The intracellular fatty acid-binding proteins (FABPs) belong to a multigene family with nearly twenty identified members.
FABPs are divided into at least three distinct types, namely the hepatic-, intestinal- and cardiac-type.
They form 14-15kD proteins and are thought to participate in the uptake, intracellular metabolism and/or transport of long-chain fatty acids.
They may also be responsible in the modulation of cell growth and proliferation.
Intestinal fatty acid-binding protein 2 gene contains four exons and is an abundant cytosolic protein in small intestine epithelial cells.
This gene has a polymorphism at codon 54 that identified an alanine-encoding allele and a threonine-encoding allele.
Thr-54 protein is associated with increased fat oxidation and insulin resistance.
Applications:Suitable for use in ELISA and Western Blot.
Other applications not tested.
Recommended Dilutions:ELISA: 1:64,000Western Blot: 0.001ug/mlOptimal dilutions to be determined by the researcher.
Positive Control:Human Duodenum lysates
Storage and Stability:May be stored at 4°C for short-term only.
For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20°C.
Aliquots are stable for at least 12 months at -20°C.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Further dilutions can be made in assay buffer.
Peptide Blocking:Corresponding peptide is available for Peptide Blocking studies.
See F0019-86C-P.
Antibody is typically 0.5mg/ml and peptide is supplied as a 100ul pellet.
When peptide is reconstituted in 200ul water, the concentration would also be 0.5mg/ml.
To start, the best ratio would be 1:1 (molar excess of peptide relative to antibody when identical volumes are mixed).
Mix equal volumes of peptide and antibody at the required dilution and leave at ambient temperature.
It is best is to have two identical blots to be incubated with equal amount of antibody, but one with the antibody pre-adsorbed to the peptide for 20min.
Then incubate and develop the two blots in parallel.
