  • FunctionThyroid hormone-binding protein. Probably transports thyroxine from the bloodstream to the brain.
  • Tissue specificityDetected in serum and cerebrospinal fluid (at protein level). Highly expressed in choroid plexus epithelial cells. Detected in retina pigment epithelium and liver.
  • Involvement in diseaseDefects in TTR are the cause of amyloidosis transthyretin-related (AMYL-TTR) [MIM:105210]. A hereditary generalized amyloidosis due to transthyretin amyloid deposition. Protein fibrils can form in different tissues leading to amyloid polyneuropathies, amyloidotic cardiomyopathy, carpal tunnel syndrome, systemic senile amyloidosis. The disease includes leptomeningeal amyloidosis that is characterized by primary involvement of the central nervous system. Neuropathologic examination shows amyloid in the walls of leptomeningeal vessels, in pia arachnoid, and subpial deposits. Some patients also develop vitreous amyloid deposition that leads to visual impairment (oculoleptomeningeal amyloidosis). Clinical features include seizures, stroke-like episodes, dementia, psychomotor deterioration, variable amyloid deposition in the vitreous humor.
    Defects in TTR are a cause of hyperthyroxinemia dystransthyretinemic euthyroidal (HTDE) [MIM:145680]. It is a condition characterized by elevation of total and free thyroxine in healthy, euthyroid persons without detectable binding protein abnormalities.
    Defects in TTR are a cause of carpal tunnel syndrome type 1 (CTS1) [MIM:115430]. It is a condition characterized by entrapment of the median nerve within the carpal tunnel. Symptoms include burning pain and paresthesias involving the ventral surface of the hand and fingers which may radiate proximally. Impairment of sensation in the distribution of the median nerve and thenar muscle atrophy may occur. This condition may be associated with repetitive occupational trauma, wrist injuries, amyloid neuropathies, rheumatoid arthritis.
  • Sequence similaritiesBelongs to the transthyretin family.
  • DomainEach monomer has two 4-stranded beta sheets and the shape of a prolate ellipsoid. Antiparallel beta-sheet interactions link monomers into dimers. A short loop from each monomer forms the main dimer-dimer interaction. These two pairs of loops separate the opposed, convex beta-sheets of the dimers to form an internal channel.
  • Cellular localizationSecreted. Cytoplasm.

Application Western blot
We have used this product as a standard for Western blotting experiments examining prealbumin levels in biological fluids. Using native electrophoresis, we find that the protein runs to the expected molecular weight of approximately 55 kDa. Comparison to plasma-purified prealbumin shows a slight difference in migration, which is likely due to post-translational modifications not found on the recombinant protein. The protein has shown good stability following storage at -80 and also runs to the expected molecular weight during SDS-PAGE separation.

Electrophoretic separation shown in the figure was performed on 4-16% native Tris-Glycine gels. Proteins were subsequently transferred to PVDF membrane and blotted with anti-Prealbumin antibody [EP2929Y] (ab75815) at a dilution of 1:5,000. Bands were visualized with a goat-anti-rabbit IR Dye 800 secondary antibody at a 1:10,000 dilution. The image was collected on a Licor Odyssey CLx instrument.

Thank you for contacting us. I contacted the laboratory regarding your size issue and got the following responseThe size of our Prealbumin, 21-147aa, Human, Recombinant, E.coli is 13.8kDa. The small difference could be attributed to standard deviation...
