This assay has high sensitivity and excellent specificity for detection of TSTA3. No significant cross-reactivity or interference between TSTA3 and analogues was observed.

Store at 4 degree C if kit is to be used within 1 week. Stable for 6 months (if micro ELISA Plate, Lyophilized Standard and Concentrated Biotinylated Detection Protein stored at-20 degree C. Other components at 2-8 degree C). Stable for 12 months (if the entire kit is stored at-20 degree C).

Typical Testing Data/Standard Curve (for reference only)

Samples: Serum, Plasma, Tissue Homogenates And Other Biological Fluids. Assay Type: Sandwich. Detection Range: 0.156-10ng/ml. Sensitivity: <0.094ng/ml

Intra-assay Precision: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level TSTA3 were tested 20 times on one plate, respectively. Intra-Assay: CV<8%. Inter-assay Precision: Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level TSTA3 were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100. Inter-Assay: CV<10%

Principle of the Assay: This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-TSTA3 antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-TSTA3 antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and washed with wash buffer. HRP-Streptavidin was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the TSTA3 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of TSTA3 can be calculated.

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, signal peptide; Secreted. Chromosomal Location of Human Ortholog: 18q12.1. Cellular Component: cytoplasm; extracellular region; extracellular space; protein complex.
