CYP71A24 Antibody

What is CYP71A24 and what are its primary functions in plant metabolism?

CYP71A24 belongs to the cytochrome P450 superfamily, a diverse group of enzymes involved in metabolic processes. In plants, this enzyme plays critical roles in biosynthetic pathways of secondary metabolites. Like other P450 family members, CYP71A24 functions as a monooxygenase, catalyzing reactions that typically involve the insertion of an oxygen atom into various substrates . Understanding the enzyme's function provides context for antibody-based detection methods in research applications.

What are the key specifications to verify when selecting a CYP71A24 antibody?

When selecting a CYP71A24 antibody, researchers should verify:
