Transthyretin (TTR) ELISA Kits
Separate kits are available for human, mouse, rat. 96T
Fully guaranteed to meet specifications
Introduction:
TTR misfolding and aggregation is known to be associated with thee amyloid diseases senile systemic amyloidosis (SSA), familial amyloid polyneuropathy (FAP), and familial amyloid cardiomyopathy (FAC). Transthyretin tetramer dissociation is known to be rate-limiting for amyloid fibril formation. However, the monomer also must partially denature in order for TTR to be mis-assembly competent, leading to a variety of aggregate structures, including amyloid fibrils. TTR is also thought to have beneficial side effects, by binding to beta-amyloid protein, thereby preventing beta-amyloid's accumulation into the plaques associated with the early stages of Alzheimer's Disease.

Linearity
|
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of TTR and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
