Cell Line Name

NP cl.120

Cell Line Description

NP cl.120 monoclonal antibody is one of a range of well characterised measles virus antibodies used to measure synthesis and topological accumulation of measles virus antigen during the lytic cycle. This anti-nucleoprotein antibody is negative for haemagglutinin and hemolysin inhibition as well as neutralisation assays and gives immunofluorescence only on fixed tissue.

Culture Conditions

Cell Type

Hybridoma

Subculture Routine

Maintain cultures between 1-5 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%.
