- Very easy to use
- Spray-and-go or mix by pipetting
- Optimised signal strength for detections in upper femtogram range
- Well suited for medium- and long-term exposition
- Suitable for NC membranes, optimised for PVDF membranes
Efficient Western-Blot substrate based on luminol, for chemoluminescent detection of horseradish peroxidase (HRP) on membranes. Through an optimised composition, high signal strength is achieved over a very stable plateau of over 30 mins.
By using pump spray bottles no time-consuming pre-mixing of solutions is required - substrate solution 1 and enhancer solution 2 are simply sprayed onto the membranes. Hereby, the spray technique guarantees a very smooth and regular distribution of the substrate on the membrane surface, hence avoiding artefacts caused by uneven distribution of pipetted substrate. Through the high signal strength, proteins in the upper femtogram range may be detected, while concentrations of the antibodies used may be reduced.
- Spray the membrane with solution 1
- Afterwards spray membrane with solution 2
- Incubate approx. 1 min (wrap membrane in saran foil etc.)
ROTI®Lumin is transformed by the HRP into an excited dianion in the presence of hydrogen peroxide. When the dianion is reversed back to its normal state, light is emitted. The light emission of ROTI®Lumin reaches its maximum within 5 minutes and remains at the maximum level for approx. 1-2 hours.
ROTI®Lumin plus ready-to-use, for protein and cytoimmunochemistry
For a mini blot of 7 × 8 cm size 3-4 pump strokes are necessary.
In case passed down protocols are to be used the spray-bottles may easily be unscrewed, mixing and applying the solutions by pipetting.
For medium or long-term exposure we recommend use of Roti®-Lumin plus.
