Cell Line Description

Transformed with sheared human Ad5 DNA. Sensitive to human adenoviruses and adenovirus DNA. Can be used to isolate transformation defective host-range mutants of Ad5 and for titrating human adenoviruses. This is a hypotriploid human cell line. The modal chromosome number was 64, occurring in 30% of cells. The rate of cells with higher ploidies was 4.2%. The der (1)t(1;15) (q42;q13), der(19)t(3;19)(q12;q13),der(12)t(8;12) (q22;p13) and four other marker chromosomes were common to most cells. Five other markers occurred in some cells only. The marker der(1) and M8 (or Xq+) were often paired. There were four copies of N17 and N22. Noticeably in addition to three copies of X chromosomes, there were paired Xq+ and a single Xp+ in most cells. The Ad insert was shown to consist of a colinear segment from nucleotides 1 to 4344 integrated into chromosome 19 (19q13.2). Expression of an unusual cell surface receptor for vitronectin has been reported. This is composed of the integrin beta-1 subunit and the vitronectin receptor alpha-v subunit. PLEASE NOTE: 293 cells detach at room temperature; may take up to seven days to reattach.

Subculture Routine

Split sub-confluent cultures (70-80%) 1:2 to 1:6 i.e. seeding at 2-5x10,000 cells/cm² using 0.05% trypsin or trypsin/EDTA; 5% CO₂; 37°C. When resuscitating a frozen ampoule of cells we recommend the cells are seeded at the higher seeding level i.e. 5 x10,000/cm². Cells may take up to 7 days to attach after resuscitation and subculture. Cells detach easily at room temperature or during transit, therefore growing cultures may be received with cells in suspension. In this event, centrifuge contents of flask and reseed to allow re-attachment of cells. These cells should be frozen in 5% DMSO : 95% FCS

Unless specified otherwise, at ECACC we routinely handle all of our cell lines at containment level 2 in accordance with the ACDP guidelines (Advisory Committee on Dangerous Pathogens) (UK). All cell cultures have the potential to carry as yet unidentified adventitious agents. It is the responsibility of the end user to ensure that their facilities comply with biosafety regulations for their own country.

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.
