Hi Ryan As I remember the idea was to collect function of the flow cytometry instruments to help in hierarchy placement. If you have already done this and submitted these to the Function branch then this is excellent. However I had a look at the function branch and at the minute it there seems to no functions. Worryingly it has an Instrument_function class. I know this branch is one of the more recent ones, although, a question for the branch. is it going to be common practice to create a hierarchy based on the object that inheres the function rather that what the function is?

Hi, I think the functions should not be sorted according to the instruments that perform them. This should be 'inferable' via a has_function relation. However the inheritance of this has_function relation and its values needs to be discussed. Of cause we will run into problems as long as we have is_a and part_of mixed Hierarchies, e.g. currently we have sample_fluid is_a fluidic_subsystem is_a instrument, which is wrong... and would clearly prevent any function inheritance.

=20 What sort of granularity for instrument function hierarchy do you envisage? =20 For example, at the highest level flow cytometers can be used to analyze particles suspended in a fluid (and the subtype of flow cytometer sorters can put them into tubes based on their characteristics). Particles are usually cells, but can be microorganisms. At a more granular level the function of a flow cytometer can be to examine many cellular parameters on live or fixed cells including surface, cytoplasmic and nuclear proteins, DNA, RNA, reactive oxygen species, intracellular pH and calcium flux. Measurement of the expression of cellular activation markers, intracellular cytokines, immunological signaling, cytoplasmic and nuclear cell cycle and transcription factors can also be readily performed. In the tissue-engineering field, FCM can analyze cell proliferation and other critical biological and functional properties of cells. Clinically, FCM is used to analyze a wide array of immunological parameters in disease. Following treatment, FCM can be used to study the humoral and cellular response to vaccines and a variety of other clinically relevant cellular data. Major clinical uses that require multiple samples per patient include the diagnosis and monitoring of leukemia and lymphoma patients, the evaluation of peripheral blood hematopoietic stem cell grafts, and the quantitation of CD4+ vs. CD8+ T lymphocytes in blood to monitor HIV infection and assess the performance of treatment. FCM is also commonly used for measuring the total DNA content per cell in biopsy specimens from tumors for clinical cancer diagnosis and prognosis. Cytometers can also function to determine particle size and shape. =20 =20 Cheers, Ryan =20 =20 =20 =20 From: Daniel Schober [mailto:sc...@eb...]=20 Sent: Tuesday, July 03, 2007 7:26 AM To: frank gibson Cc: Ryan Brinkman; obi...@li...; obi...@li...

Hi Ryan, Excelent question and example. For my money, you describe what the flow cytometer actually does, not how we use it. They do stuff with particles suspended in a fluid, including sorting and counting. Unless the instrument itself does different things to cells vs other particles, it's probably not that useful to say much more. I think that's the function. Then there are a load of 'typical' processes describing how you use it. E.g. in a cell-counting process, there would be inputs including an instrument flow_cytometer and a sample containing cells in suspension, and the outputs including a count of the cells, or those cells sorted into different fractions by size or whatever. I guess we have a more general class of processes that involve a flow cytometer - it must have an instrument input flow cytometer, and a sample input 'suspension of microscopic particles'. Related question - can we define things like 'suspension of microscopic particles' in the biomaterials branch yet? There's a bunch of great definitions and names for these guys reachable from wikipedia http://en.wikipedia.org/wiki/Suspension_(chemistry) . I'm guessing that materials are linked into these mixtures by roles - since we use words like solvent, slute, and so on. The reason I sudgest modelling this that it gives us loads of extra constraints to validate experimental protocols via. For example, if someone claims to have feed a flow cytometer a solid lump of wood as the sample, and also know that the sample must be a liquid, then we can discover that something is up.
