|Product name||Human Transcription termination factor 1 (TTF1) ELISA Kit|
|Applications notes||This Human Transcription termination factor 1 (TTF1) ELISA Kit employs a two-site sandwich ELISA to quantitate TTF1 in samples. An antibody specific for TTF1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTTF1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TTF1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TTF1 bound in the initial step. The color development is stopped and the intensity of the color is measured.|

|Usage notes||• Do not mix components from different kit lots or use reagents beyond the kit expiration date.
• Allow all reagents to warm to room temperature for at least 30 minutes before opening.
• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.
• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
• It is recommended that all samples and standards be assayed in duplicate or triplicate.
|Storage instructions||The unopened kit should be stored at 2 - 8°C. After opening, please store refer to protocols.|
|Shipping||Gel pack with blue ice.|

|Background||TTF2 has been shown to have dsDNA-dependent ATPase activity and RNA polymerase II termination activity. This protein interacts with cell division cycle 5-like, associates with human splicing complexes, and plays a role in pre-mRNA splicing.The deduced 990-amino acid TTF2 protein shares 43% amino acid sequence identity with Drosophila factor 2. These proteins contain 7 motifs found in helicase superfamilies 1 and 2; 7 additional motifs shared only by SWI2/SNF2 family members; and 3 conserved motifs and a nuclear localization signal that are not conserved among the SWI2/SNF2 family. Similar to Drosophila factor 2, recombinant human TTF2 displayed a strong double-stranded DNA-dependent ATPase activity that was inhibited by single-stranded DNA and exhibited RNA polymerase II termination activity.|
