This assay has high sensitivity and excellent specificity for detection of Transthyretin (TTR). No significant cross-reactivity or interference between Transthyretin (TTR) and analogues was observed.

The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Typical Testing Data/Standard Curve (for reference only)

Assay Type: Double-antibody Sandwich. Samples: Serum, Plasma, Tissue homogenates, Cell lysates, Cerebrospinal fluid, Cell culture supernates and Other Biological Fluids. Detection Range: 0.312-20ng/mL. Sensitivity: < 0.151ng/mL

Application: Enzyme-linked immunosorbent assay for Antigen Detection. Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Transthyretin (TTR) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Transthyretin (TTR) were tested on 3 different plates, 8 replicates in each plate. CV(%) =: SD/meanX100. Intra-Assay: CV<10%. Inter-Assay: CV<12%

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Transthyretin (TTR). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Transthyretin (TTR). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Transthyretin (TTR), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm 10nm. The concentration of Transthyretin (TTR) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

This gene encodes transthyretin, one of the three prealbumins including alpha-1-antitrypsin, transthyretin and orosomucoid. Transthyretin is a carrier protein; it transports thyroid hormones in the plasma and cerebrospinal fluid, and also transports retinol (vitamin A) in the plasma. The protein consists of a tetramer of identical subunits. More than 80 different mutations in this gene have been reported; most mutations are related to amyloid deposition, affecting predominantly peripheral nerve and/or the heart, and a small portion of the gene mutations is non-amyloidogenic. The diseases caused by mutations include amyloidotic polyneuropathy, euthyroid hyperthyroxinaemia, amyloidotic vitreous opacities, cardiomyopathy, oculoleptomeningeal amyloidosis, meningocerebrovascular amyloidosis, carpal tunnel syndrome, etc. [provided by RefSeq, Jan 2009]

TTR: Thyroid hormone-binding protein. Probably transports thyroxine from the bloodstream to the brain. Defects in TTR are the cause of amyloidosis transthyretin-related (AMYL-TTR). 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). 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). 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. Belongs to the transthyretin family. Protein type: Secreted; Secreted, signal peptide. Chromosomal Location of Human Ortholog: 18q12.1. Cellular Component: extracellular space; protein complex; cytoplasm; extracellular region.
