A 96-well assay for measurement of SREBP-1.
- A sensitive, non-radioactive method of detecting SREBP-1 from whole cell lysates
- 96-well plate format replaces EMSAs
- Capture the transcription factor using a specific dsDNA sequence bound to the plate
- Detect the dsDNA-bound transcription factor with specific antibodies in an ELISA format
- Nuclear extraction kit is available to aid in the isolation of nuclear and cytoplasmic fractions from cell lysates or tissue homogenates
Three known isoforms of SREBP (sterol regulatory element binding protein) transcription factors have been characterised: SREBP-1a, SREBP-1c, and SREBP-2. SREBP-1c acts primarily to activate genes required for fatty acid synthesis, such as acetyl CoA carboxylase, fatty acid synthase, and long chain fatty acid elongase. In addition, SREBP-1c may also contribute to the regulation of glucose uptake and synthesis through induction of glucokinase. SREBP-1c has important clinical implications in the treatment of many diseases including obesity, diabetes mellitus, insulin resistance, and non-alcoholic fatty liver disease (NAFLD). Cayman’s SREBP-1 Transcription Factor Assay is a non-radioactive, sensitive method for detecting specific transcription factor DNA binding activity. SREBP-1 contained in nuclear extracts and whole cell lysates binds to a dsDNA SREBP response element immobilized to the wells of a 96-well plate. SREBP-1 is detected by addition of a specific primary antibody directed against SREBP-1. A secondary antibody conjugated to HRP is used to provide a sensitive colorimetric readout at 450 nm.
Lieferumfang: Kit contains assay buffer, reagent a, positive control, binding buffer, primary antibody, wash buffer concentrate, polysorbate 20, competitor dsDNA, HRP conjugate, plate and cover sheet, developing and stop solution.
