Cell Line Name

NIH-3T3 4-2

Cell Line Description

A mouse fibroblast cell line which has an integrated mutant Moloney MuLV. The cell line can be used to generate helper-free defective retroviruses. Cells have now lost their contact inhibition. Contact inhibition is the natural process of arresting cell growth when cells come into contact with each other. It is not possible to be sure how the loss of contact inhibition may affect other characteristics of the cell line. This cell line catalogue number continues to be a popular choice. The key consideration is whether the characteristic of contact inhibition is required for the work the cell line is to be used for. For example, it is required when testing the affects of expression of potential oncogenes where the induction of the loss of contact inhibition is being measured, whereas it is of less significance when using the cell line to express recombinant proteins for production and purification.

The Culture Collections represent deposits of cultures from world-wide sources. While every effort is made to ensure details distributed by Culture Collections are accurate, Culture Collections cannot be held responsible for any inaccuracies in the data supplied. References where quoted are mainly attributed to the establishment of the cell culture and not for any specific property of the cell line, therefore further references should be obtained regarding cell culture characteristics. Passage numbers where given act only as a guide and Culture Collections does not guarantee the passage number stated will be the passage number received by the customer.

Cultures supplied by Culture Collections are for research purposes only. Enquiries regarding the commercial use of a cell line are referred to the depositor of the cell line. Some cell lines have additional special release conditions such as the requirement for a material transfer agreement to be completed by the potential recipient prior to the supply of the cell line.
