Molecular Weight Cut Off

The molecular weight cut-off values (MWCO) of NF membranes lie in the approximate range 200 to 1000 Daltons, between the ultrafiltration and reverse osmosis separation ranges. Mass transport in NF is based on two mechanisms: sieving and charge effects. Some sugars, such as pectate oligosaccharides (which are acidic in

Inulin clearance (CIn) is the usual gold standard for evaluating glomerular filtration rate (GFR), but technical difficulties and patient inconvenience prevent its widespread use (1). The most commonly used marker for GFR is serum creatinine, but muscle wasting and tubular secretion may lead to overestimation of GFR (2)(3). Serum concentrations of the low-molecular weight proteins cystatin C.
