The procedure is simple to perform and is capable of good recoveries, but is slow and cumbersome and always results in dilution of the sample. If an antibody is to be purified by gel filtration and ion exchange chromatography, it is strongly advisable to perform the gel filtration first ...
The gaseous cleaning step is enhanced by varying the pressure within the housing (11) of the filter (10) while the gas is being introduced into the filter.KOPP, CLINTON VIRGILSTREETON, ROBERT JOHN WILLIAMFABIG, MARCUS JOHNWYATT, KERRIE
Step 1:Blood is introduced into the platform though the sample inlet. The ports are sealed, and the disc is placed on a motor to impart centrifugal force onto the sample at a given revolutions per minute (RPM). The centrifugal force causes the blood to flow away from the center of rotati...
The procedure consists of filtering the reaction mixture multiple times through membrane micropores with the help of two syringes, which make the cross filtration process less laborious. The method saves time, allows conjugation of less than 1mg protein and produces conjugates better than those ...
To perform buffer exchange manually, we recommend following this procedure: Prepare Exchange Buffer that is 5X the volume of your sample. Set up your Pierce Crossflow Filtration Cassette as stated in the user manual. Turn on the pump and concentrate your sample until the volume is reduced ~90...

Detergent is then preferably removed from the mixture using, for example, polystyrene bead adsorption followed by subsequent removal, or dialysis using, for example, a cellulose acetate dialysis membrane having a molecular cut-off of 1000 Da or 2000 Da. This procedure results in multilamellar and ...
Procedure for dewatering sewage sludge comprising the steps of subjecting pumpable sludge to chemical pretreatment with addition of a flocculation agent, pre-dewatering the chemically pretreated sludge by gravity filtration and conveying the pre-dewatered sludge by gravity, dewatering the pre-dewatered ...
