Product Information
Product Usage Information
(a) Wash membrane-bound HRP (antibody conjugate) three times, for 5 minutes in TBS/T.
(b) Prepare substrate by diluting 20X LumiGLO® and 20X Peroxide to 1X in water (e.g. for 10 ml, add 0.5 ml LumiGLO® and 0.5 ml peroxide to 9.0 ml water).
(c) Incubate substrate with membrane for 1 minute, remove excess solution (membrane remains wet), wrap in plastic and expose to X-ray film.
Solutions and Reagents
Prepare solutions with Milli-Q® or equivalently purified water.Wash Buffer (TBS/T): 20 mM Tris-HCl (pH 7.6),137 mM NaCl and 0.1% Tween-20Advantages of the Phototope® Western Detection System-Sensitivity: Detection of sub-picogram amounts of protein is routine with good primary antisera.-Speed: Less than 1 hour is required for the entire detection procedure. Exposure times are seconds to minutes.-Multiple Exposures: Light is emitted at a constant rate for several minutes, so you can perform multiple exposures to optimize signal intensity. Re-exposure at a future date is achieved by simply adding more reagent.
Storage
Method Overview
There are six basic steps in the Western blotting procedures with the Phototope®-HRP Western Blot Detection System.
- Polyacrylamide Gel Electrophoresis of Proteins: Separate the protein samples and molecular weight standards by polyacrylamide gel electrophoresis.
- Transfer: Transfer the protein to membrane by standard electroblotting.
- Block Membrane: Block to saturate nonspecific binding sites on the membrane.
- 1° Antibody: Incubate the membrane with the primary antibody.
- 2° Antibody: Incubate the membrane with HRP-linked anti-rabbit IgG and HRP-linked anti-biotin antibodies.
- Chemiluminescent Detection: Add LumiGLO® reagent and capture the emitted light on X-ray film.
Product Description
Background
Chemiluminescence systems have emerged as the best all-around method for western blot detection. They eliminate the hazards associated with radioactive materials and toxic chromogenic substrates. The speed and sensitivity of these methods are unequalled by traditional alternatives, and because results are generated on film, it is possible to record and store data permanently. Blots detected with chemiluminescent methods are easily stripped for subsequent reprobing with additional antibodies. HRP-conjugated secondary antibodies are utilized in conjunction with specific chemiluminescent substrates to generate the light signal. HRP conjugates have a very high turnover rate, yielding good sensitivity with short reaction times.
Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
