Formal Ether Sedimentation Technique - Microbe Online

Centrifuge the suspension at relative centrifugal force (RCF) of 600 g (about 2000 rpm) for no less than 10 minutes. The suspension should yield about 0.75mL of sediment for fresh specimens and 0.5 mL for formalinized feces. Decant the supernatant and wash the …

Dec 02, 2017 After centrifugation, the supernatant was discarded and two types of solid material were obtained: the first, a light brown color mucilage, was discarded, and the second was collected as starch. The starch was dried in a tray dryer with air circulation (Solab-SL102) at a temperature of 45 C to constant mass.

Presence of an extended N301 glycan might provide some hindrance to binding of PGT128 Fab, but we only observe minimal ordered density for glycosylation at N301 in our map, which limits further analysis.

Preanalytical requirements of urinalysis - PMC

Feb 15, 2014 A 5-minute centrifugation time at 400 g [RCF, relative centrifugal force (g) = 1.118 10 −5 radius (cm) RPM (revolutions per minute)] preferably at 4 C is necessary for optimal sediment concentration. The use of the centrifuge brake is contraindicated because of sample resuspension with decreased numbers of urinary formed elements.

Centrifugation - Wikipedia

The conversion factor between RPM and g depends on the radius of the centrifuge rotor. The particles' settling velocity in centrifugation is a function of their size and shape, centrifugal acceleration, the volume fraction of solids present, the density difference between the particle and the liquid, and the viscosity. The most common ...
