Product Background

Constitutive androstane receptor (CAR, NR1I3) is a ligand-activated nuclear receptor involved in xenobiotic metabolism, drug detoxification, lipid metabolism, and hepatic gene regulation. CAR plays an important role in regulation of cytochrome P450 enzymes, liver metabolism, inflammation, and toxicological responses. CAR is widely studied in pharmacology, metabolism, toxicology, and liver biology research.

Antibody Development

MM0006 was generated by phage-display selection using a mouse-derived antibody library. Recombinant epitope-Fc fusion protein containing the target epitope sequence was used as the selection antigen. Following identification of the initial antibody candidate, structure-guided affinity optimization was performed to improve binding affinity and specificity.

The optimized antibody was reconstructed as a full-length mouse IgG1 recombinant antibody and expressed in HEK293 cells.

Binding and specificity were evaluated by:

• ELISA using recombinant epitope-Fc fusion antigen
• Western blot detection of endogenous mouse CAR protein in mammalian tissue and cell lysates
• Cross-reactivity analysis demonstrating recognition of human CAR protein

Validation Data

ELISA Validation

ELISA demonstrated specific binding to recombinant epitope-Fc fusion antigen, while minimal binding was observed against Fc control protein.

Validation conditions:

• Well 1: Fc control protein
• Well 2: epitope-Fc fusion protein
• Detection substrate: TMB

Note: ELISA validation confirms binding to the epitope-Fc fusion antigen. Full-length CAR protein binding in solution has not been tested by ELISA.

Western Blot Validation – Endogenous Full-Length Protein

Western blot analysis detected endogenous CAR protein in mammalian tissue and cell lysates under reducing conditions.

Validated samples:

• HEK293T cells
• Lung tissue
• Brain tissue

Detection condition:

• Standard reducing Western blot
• HRP-conjugated anti-mouse secondary antibody

MM0006 also demonstrated cross-reactivity with human CAR protein.
