bag8ger I cannot profess to having more than a passing acquaintance with project 6, which seems to be related to assays tangentially connected to project 3. The project 6 initiatives though seem to have run into some difficulties:
"...however the results obtained were not as reliable as the visual score in cytokinesis-blocked lymphocytes. For this reason the patent was allowed to lapse."
"Novel chromophores were produced and provisional patents filed. The chromophores that were produced had some useful spectral characteristics and are useful for research purposes, however they were unable to compete with novel products that are now available in the market. Therefore the project has now been discontinued."
