Cytochrome P450 4A/CYP4A11 Antibody

About the Target

CYP4A2 is a target of interest in many antibody-based workflows. Cytochrome P450 4A11 (CYP4A11) is a microsomal heme-containing monooxygenase, a human fatty acid ω-hydroxylase of the CYP4A subfamily, primarily expressed in the liver, kidney, and vasculature, where it catalyzes the ω-hydroxylation of fatty acids, most notably converting arachidonic acid into the vasoactive eicosanoid 20-hydroxyeicosatetraenoic acid (20-HETE). Structurally, like other P450s, CYP4A11 contains a conserved heme-thiolate center essential for oxygen activation, with cysteine-457 serving as the axial heme ligand that is dynamically regulated by the redox environment. Depending on the literature source, CYP4A2 may also be discussed as Cytochrome P450 4A/CYP4A11 and CYP4A11.

Reported cellular context includes endoplasmic reticulum, membrane, and microsome, which can matter when signal is compared across treatments or changing cell states. Following CYP4A2 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

CYP4A2 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 endoplasmic reticulum, membrane, and microsome, a defined reference condition can make comparisons more interpretable across perturbations, passages, or replicate sets.

Consider these angles when interpreting target-level changes:

• apparent redistribution between endoplasmic reticulum, membrane, and microsome across matched conditions
• 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 CYP4A2. 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 CYP4A2 reflect biology rather than handling. When interpreting CYP4A2, 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 CYP4A2 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.
