IDH2 Antibody

About the Target

Isocitrate dehydrogenase 2 (IDH2) is a mitochondrial enzyme that plays a pivotal role in cellular metabolism, particularly in the tricarboxylic acid (TCA) cycle, where it catalyzes the oxidative decarboxylation of isocitrate to α-ketoglutarate (α-KG), concurrently producing NADPH. IDH2 functions as a homodimer and belongs to the NADP⁺-dependent IDH family, localized in the mitochondrial matrix. Depending on the literature source, IDH2 may also be discussed as IDH and ICD-M.

Reported cellular context includes mitochondrion, which can matter when signal is compared across treatments or changing cell states. Following IDH2 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

IDH2 is commonly interpreted in the context of metabolism and oxidative stress research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans mitochondrion, a defined reference condition can make comparisons more interpretable across perturbations, passages, or replicate sets.

Consider these angles when interpreting target-level changes:

• signal enrichment within mitochondrion relative to the broader cellular background
• responses linked to nutrient status, mitochondrial state, or metabolic rewiring
• redox-associated shifts that may alter abundance, localization, or pathway coupling
• co-patterning with orthogonal markers and control conditions that clarify pathway state

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for IDH2. This can help when protocols evolve over time and the goal is to compare experiments using a stable reference workflow.

Standardize sampling time, control choice, and downstream analysis thresholds so apparent differences in IDH2 reflect biology rather than handling. When interpreting IDH2, it is often useful to decide early whether the main question is overall abundance, compartmental enrichment, or context-dependent redistribution.

For multi-run studies, a shared reference condition can keep IDH2 trends easier to compare across datasets. That kind of consistency is especially helpful when follow-up work expands to new perturbations, model systems, or longitudinal collections.
