In Topic: Problems with MycoAlert (Lonza)

11 January 2013 - 03:40 AM

Clare_williams1983, did you ever manage to get an answer out of Lonza about the accuracy and precision of mycoalert?

For my 2 cents I think it's very important that you use a sensitive luminometer setup and this is probably why Lonza have produced a large table of recommended machines for the assay (http://bio.lonza.com...uminometers.pdf).

Using a BMG Pherastar with a luminometer optic module, I regularly find my negative and positve controls work as expected in the assay. My only concern is that there is a high false positive rate and that's going to take me some time to determine this value.

The samples that were identified as mycoplasma positive in this assay turned out to be negative by PCR and Hoechst dye test.
