The overall workflow of ADME/Tox characterization of lead compounds is typically distributed across multiple departments or functional groups within pharmaceutical companies, often with specialized groups for different assays, analysis and interpretation. A representation of the overall workflow is provided in Figure 1.1. 

Assay. Analysis of the active ingredient, whether by chemical or biological methods, would be the same for the constituted product as that necessary for any ready-to-use preparation. Constituted solution, however, have a limited shelf life after addition to the diluent. Depending on the solution stability, the... 

Cultured cells are treated with various doses of test substances in varying time periods. After the completion of treatment, they are harvested and lysed. The lysates are analyzed for p53 by Western blot and/or enzyme-linked immunosorbent assay analysis. An increase in cellular p53 following treatment is interpreted...

After a method has been validated, it can be used for routine laboratory analyses. There may be additional analytical considerations that are important in routine assays. Analysis of the specimens should be done in a timely manner, especially when the analyte is unstable.

The biosensor and response system used a tiered approach. Samples of airborne biological material were taken continuously by the Joint Biological Point Detection System (JBPDS) equipment, which was not commercially available. Operation of these systems was monitored continuously at a separate control facility. Initial detection by the JBPDS equipment was followed by a second-tier assay analysis that, if positive, would result in physical collection of sampled material for additional analysis off-site. The confirmed second-tier analysis would result in notification of JBPDS leadership and shipment of a sample to the Utah Department of Health for further laboratory analysis. Because the confirmatory test would take 12-24 hours to complete, the primary function of the higher-tiered detection was to define treatment and decontamination responses (LP-3 options). Change in building or HVAC operation on the fifth and sixth floors would not be initiated until the Utah Department of Health analysis confirmed detection of a biological threat agent.

In addition, availability of data collection and analysis systems or laboratory information management systems (LIMS), with or without a data analysis package, at the receiving laboratory will determine how assay analysis and data transfer can be accomplished. There is a significant chance that data analysis, processing systems and LIMS are different between laboratories. In these cases, comparability of the results from the data analysis should be verified early on. It should be determined whether the calibration curve algorithm is the same in both labs. If they are different, it needs to be verified that the data analysis leads to comparable results. It is also important that the data can be transferred between labs in a compatible format, for example, to allow transfer to an SAS database. 

Confirmation of ricin inhalational intoxication would most likely be through enzyme-linked immunosorbent assay analysis of a swab sample from the nasal mucosa ricin can be identified by this method for at least 24 hours after the challenge.49 Because ricin is extremely immunogenic, individuals surviving a ricin attack would likely...
