Hybridoma cell growth and monoclonal antibody production in dialyzed continuous suspension culture were investigated using a 1.5-L Celligen bioreactor. Medium supplemented with 1.5% fetal bovine serum was fed directly into the reactor at a dilution rate of 0.45 d(-1). Dailysis tubing with a molecular weight cut-off (MWCO) of 1000 was coiled inside the bioreactor. Fresh medium containing no serum or serum substitutes passed through the dialysis tubing at flow rates of 2 to 5 L/d. The objective was to remove low molecular weight inhibitors, such as lactic acid and ammonia, by diffusion through the tubing, while continuously replenishing essential nutrients by the same mechanism...

Using matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOFMS) we studied the decomposition pathway of a prooligonucleotide during incubation in a crude cell extract. This study, involving no sample processing, except drop dailysis to remove salts, led us to identify more than thirty metabolites from several metabolic pathways.

Quantitative Determination of the Main Metabolites of Acetylsalicylic Acid / 2nd Communication: The concentrations of salicylic acid and its metabolies in patients with renal insufficiency 9 patients suffering from renal insufficiencies of varing degrees and treated regularly by hemodialysis were given 1.5 g Colfarit (microcapsulated acetyl salicylic acid) as a single dose. The concentrations of salicylic acid (SA), salicyluric acid (SU), further salicylic acid conjugates (SAC) and salicyluric acid conjugates (SUC) were determined in the blood plasma...

During 1971-5, 72 episodes of acute renal failure were treated in 70 children aged up to 16 years. The commonest causes were renal hypoperfusion (31 cases), haemolytic-uraemic syndrome (12), glomerulonephritis (9), septicaemia (5), and congenital abnormalities (6). Though referral from other hospitals was generally prompt, 10 out of 51 patients had been observed for up to seven days before transfer. Dailysis was used in 44 cases, the most common complications of which were peritonitis in those treated with peritoneal dialysis and acute changes in fluid balance in those treated with haemodialysis...

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase
