Addgene: Isolating a Monoclonal Cell Population by ...

Aug 01, 2016 Isolate cells from the stable cell pool by trypsinization and break up any cell clumps into individual cells by passing several times through a serological pipet or by passing through a 0.40 m cell strainer mesh. Quantitate the cell concentration in this homogenized cell solution with a hemocytometer or other cell counter.

Aug 07, 2018 Testing forward typing, an individual's red cells (in a 2%-5% saline suspension) are mixed in a test tube with separate reagents anti-A and anti-B at room temperature. After centrifugation, the pelleted cell button is gently resuspended and examined for agglutination. If there is agglutination, this will indicate a positive reaction.

Precipitated protein, genomic DNA, and cell debris are then pelleted by a centrifugation step and the supernatant is loaded onto a column. Contamination like salts, metabolites, and soluble macromolecular cellular components are removed by simple washing with ethanolic wash buffer (1.0 M NaCl, 50mM MOPS, pH 7.0, isopropanol (v/v) 15 %).

Sep 01, 2004 This step removes clumps and prevents clogging of the cytometer. If cell suspensions are used, centrifuge cells 5 min at 4000 g, remove supernatant, and suspend the pellet in 1 ml of binding buffer. Repeat this process two times. After the final wash, add 0.5 to 1 ml of binding buffer to obtain 1 10 6 cells/ml.

Therefore, after thawing the cells, it is necessary to dilute and remove the DMSO before transferring the cells to tissue culture flasks. Media other than DMEM can also be used for growing Vero cells. See COMMENTARY for more information. Pellet cells by centrifugation at 200 g for 5 minutes at room temperature.
