MARKERENZYMEDISTRIBUTION 947 mMpiperazine-N,N'-bis(2-ethanesulfonic acid) atpH 6.9 (10). Thewashed cells were fixed in 5%glutaral- dehydediluted in PMbuffer. Afterfixation for 3hat Preparation of cytosols from several estrogen target organs was compared, with use of the Beckman Airfuge and a preparative ultracentrifuge. The specific estrogen-binding capacities of cytosols prepared with these instruments were indistinguishable. Refrigerated floor centrifuges perform high-speed sample separations in adjustable temperature ranges between -20 °C and + 40 °C. These models are used in various DNA, RNA, viral and protein research and clinical applications. ultracentrifuge tubes (Beckman Coulter P/N 331372) which were programmed in as new labware. A slow pipetting technique with liquid level sensing was used to minimize interface mixing of the gradients. The gradient was an overlaid gradient, as shown in Table 1. Differential Centrifugation and Density Gradient Run The rotors are described in individual manuals that accompany each rotor. Information on rotors and accessories is also available in Rotors and Tubes for Tabletop Preparative Ultracentrifuges (TLR-IM) and in the Beckman Coulter Ultracentrifuge Rotors, Tubes &...
