Abstract
Aqueous suspensions of mixtures of the rodlike virus tobacco mosaic virus (TMV) with globular macromolecules such as polyethylene oxide (PEO) or bovine serum albumin (BSA) phase separate and exhibit rich and strikingly similar phase behavior. Isotropic, nematic, lamellar, and crystalline phases are observed as a function of the concentration of the constituents and ionic strength. The observed phase behavior is considered to arise from attractions between the two particles induced by the presence of BSA or PEO. For the TMV/BSA mixtures, the BSA adsorbs to the TMV and bridging of the BSA between TMV produces the attractions. For TMV/PEO mixtures, attractions are entropically driven via excluded volume effects known alternatively as the "depletion interaction" or "macromolecular crowding."
摘要
杆状病毒烟草花叶病毒（TMV）与球状大分子如聚环氧乙烷（PEO）或牛血清白蛋白（BSA）的混合物的水悬浮液会发生相分离，并表现出丰富且极为相似的相行为。随着成分浓度和离子强度的变化，会观察到各向同性相、向列相、层状相和结晶相。观察到的相行为被认为是由BSA或PEO的存在所诱导的两种颗粒之间的吸引力引起的。对于TMV/BSA混合物，BSA吸附到TMV上，并且TMV之间的BSA桥接产生吸引力。对于TMV/PEO混合物，吸引力是通过已知的排斥体积效应（也称为“耗尽相互作用”或“大分子拥挤”）由熵驱动的。
