/1.0
XVIII-ES	0.7253	20,000	20.7	18.5±0.1	0.89	0.5
XV-NC1	0.7378	12,000	28.9	90.1±0.7/104.1±1.	3.11/3.6	0.27/0.55
XVIII-NC1	0.7299	12,000	38.0	97.6±0.3	2.56	0.5
