Cell Line Name

P-tyr-1

Cell Line Description

The hybridoma cell line P-tyr-1 was produced by fusing P3X63Ag8.653 mouse myeloma cells with spleen cells from a female BALB/c mouse immunised with aminobenzyl phosphonate. Aminobenzyl phosphonate is a structural analogue of the side-chain in phosphotyrosine, and was coupled to hemocyanin (antibody P-HC) for immunisation. The secreted IgG1 antibodies react with phosphotyrosine and will detect phosphotyrosine-containing proteins by immunoprecipitation and Western blot analysis. The antibody does not react with phosphoserine or phosphothreonine. The Bovine Viral Diarrhoea Virus (BVDV) status of this cell line was previously described as negative. Results of recent multiple molecular tests for BVDV that were undertaken by two independent testing laboratories were equivocal. This means that we cannot confirm the BVDV status of this cell line.

Subculture Routine

Maintain cultures between 3-9 x 100,000 cells/ml; 5% CO₂; 37°C. When recovering hybridoma cultures from frozen it is not unusual for growth to be slower than expected initially and there may be an observed decrease in viability. Establishment of an actively proliferating culture may take up to 2 weeks. On resuscitation 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 prewarmed growth media+. Remove a sample for counting. Centrifuge at 100 x g for 2-3 minutes to pellet cells and seed at a relatively high density of 5-7 x 10µ cells/ml. Place culture flask flat and observe regularly until viable proliferating cells are seen. Often hybridoma cultures may benefit from being resuspended with media supplemented with 20% FBS in the early critical stage of culture establishment immediately post resuscitation. Once the culture is established in culture the FBS can be reduced to 10%.

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.
