Cell Line Origin
Monkey African green kidney, SV40 transformed
Cell Line Description
Derived from CV-1 simian cells transformed by origin-defective mutant of SV40 which codes for wildtype T Ag. Possible host for propagation of pure populations of recombinant SV40 virus. The cells should be handled under laboratory containment level 2.
Application
COS-1 cell line has been used to test the toxicity of various concentrations of iron oxide nanoparticles (for use in medical diagnostics).[1] It has also been used to study the interaction of nanoparticles with their cellular targets.[2]
Virus replication studies: SV40
Culture Medium
Subculture Routine
Split semi-confluent cultures 1:3 to 1:6, i.e., seeding at 2-4x10,000 cells/cm2 using 0.25% trypsin or trypsin/EDTA; 5% CO2; 37 °C. In order to prevent syncitia formation, do not allow cells become confluent.

Why is Vapor Phase Liquid Nitrogen preferred for storage of Cell Line cells?
1 answer-
If ampules are immersed into liquid phase of liquid nitrogen, it increases the risk of the liquid seeping into the vial. This could lead to problems of cross-contamination and increased risk of the ampule exploding when thawed.

-
How many Cell Line cells are in the vial?
1 answer-
Each vial of cells contains 2-3 x 106 cells in 1 ml of freezing media. This is in a 1.8 mL ampule. For exceptionally large cells, counts may decrease. Suspension cells, generally smaller cells, may contain as many as 4-5 x 106 cells/vial to assure optimal viability upon thaw.

How do I handle Cell Line frozen cells upon arrival?
1 answer-
Upon receipt, frozen ampules should be transferred directly to vapor phase liquid nitrogen without delay (-135°C) or liquid phase liquid nitrogen if vapor phase is not available. DO NOT use a -80°C freezer as an alternative; this will result in loss of viability.
