• Tag: C-Myc/DDK
• Predicted MW: 46.4 kDa
• Concentration: >50 ug/mL as determined by microplate BCA method
• Purity: > 80% as determined by SDS-PAGE and Coomassie blue staining
• Buffer: 25 mM Tris.HCl, pH 7.3, 100 mM glycine, 10% glycerol
• Bioactivity: HNF4A Activity Verified in a DNA-binding Assay: HNF4A (TP317924, transcript variant 3) activity was measured in a colorimetric DNA-binding assay. Purified HNF4A protein containing a C-terminal MYC/DDK tag was incubated with biotinylated double-stranded oligonucleotide containing the HNF4A consensus DNA-binding sequence (see below). Following incubation, the reaction was transferred to a streptavidin-coated microplate to allow capture of the DNA-protein complex. After washing, the captured protein was detected with an anti-DDK peroxidase conjugate and colorimetric signal detection with TMB. Specificity of the protein-DNA interaction was confirmed by carrying out the binding in the presence of an unlabeled competitor oligonucleotide and by comparison to binding to an oligonucleotide containing a mutation in the consensus binding sequence.
• Preparation: Recombinant protein was captured through anti-DDK affinity column followed by conventional chromatography steps.
• Note: For culture applications, please filter before use. Note that you may experience some loss of protein during the filtration process.
• Storage: Store at -80°C.
• Stability: Stable for 12 months from the date of receipt of the product under proper storage and handling conditions. Avoid repeated freeze-thaw cycles.

• Summary: The protein encoded by this gene is a nuclear transcription factor which binds DNA as a homodimer. The encoded protein controls the expression of several genes, including hepatocyte nuclear factor 1 alpha, a transcription factor which regulates the expression of several hepatic genes. This gene may play a role in development of the liver, kidney, and intestines. Mutations in this gene have been associated with monogenic autosomal dominant non-insulin-dependent diabetes mellitus type I. Alternative splicing of this gene results in multiple transcript variants encoding several different isoforms. [provided by RefSeq, Apr 2012]
