Immunofluorescent analysis of Thyroid Hormone Receptor in HepG2 Cells. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with a Thyroid Hormone Receptor monoclonal antibody (Product # MA1-215) at a dilution of 1:20 overnight at 4 C, washed with PBS and incubated with a DyLight-488 conjugated secondary antibody (Product # 35503). Thyroid Hormone Receptor staining (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Images were taken at 60X magnification.

MA1-215 detects thyroid hormone receptor (TR) from human tissues. This antibody recognizes TR beta-1 and also cross-reacts with TR alpha-1.
MA1-215 has been successfully used in Western blot, IF, immunoprecipitation, and gel shift procedures. By Western blot, this antibody detects a 55 and a 52 kDa protein representing recombinant human TR beta-1 expressed in E. coli. MA1-215 immunoprecipitates 52 kDa and 55 kDa proteins, representing TR beta-1 and a 48 kDa protein representing TR alpha-1 expressed in E. coli.
The MA1-215 immunogen is a purified fragment of human TR beta-1 corresponding to amino acid residues 201-456. This antibody recognizes an epitope in the hormone binding domain of hTR beta-1, amino acid residues 235-414. This sequence is conserved in hTR alpha-1.
Thyroid hormone receptors (TR) are ligand-dependent, intracellular proteins that stimulate transcription of specific genes by binding to specific DNA sequences called hormone response elements following activation by the appropriate hormone. Thyroid hormones, through their interaction with TR, effect metabolic processes, growth and development in many tissues by regulating the expression of genes for growth hormone, malic enzyme and several hepatic proteins. There are two forms of TR; TR alpha (on chromosome 17) and TR beta (on chromosome 3). Each of these isoforms also has two isoforms; TR alpha-1 and TRv alpha-2, and TR beta-1 and TR beta-2 respectively. TR alpha-1 and 2 are identical through amino acid 370 where their sequences diverge. TRv alpha-2, which does not bind T3 and is a strong negative regulator of the functional TR, is 80 amino acids longer than TR alpha-1.
