Hello Theresa,

We have been using the TECNOMOUSE instrument from INTEGRA to produce mAbs
in-vitro. Normally we get conc. of 1-5 mg/ml in the harvested supernatant.
Try our this link:

The company has now brought out their new CELLine bottles, and we are
testing  the CL1000 at the moment. Cells are growing well and we are about
to start harvesting supernatant. The bottle should be useful for amounts up
to 100 mg of mAbs. Try this link:

Our experience tells us that the in-vitro produced mAbs are purer and works
better than those produced in ascites. 

The cost issue is of course very dependent on the cost of mice. The use of
the in-vitro method from INTEGRA save a lot of serum, so your main cost is
the price of the cassette or bottle and the media.

If you need a good supplier of mAbs for immunphenotyping on flow cytometry,
you should check out this site:
