Osmotic Pressure, Molecular Weight, and Stability of Serum Albumin”
Because of the discrepancies at the time this investigation was begun in the estimates of t’he molecular weight of serum albumin, as made by Siirensen (1) (45,000) and hdair (2) (62,000) by means of osmotic pressure experiments, and by Svedberg and Sjiigren (4) (67,500) from ultracentrifugal measurements, the osmotic pressure of this protein was reinvest’igated under more suitable experimental ...
متن کاملOsmotic pressure contribution of albumin to colloidal interactions.
Two surfaces that come in close contact in a solution with macromolecules present experience an attractive force caused by the osmotic pressure. We present a measurement of this effect by using a micrometer-sized sphere bound to a flat plate through a single molecular attachment in an albumin-containing solution. We obtain the osmotic part of the interaction potential with a resolution of <1 nm...

متن کاملInteraction of Phthalocyanine with Egg albumin and Bovine serum albumin
The interaction of bovine serum albumin ( BSA) and egg albumin with water solublephthalocyanine, cobalt (ΙΙ) 4, 4′ , 4′′, 4′′′- tetrasulfophthalocyanine ( CoTSPc) , has been studiedby the UV- Vis method at pH 7.0 and five different temperatures 20, 25, 30, 35 and 40°C. Theformation constants have been elucidated by using spectrophotometric titration and computerSQUAD program data refinement. Th...
متن کاملSalt Effect on Osmotic Pressure of Polyelectrolyte Solutions: Simulation Study
We present results of the hybrid Monte Carlo/molecular dynamics simulations of the osmotic pressure of salt solutions of polyelectrolytes. In our simulations, we used a coarse-grained representation of polyelectrolyte chains, counterions and salt ions. During simulation runs, we alternate Monte Carlo and molecular dynamics simulation steps. Monte Carlo steps were used to perform small ion excha...
