... is determined by the size of albumin (molecular weight 66,000) [ 17 ]. When uremic solutes are selectively removed from the blood through the dialysis membrane with various pore size distribution, concentration polarization and a protein gel layer can develop on the membrane surface (fig. 1 ). Although...

... osmotic pressure in plasma. Such behavior suggests that transport in AV filtration is membrane limited; this is in contrast to earlier models which were based upon boundary layer concentration polarization or unfavorable osmotic gradients.
