产品描述:
The human Transthyretin (TTR) ELISA kit is suitable for the quantitative determination of human TTR in different sample types, including serum, plasma, and tissue homogenates. This assay employs the competitive inbition reaction and enzyme-substrate chromogenic reaction to quantify antigen levels in the sample. The amount of synthesized colored products is positively related to the analyte of interest in the sample.
TTR is a tetrameric transport protein that is synthesized in the liver, choroid plexus, and retinal pigment epithelium and then secreted into the bloodstream, cerebrospinal fluid (CSF), and eye, respectively. It is responsible for the transport of the thyroid hormone thyroxine and the RBP bound to retinol (vitamin A). TTR is the key protein in familial amyloid polyneuropathy (FAP), a systemic amyloidosis characterized by the deposition of amyloid derived from mutated TTR. It has recently discovered novel functions of TTR, including neuronal health preservation of both central and peripheral nervous systems, determination of cellular fate, and regulation of proliferation and metabolism.

- serum prealbumin, and its changes were independent predictors of worse prognosis in acute kidney injury (AKI), and could be potential surrogates to better predict 90-day mortality. PMID: 28145481
- T139R mutation may expose the buried regions of TTR protein which help in the self association and the increase in the stability may help in the TTR deposition. Structural analysis indicated that F and H strands of TTR are more prone to aggregation. Thus, T139R mutation might cause these residues to be aggregation prone and change in folding rate and validated TTR monomer in diseased cases by Western blot analysis. PMID: 29564986
- High TTR expression is associated with hypertriglyceridemia. PMID: 29747616
- Our study characterizes G101S TTR as a stable and N-glycosylable TTR, which may be linked to its non-amyloidogenic characteristic. G101S TTR had slower rate of tetramer dissociation and lower propensity for amyloid fibril formation, especially at mild low pH (4.2 and 4.5), and was likely to have strong hydrophobic interaction among TTR monomers, suggesting relatively higher stability of G101S TTR compared with WT TTR. PMID: 29607936

- Results indicate that TTR stability is important for its recently described functions in assisting Abeta transport at the BBB and at the liver and also in regulating LRP1 levels and activity. TTR stabilization can serve as an avenue to increase both Abeta elimination and LRP1 levels, which in turn will further participate in Abeta clearance. PMID: 28570028

- Clinical, electrophysiological, histopathological, and genetic characteristics of 17 patients from Turkey (5 female, 13 male) from nine families with polyneuropathy and mutations in TTR were evaluated. Sequence analysis of the TTR gene revealed five mutations (Val30Met, Glu89Gln, Gly53Glu, Glu54Gly and Gly47Glu). Study suggests that a cohort of patients from Turkey with TTR-FAP exhibits clinical and genetic heterogeneity. PMID: 27238058

PMID: 28920433

- In the bound state, the Hsp90 dimer predominantly populates an open conformation, and transthyretin retains its globular structure. PMID: 28218749
- findings show that, at physiologically-relevant protein concentrations, the refolding pathways of WT-TTR and amyloidogenic variant V30M-TTR follow a common mechanism observed among other tetrameric proteins; although sharing the same kinetic mechanism, V30M-TTR refolds at a slower rate than WT-TTR, a feature that may favor the formation of transient species leading to kinetic partition into amyloidogenic pathways PMID: 27589730
