Pressure dependence of the apparent specific volume of bovine serum albumin: Insight into the difference between isothermal and adiabatic compressibilities.

There are some theoretical arguments related to interpreting the adiabatic compressibility (beta(s)) of a protein determined from the sound velocity and the difference between beta(s) and isothermal compressibility (beta(T)). To address these problems experimentally, we constructed a high-pressure oscillating densitometer and used it to measure the apparent… (More)
