The macromolecular properties of blood-group substances. Sedimentation-velocity and viscosity measurements [PDF]

open access: bronzeBiochemical Journal, 1967
1. Sedimentation-velocity, intrinsic-viscosity and partial-specific-volume measurements on a typical blood-group-specific glycoprotein are reported for a range of environmental conditions. 2. The sedimentation coefficients, S, are strongly concentration-dependent, and follow the reciprocal law; the limiting values at 2°, 25° and 45°, after correction ...
