Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of mouse iFABP in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

(From Uniprot)
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.
Gene References into Functions
  1. This direct comparison provides evidence that LFABP and IFABP have distinct roles in intestinal lipid metabolism; differential intracellular functions in intestine and in liver PMID: 23990461
  2. detected the common as well as sex-differential pathways that are modified due to the loss of Fabp2. These findings suggest that the pathways involved in nutrient and xenobiotic metabolism in the intestine are regulated by sex-specific mechanisms PMID: 22584290
  3. loss of I-FABP renders male mice sensitive to high fat diet-induced fatty liver, and this effect is independent of hepatic L-FABP PMID: 17905650
Subcellular Location Cytoplasm
Protein Families Calycin superfamily, Fatty-acid binding protein (FABP) family
Tissue Specificity Expressed in the small intestine. Highest expression levels in the proximal ileum.
