Ultracentrifugation in polyethylene tubing: an efficient method to concentrate protein solutions on the microliter
Journal of Biochemical and Biophysical Methods
|October 1, 1981
Abstract:
An ultracentrifugation procedure is described to concentrate protein solutions on the microliter scale. Protein solutions were centrifuged in U-shaped lengths of polyethylene tubing at 160000 X g for 15 h and thereafter fractionated by cutting the tubing. The method can be performed in a conventional ultracentrifuge and needs no special equipment.
