THRA Antibody

Rabbit Polyclonal

Western blot using Rockland's affinity purified anti-THRA antibody shows detection of purified recombinant THRA (lane 1) and THRA present in a 293 cell lysate after transient transfection with THRA (lane 3). No staining is evident in lysates from mock-transfected 293 cells (lane 2). Endogenous THRA is not detected in mouse brain whole cell lysate (lane 4). Nuclear extracts may be required to detect endogenous THRA as the protein localizes within the nucleus. The band at ~55 kDa, indicated by the arrowhead, corresponds to THRA.

THRA Antibody Description

Background
This antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. Thyroid hormone receptor alpha is a nuclear hormone receptor with high affinity for the hormone triiodo-thyronine.  THRA is one of the several receptors for thyroid hormone, and has been shown to mediate the biological activities of thyroid hormone. Knockout studies in mice suggest that the different receptors, while having a certain extent of redundancy, may mediate different functions of thyroid hormone.  THRA interacts with NCOA3 and NCOA6 co-activators, leading to a strong increase in transcription of target genes. THRA is localized within the nucleus and has been found to exist as 4 isoforms originating from alternative splicing variants.  Isoform 1 has a distinct C-terminus compared to isoform 2.
Synonyms
Thyroid hormone receptor alpha Nuclear receptor subfamily 1 group A member 1 c-erbA-alpha c-erbA-1 V-erbA-related protein 7 EAR-7 TRa1
Immunogen
This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to a region near the amino terminus of human THRA isoform 1 protein.
Immunogen Type
Peptide
Storage Condition
Store vial at -20° C or below prior to opening. This vial contains a relatively low volume of reagent (25 µL). To minimize loss of volume dilute 1:10 by adding 225 µL of the buffer stated above directly to the vial. Recap, mix thoroughly and briefly centrifuge to collect the volume at the bottom of the vial. Use this intermediate dilution when calculating final dilutions as recommended below. Store the vial at -20°C or below after dilution. Avoid cycles of freezing and thawing.
Application Note
This affinity purified antibody has been tested for use in ELISA and western blotting.
Purity/Specifity
This product was affinity purified from monospecific antiserum by immunoaffinity chromatography. This antibody reacts with human THRA protein and recognizes THRA isoform 1. A BLAST analysis was used to suggest cross-reactivity with THRA from mouse, human and rat based on a 100% homology with the immunizing sequence.  Cross-reactivity with THRA from other sources and isoforms may occur but has not been determined.
