Product Overview
Clone 24F95 is a rabbit monoclonal antibody that recognizes fatty acid-binding protein, intestinal (gene FABP2) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 15.2 kDa, and the supplier reports an observed band at about 15 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.

Samples with a confirmed band (WB): human small intestine.
Recommended loading (WB): 20–40 µg of total protein per lane.
Immunogen
Synthetic peptide based on the sequence of human FABPI.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places fatty acid-binding protein, intestinal in the cytoplasm. Tissue expression noted by UniProt (human): Expressed in the small intestine and at much lower levels in the large intestine. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

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).
