Finally, as previously stated, if in vitro models are to be fully effective, the underlying mechanisms of ocular irritation need to be identified. Many of the in vitro assays proposed as alternatives to in vivo testing are based on correlations rather than mechanisms of irritation. The scoring or ranking of substances utilizing the in vitro endpoint may correlate with the severity of the in vivo response, but the reason for the agreement may be unclear and strictly fortuitous for the compounds evaluated. The ideal assay would monitor several biochemical or biological events specifically... 

The maintenance of desired phenotypic features over multiple generations will need to be periodically evaluated. If a feature is unstable over the experimental period, it will be necessary to evaluate other clones or generate new clones. If the phenotype changes as a result of multiple subcultures, earlier passages can be thawed (if they have been appropriately generated and stored) and utilized appropriately. Once the immortalized clones have been established and characterized for desired phenotypic features, they can then be used for numerous biochemical, molecular biological, and pharmacological studies. 

Enzymes are biological catalysts. Without their presence in a cell, most biochemical reactions would not proceed at the required rate. The physicochemical and biological properties of enzymes have been investigated since the early 1800s. The unrelenting interest in enzymes is due to several factors— their dynamic and essential role in the cell, their extraordinary catalytic power, and their selectivity. Two of these dynamic characteristics will be evaluated in this experiment, namely a kinetic description of enzyme activity and molecular selectivity. 

The evaluation of stability may necessitate complex analytical methodologies. Assays for biological activity, where applicable, should be part of the pivotal stability studies. Appropriate physico-chemical, biochemical, and immunochemical methods for the analysis of the molecular entity and the quantitative detection of degradation products should also be part of the stability program whenever purity and molecular characteristics of the product permit use of these methodologies.
