Product Overview
This rabbit polyclonal antibody detects transthyretin (gene Ttr) in mouse and rat samples and is validated for ICC/IF, IHC and Western blot. The predicted molecular weight is 15.7 kDa, and the supplier reports an observed band at about 16 kDa.
Transthyretin (TTR) is a tetrameric transport protein made mainly by the liver and the choroid plexus. It carries thyroxine in blood and cerebrospinal fluid and transports retinol by binding retinol-binding protein. Destabilized TTR can misfold into amyloid fibrils, causing transthyretin amyloidosis.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL (Mouse, Rat) |
| Immunocytochemistry / Immunofluorescence | 5 µg/mL (Mouse, Rat) |
Samples with a confirmed band (WB): rat liver tissue, rat kidney tissue, mouse liver tissue, mouse kidney tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:10000, ECL detection.
Samples with confirmed staining (IHC): mouse pancreas tissue, rat kidney tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): mouse pancreas tissue, rat kidney tissue.
Immunogen
Recombinant rat Prealbumin fragment (Gly21–Asn147), expressed in E. coli. Sequence identity with the mouse ortholog: 94.5%.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt describes transthyretin as a secreted protein. Tissue expression noted by UniProt (rat): Detected in serum and cerebrospinal fluid (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
