General Notes
This product (Catalog No. DPABH-09097) is a rabbit-derived polyclonal antibody raised against human FABP3, targeting the amino acid region 1–133 of the protein. This antibody exhibits cross-reactivity with Human FABP3 from mouse and rat. It has been affinity purified by Protein A. FABP3 (fatty acid binding protein 3), also known as heart-type fatty acid–binding protein (H-FABP), is a small (~15 kDa) cytoplasmic lipid chaperone that belongs to the fatty acid–binding protein family. It is highly expressed in cardiac and skeletal muscle, where it binds long-chain fatty acids and facilitates their intracellular transport to sites of β-oxidation, lipid storage, or membrane synthesis. By regulating fatty acid uptake, trafficking, and metabolic channeling, FABP3 plays a key role in myocardial energy homeostasis. Clinically, due to its rapid release into the bloodstream following myocardial injury, FABP3 has been used as an early biomarker for acute myocardial infarction. Beyond cardiac tissue, altered FABP3 expression has also been linked to metabolic disorders and certain cancers, reflecting its broader involvement in lipid metabolism and cellular energy regulation.
DPABH-09097 is suitable for use in ELISA (1:4,000–1:8,000), IHC (1:50–1:100), Western blot (WB) (1:1,000–1:4,000) applications.
DPABH-09097 is supplied as a liquid formulation in 0.01M PBS, pH 7.4, 50% Glycerol, 0.05% Proclin 300. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
