Membrane plasmapheresis was introduced in 1978 as a new method for performing therapeutic plasma exchange. Its principal advantages over traditional techniques include speed, ease of performance, and ready adaptability to clinical centers already performing routine extracorporeal therapy. The appearance of a membrane plasmapheresis circuit (vascular access,(More)

SETTING Patients were recruited by newspaper advertisements and general practitioners who were also responsible for enrolment. Pre-treatment assessments took place in seven general(More)
In vitro and in vivo sieving coefficients (SC) have been determined for a spectrum of proteins ranging in molecular weight from 66,500 daltons (albumin) to 2.4 million (beta-lipoprotein) daltons for three commercially available membrane plasma separation devices: the Plasmaflo 0.1, Plasmaflo 02, and Plasmaflux. A model relating serum level of a protein to(More)
The refolding of iodoacetic acid-blocked human serum albumin (HSA) was studied using a modified competitive inhibition ELISA. A maximum of 89% native activity was detected 24 hours after initiating refolding using an albumin concentration of 600 micrograms/mL. The presence of both monomer and polymer HSA was studied using native polyacrylamide gel(More)
An immunoadsorption system of monoclonal antibody immobilized on a polyolefin alloy fiber is described for extraction of serum gastrointestinal cancer antigen (GICA). Continuous circulation or single passage of plasma from gastrointestinal cancer patients through this antibody-fiber matrix resulted in 90% depletion of circulating GICA in 2 h using 0.6 mg(More)
