• Species Reactivity

  Mouse, Rat

• Specificity

  Detects mouse and rat FABP2/I‑FABP in Western blots. Detects rat FABP2/I‑FABP in direct ELISAs. In direct ELISAs and Western blots, less than 5% cross-reactivity with recombinant rat FABP1, recombinant human FABP3, recombinant mouse (rm) FABP4, and rmFABP5 is observed.

Background: FABP2/I-FABP

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 transduction.

• Long Name:

  Fatty Acid-Binding Protein 2/Intestinal FABP

• Entrez Gene IDs:

  2169 (Human); 25598 (Rat)

• Alternate Names:

  FABP2; FABPI; fatty acid binding protein 2, intestinal; Fatty acid-binding protein 2; fatty acid-binding protein, intestinal; IFABP; I-FABP; I-FABPMGC133132; Intestinal FABP; Intestinal-type fatty acid-binding protein
