| Comments | WEHI-231 cells do not secrete IgM into medium unless stimulated with lipopolysaccharide (0.01 to 3 μg/mL). Tested and found negative for ectromelia virus (mousepox). |
| Complete Growth Medium | The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: 2-mercaptoethanol to a final concentration of 0.05 mM; fetal bovine serum to a final concentration of 10%.

| Subculturing | Optimum culture recovery from a frozen vial is in a T25 flask at a density between 2 to 5 X 105 viable cells/mL. If recovered at 5 X 105 viable cells/mL, media will need to be added to the culture within the first 3 days, before the density reaches 1 X 106 viable cells/mL, at which point the viability drops drastically.
After cells recover, expansions can be done at 1 X 105 viable cells/mL by adding media to decrease the cell concentration. This cell line forms tight clusters of viable cells accompanied by some single non-viable cells plus debris in suspension. With increased growth the clusters become larger. As the cell density nears 1 X 106 cells/mL, the single (non-clustered) and non-viable cells increase along with the amount of debris. At subculture, break up clusters by gentle pipetting. Established cultures can be grown in T75 flasks. Subcultivation Ratio: Add fresh medium every 2 to 3 days (depending on cell density)
