  • Product overview

    Abcam's FABP2 Human ELISA Kit (ab193700) is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of human FABP2 in sera, plasma and cell culture supernatants.

    This assay employs an antibody specific for human FABP2 coated on a 96-well plate. Standards and samples are pipetted into the wells and the immobilized antibody captures FABP2 present in the samples. The wells are washed and biotinylated anti-human FABP2 antibody is added. After washing away any unbound biotinylated antibody, an HRP-conjugated streptavidin is pipetted to the wells. After incubation, the wells are again washed, followed by the addition of a TMB substrate solution to the wells. Color will develop in proportion to the amount of FABP2 bound in each well. Addition of the Stop Solution will change the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • Function
    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. 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.
  • Tissue specificity
    Expressed in the small intestine and at much lower levels in the large intestine. Highest expression levels in the jejunum.
  • Sequence similarities
    Belongs to the calycin superfamily. Fatty-acid binding protein (FABP) family.
  • Domain
    Forms a beta-barrel structure that accommodates the hydrophobic ligand in its interior.

Customer reviews and Q&As

After trying numerous porcine-specific ELISAs for FABP2, I decided to risk trying this ELISA in hopes that it would give satisfactory results. As the title says, it works well with a good standard curve and a very low background. My samples were diluted 1:1 with the sample dilution buffer provided, which yielded good results.

Duplication of samples were very close, and there were no problems with the plate.

As an aside, the standard curve in the mixture was not plated in order, so it appears incorrect, however it worked quite well.
