Cell Line Name

LY9

Cell Line Description

LY9 was produced from a (C57BL/6 x BALB/c)F1 mouse immunised with a single i.p. injection of the lymphoblastoid B-cell line Leakar and B. pertussis adjuvant. The genotype of the B-cell donor for this line was HLA-A2,B13, Cw- DR7, DQ 2/A24,B13, Cw-,DR7 B35, Cw4, DR3, DQ2. Mice spleen was removed 3 days later and fused with the myeloma P3x63Ag8.653. LY9 monoclonal antibodies were shown to react with cells expressing DRw53, DR7 (in the absence of DRw53) and DRw10. LY9 is also known as LK261.

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%.

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.
