Description
Boster Bio Anti-FABP2/I-FABP Antibody Picoband® catalog # A02378. Tested in IHC, WB applications. This antibody reacts with Human, Mouse, Rat. The brand Picoband indicates this is a premium antibody that guarantees superior quality, high affinity, and strong signals with minimal background in Western blot applications. Only our best-performing antibodies are designated as Picoband, ensuring unmatched performance. FABP2 (intestinal fatty acid–binding protein; I-FABP) is described as an abundant cytosolic protein in small-intestine epithelial cells and part of a multigene FABP family. Assay context: antibody validated for IHC and WB; reactive to Fabp2 in human/mouse/rat; immunogen is E. coli–derived mouse FABP2 recombinant protein (A2–E132) with reported observed MW ~15 kDa and stated no cross-reactivity. Often used as an enterocyte/epithelial integrity marker (putative) and can be interpreted alongside remodeling readouts such as COL1A1 or POSTN in injury–repair contexts (putative); protein-level confirmation commonly leverages western blotting or tissue localization via IHC (putative).
Storage & Handling

Background of Fabp2
FABP 2, Fatty acid-binding protein 2, is a protein that in humans is encoded by the FABP2 gene. Using a human cDNA probe, the gene is assigned to chromosome 4 in somatic cell hybrids. FABP 2 gene contains four exons and is an abundant cytosolic protein in small intestine epithelial cells. The FABPs belong to a multigene family with nearly twenty identified members. And FABPs are divided into at least three distinct types, namely the hepatic-, intestinal- and cardiac-type. They form 14-15 kDa proteins and are thought to participate in the uptake, intracellular metabolism and/or transport of long-chain fatty acids. Also, they may be responsible in the modulation of cell growth and proliferation.

Western blot analysis of FABP2/I-FABP using anti-FABP2/I-FABP antibody (A02378).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions.
Lane 1: rat liver tissue lysates,
Lane 2: rat small intestine tissue lysates,
Lane 3: mouse liver tissue lysates,
Lane 4: mouse small intestine tissue lysates.
After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-FABP2/I-FABP antigen affinity purified polyclonal antibody (Catalog # A02378) at 0.5 μg/mL overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for FABP2/I-FABP at approximately 15 kDa. The expected band size for FABP2/I-FABP is at 15 kDa.

IHC analysis of FABP2/I-FABP using anti-FABP2/I-FABP antibody (A02378).
FABP2/I-FABP was detected in paraffin-embedded section of mouse intestine tissues. Heat mediated antigen retrieval was performed in citrate buffer (pH6, epitope retrieval solution) for 20 mins. The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 1μg/ml rabbit anti-FABP2/I-FABP Antibody (A02378) overnight at 4°C. Biotinylated goat anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37°C. The tissue section was developed using Strepavidin-Biotin-Complex (SABC)(Catalog # SA1022) with DAB as the chromogen.
