Abstract: The present invention relates to methods, devices and systems for associating consumable data with an assay consumable used in a biological assay. Provided are assay systems and associated consumables, wherein the assay system adjusts one or more steps of an assay protocol based on consumable data specific for that consumable. Various types of consumable data are described, as well as methods of using such data in the conduct of an assay by an assay system. The present invention also relates to consumables (e.g., kits and reagent containers), software, data deployable bundles, computer-readable media, loading carts, instruments, systems, and methods, for performing automated biological assays.

Abstract: A process for determining genetic susceptibility to cancer is disclosed in which the frequency of chromatid breaks and gaps is calculated in metaphase skin fibroblasts or stimulated peripheral blood lymphocytes after x-irradiation or fluorescent light exposure. Susceptibility to cancer is found when the frequency of breaks and gaps in the cell sample is two to three-fold higher than that occurring in comparable cells from control individuals. Various factors have been found which influence the accuracy of the test results. These factors include pH, temperature, cell density, culture medium or serum, microbial contamination and visible light exposure (effective wavelength 500 nm). Additionally, because of experimental variability, known normal controls are suggested for use in each test group.
