Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E.coli-derived human Prealbumin recombinant protein (Position: G21-E147). Human Prealbumin shares 81% and 83.3% amino acid (aa) sequence identity with mouse and rat Prealbumin, respectively. (reported region: G21-E147).
- Molecular weight context: reported MW: 14 kDa; calculated MW: 15887 MW
- Reactivity: Human
- Applications: ELISA, IHC, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
Transthyretin; Transthyretin. Transthyretin (TTR) is also known as prealbumin. It is mapped to chromosome region 18q11.2-q12.1. This gene encodes a carrier protein responsible for the transport of thyroid hormones and retinol. The protein consists of a tetramer of identical subunits. Due to increased stability of the tetramer form of this encoded protein in mouse, compared to the human protein, this gene product has a reduced tendency to form amyloid fibrils. In humans, this protein binds beta-amyloid preventing its aggregation and providing a neuroprotective role in Alzheimer's disease. Functional note: Thyroid hormone-binding protein. Probably transports thyroxine from the bloodstream to the brain. . Reported localization: Secreted. Cytoplasm. Expression/tissue context: Detected in serum and cerebrospinal fluid (at protein level). Highly expressed in choroid plexus epithelial cells. Detected in retina pigment epithelium and liver. .
Research relevance and current trends
- Alzheimer's Disease: Researchers commonly examine how TTR (Transthyretin) relates to this theme using model systems and orthogonal readouts.
- Cardiovascular: Researchers commonly examine how TTR (Transthyretin) relates to this theme using model systems and orthogonal readouts.
- Neurodegenerative Disease: Researchers commonly examine how TTR (Transthyretin) relates to this theme using model systems and orthogonal readouts.
Common research applications
- Western blotting: compare relative TTR (Transthyretin) levels across conditions; band patterns may reflect isoforms and processing.
- IHC/IHC-F: assess spatial distribution of TTR (Transthyretin) across tissue regions and cell types using matched controls.
- ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
