Product details:
Ultra High Sensitivity ECL Substrate Kit ab133409 is a horseradish peroxidase (HRP) substrate specially developed for Western blotting detection of very low abundance proteins with 1.2pg-2ng of protein per band. ECL Substrate Kit ab133409 produces a strong, long-lived signal, which, combined with very low background levels, allows for long exposure times enabling the detection of low-abundance proteins. Additionally, the signal from ECL Substrate Kit ab133409 is linear with respect to protein amount over a broad range of concentrations, allowing the user to accurately quantify protein bands.
ECL Substrate Kit ab133409 is most suitable for detection of low-abundance proteins or in situations when amounts of available primary antibodies are very limited and high dilution factors are desired, or when primary antibodies have relatively low binding constants.
This ECL Substrate Kit also compatible with X-ray film detection, though the limited dynamic range of film will make resulting data less quantitative. The ECL substrate also produces a chemifluorescent signal that can be detected with a fluorescence imaging system using appropriate excitation and emission settings.
Our ECL kits include our popular ECL Substrate Kit
ab65623
and our high sensitivity ECL substrate kits:
- High Sensitivity ECL Substrate Kit
ab133406
to detect 23pg-187ng of protein per band
- Very High Sensitivity ECL Substrate Kit
ab133408
to detect 4.6pg-4.7ng of protein per band
- this kit (Ultra High Sensitivity ECL Substrate Kit ab133409) to detect 1.2pg-2ng of protein per band
Detection ranges in pg and ng stated above should be used for guidance only as detection range is dependent on the molecular weight of a protein.
This product was previously called Optiblot ECL Ultra Detect Kit (1.2pg-2ng).

The primary antibody can often be diluted 5 to 10 fold more than usual when using this ECL substrate. A typical primary antibody dilution range using the substrate is 1/5000 - 1/20,000, with a typical secondary antibody dilution range of 1/20,000 - 1/100,000. Some optimisation may be required.
