  Singer JA, et al. Interaction of a mouse macrophage cell line with homologous erythrocytes. J. Reticuloendothel. Soc. 31: 489-499, 1982. PubMed: 7120230xa0xa0transfection hostxa0 |
| Derivation： | The IC-21 cell line was derived by transformation of normal C57BL/6 mouse peritoneal macrophages with SV40. |
| Receptor Expression： | Receptor expression:xa0Fcxa0Ref |
| Genes Expressed： | lysozyme |
| Cellular Products： | lysozyme |
| Comments： | This line shares many properties with normal mouse macrophages and display macrophage specific antigens.
They have phagocytic and cytolytic properties, can lyse tumor targets in vitro and appear to be more differentiated than cells of the P388D1 macrophage line.
Trypsin is toxic to this line.
The cells produce large quantities of acid and the medium should be changed frequently.
Tested and found negative for ectromelia virus (mousepox). |
| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, ATCC 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (ATCC 30-2020) to a final concentration of 10%.
|
| Subculturing： | Rinse the monolayer twice with 10 to 15 mL of Ca++/Mg++-free PBS (ATCC® No. 30-2200), xa0then add an additional 10 to 15 mL of the same solution to the cells. Let the culture stand for 5 to 10 minutes at room temperature, then gently bang or tap the flask, or use a sterile cell scraper to dislodge any adherent cells. Pipette the detached cells up and down using a 5 or 10 ml sterile pipette to break up the clumps but avoid the creation of foam. Centrifuge the cells at 125 x g for 5 to 7 minutes and aspirate the supernatant. Gently resuspend the cells in complete growth medium and perform a cell count to calculate the total viable cell number. Subculture the cells into new vessels using a split ratio of 1:2 to 1:4.
Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:4 is recommended
