emptied and washed, and the 24h efflux of inulin was determined; it is plotted against the final swelling ratio from the experiment in which the sac was stretched. An unstretched control is also included. In a similar unstretched sac, the half-time of raffinose escape was I4Omin. Clearly inulin escapes faster than the polyethylene glycol of comparable molecular weight at all porosities, but at ...
The compliance of 581 drug addicts attending six methadone substitution outpatient clinics was determined over a period of 18 months. Urine from these patients was labeled following oral administration of low molecular weight polyethylene glycols as marker substances. These substances were measured in approx. 5800 urine samples. A protocol for applying marker substances and ways to prevent subs...
The effect of osmotic protectors (sucrose and polyethylene glycols) and of a decrease in the detergent concentration at different points of hemolysis of human erythrocytes by sodium dodecyl sulphate on the shape of kinetic curves of hemolysis were studied. It is shown that slow detergent-induced hemolysis follows the colloid-osmotic mechanisms. Evidence is provided that rapid hemolysis by sodiu...
A method for capture and release of cells was developed using a photolabile linker and antibody-attached glass surface with a poly(ethylene glycol) (PEG)-pattern.
