Product Overview
This rabbit polyclonal antibody targets fatty acid-binding protein, intestinal (gene Fabp2) in mouse samples and is validated for ELISA. The predicted molecular weight is 15.1 kDa.
Intestinal fatty acid-binding protein (FABP2, I-FABP) is a small cytosolic protein in enterocytes of the small intestine. It binds long-chain fatty acids and is thought to support their uptake and packaging into triglyceride-rich lipoproteins. Because it leaks into blood when the gut lining is damaged, I-FABP is widely measured as a marker of intestinal epithelial injury.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
