Cell Line Name


Cell Line Description

BEAS-2B cells were derived from normal bronchial epithelium obtained from autopsy of non-cancerous individuals. Cells were infected with a replication-defective SV40/adenovirus 12 hybrid and cloned. Squamous differentiation can be observed in response to serum. This ability can be used for screening chemical and biological agents inducing or affecting differentiation and/or carcinogenesis. The cell line has been applied for studies of pneumococcal infection mechanisms. BEAS-2B was described to express keratins and SV40 T antigen. Subculturing the cells before confluency is necessary as confluent cultures rapidly undergo squamous terminal differentiation. This material is cited in a U.S and / or other Patent (U.S. Pat. 4,885,238) and may not be used to infringe the patent claims.

Subculture Routine

A centrifugation step to remove the cryoprotectant is essential. Rapidly thaw the frozen ampoule in a water bath at 37°C for 1-2 minutes. Transfer the contents to a centrifuge tube and slowly add 5-10ml of pre-warmed growth media. Remove a sample for counting. Centrifuge at 100-150g for 2-3 minutes to pellet cells and seed at 1x10⁴ cells/cm². Check cultures daily and passage sub-confluent cultures (maximum 70% confluence) using 0.05% trypsin or trypsin/EDTA. Incubate at room temperature for 5-10 min until cells detach. Add fresh medium and disperse cells, centrifuge and resuspend pellet in medium. Seed into new flasks between 0.3-1x10⁴ cells per cm². Flasks have to be precoated with a mixture of 0.01 mg/ml fibronectin, 0.03 mg/ml collagen and 0.01 mg/ml bovine serum albumin dissolved in BEGM. Add mixture at ratio of 0.2 ml/cm² surface area. Incubate at 37°C overnight (it is preferable to use vessels with tightened, plug-seal caps to prevent evaporation during the coating process). Coated flasks can be stored with solution at room temperature, light protected, for up to 1 month. Prior to use, remove coating solution from the flask and wash at least once with PBS before addition of cells.
Note: BEGM medium is almost serum-free, therefore trypsin inhibitor is essential. Add an equal or greater volume of trypsin inhibitor as trypsin used, centrifuge and reseed cells in collagen coated flasks using culture medium.
When freezing cells down use 50:50 fresh culture medium:conditioned medium plus 10% DMSO

Culture Medium

BEGM, also known as LHC-9 with modification (available from Clonetics Corporation, CC3171 (BEBM) plus additives CC4175 or BEGM Bullet Kit, CC3170); Note: Additives supplied contain gentamycin which has been omitted for culture at ECACC; media is serum-free.

If use of this culture results in a scientific publication, it should be cited in the publication as: BEAS-2B (ECACC 95102433).

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.
