Additional Info
Gene ID 2169
Gene Symbol FABP2
Other Names FABP2, FABPI, I-FABP
Gene Source Human
Source HEK293 cells
Assay&Purity SDS-PAGE; ≥98%
Assay2&Purity2 N/A;
Recombinant Yes
Results The binding affinity of Recombinant Human FABP2/I‑FABP for the synthetic ligand cis-parinaric acid has been measured by fluorescence titration. Half-maximal fluorescence of 3 µM Recombinant Human FABP2/I‑FABP is achieved with approximately 3 µM cis‑paranaric acid.
Target/Specificity FABP2 /I-FABP
Application Notes Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C.
Format Lyophilized
Storage -20°C; Lyophilized from 0.22 µm filtered solution in PBS, pH 7.4. Normally Mannitol or Trehalose is added as protectants before lyophilization.

Fatty acid-binding protein 2 (FABP2), is also known as Fatty acid-binding protein, intestinal (FABPI), Intestinal-type fatty acid-binding protein (I-FABP). FABP2 belongs to the calycin superfamily and Fatty-acid binding protein (FABP) family. FABP2 / FABPI is expressed in the small intestine and at much lower levels in the large intestine and is highest expressed in the jejunum. FABP are thought to play a role in the intracellular transport of long-chain fatty acids and their acyl-CoA esters. FABP2 is probably involved in triglyceride-rich lipoprotein synthesis. FABP2 binds saturated long-chain fatty acids with a high affinity, but binds with a lower affinity to unsaturated long-chain fatty acids. FABP2 may also help maintain energy homeostasis by functioning as a lipid sensor.
