Detection of Mouse FABP2/I‑FABP by Western Blot. Western blot shows lysates of mouse small intestine tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Mouse/Rat FABP2/I‑FABP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1486) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for FABP2/I‑FABP at approximately 14 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
FABP2/I‑FABP in Rat Mesenchymal Stem Cells. FABP2/I‑FABP was detected in immersion fixed rat mesenchymal stem cells differentiated to adipocytes using Goat Anti-Mouse/Rat FABP2/I‑FABP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1486) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

FABP2/I‑FABP in Mouse Intestine. FABP2/I‑FABP was detected in immersion fixed frozen sections of adult mouse intestine using Goat Anti-Mouse/Rat FABP2/I‑FABP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1486) at 10 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to intestinal epithelia. View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

FABP2, also named I-FABP and gFABP, is a member of the intracellular
fatty acid binding protein family. It is highly expressed in the
intestine. FABP2 binds fatty acid in a non-covalent 1:1 complex to
chaperone the lipids to cellular enzymes for metabolism and signal
