Incorporate well-characterized compounds with known, consistent effects into every separate experimental group. These "anchors" act as internal calibration points, enabling reliable comparison of results across different experimental sets that would otherwise be difficult to correlate directly.
When designing multi-factor experiments, group compounds by their biological function. This prevents a dominant compound from overwhelming the signals of others and keeps dilution effects manageable. It ensures you capture the subtle effects of all factors, leading to more reliable and informative results.
While optimizing for a primary quality attribute like glycan profile, always measure secondary metrics such as aggregation and charge variance. The incremental cost is minimal since the cultures are already running, but the data can reveal critical, unforeseen effects that influence which candidates you advance.
Analyze high-dimensional data by first using PCA to visualize it in 2-3 dimensions. Then, calculate Mahalanobis distance to quantify each condition's closeness to a target. Finally, use a decision tree to identify which factors drive that closeness, creating simple, interpretable if-then rules for stakeholders.
