Cell Line Name

B1D6

Cell Line Description

The hybridoma B1D6 was obtained by immunising BALB/c mice with human placental extract followed by intravenous injections with purified Fc gamma-receptor (receptor for the Fc portion of immunoglobulins, FcR). Spleen cells were then fused with the myeloma P3X63Ag8 to establish B1D6 secreting IgG1, kappa, monoclonal antibodies. This antibody has been shown to stain FcR-positive areas in sections of placental tissues, inhibited the haemadsorption of placental tissue of erythrocytes sensitised with IgG antibodies and the agglutination of these erythrocytes by FcR.

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.
