Serine/Glycine Deprivation Studies: Supports assays probing one-carbon metabolism, nucleotide synthesis, and redox balance by omitting serine and glycine.

Glucose-Free Metabolism Experiments: Enables evaluation of glycolytic dependence, Warburg effect, and glycolysis inhibitor responses with controlled carbon source add-back (e.g., galactose).

Stable-Isotope Tracing (13C/15N): Facilitates clean labeling experiments with 13C-glucose, 13C-serine, or 13C-glycine for metabolic flux analysis.

Nutrient Add-Back and Rescue Screens: Allows systematic reintroduction of glucose, serine, glycine, formate, or folate to identify pathway dependencies.

Auxotrophy and Pathway Characterization: Used to assess serine/glycine auxotrophies and engineered metabolic pathways in mammalian cells.

Process Development for Hematopoietic Cells: Applied to T cells, hybridomas, and other hematopoietic lines under defined carbohydrate and amino acid conditions.

Drug Mechanism and Sensitivity Testing: Optimizes evaluation of antifolates and one-carbon pathway inhibitors (e.g., SHMT, MTHFD) under targeted nutrient limitations.

Radiolabeled Uptake/Incorporation Assays: Provides a defined background for tracing labeled precursors into nucleotides and lipids.

Genetic Screens Under Nutrient Stress: Enables CRISPR/RNAi screens with glucose or serine/glycine restriction to reveal metabolic liabilities.

Bioenergetics and Mitochondrial Function Tests: Supports assays (e.g., Seahorse) to dissect glycolysis versus oxidative phosphorylation with controlled substrate add-back.
