NS-1 CELL LINE IN THE UK

[DALE hreczuk-hirst]

Hello,
         Can anyone tell me of a source of NS-1 myeloma cells available in the UK
We have some here but thier now at passage 19 - 21 so thier long in the tooth even 
for imortal cells.  Fusion using these old cells works bu cloning efficiency is way 
down to 15-20 % so we are losing all the cells a  the limit dilution cloning step.

Thanks in Advance
Dale
