Specialized Western Blot Imaging System

More Applications:

Western blot as a classical protein quantification technique has been preceived as the golden standard for protein expression studies and has become an essential experiment for every molecular biology laboratory. However, the development of western blot technology has been very slow, among which the imaging detection technology has suffered from stagnant development for over 20 years.

The earliest imaging method adopted was DAB colorimetry, which had been eliminated because of its lack of sensitivity and quantitative range.

The chemiluminescence method was later emerged. There are 2 imaging methods used- darkroom filming and cold CCD imaging.

  • The darkroom filming method features a very limited quantitative range that makes accurate quantitation even impossible. Therefore it is gradually abandoned by scientists.
  • Nowadays the cold CCD imaging remains widely-used. The method replying on lens to fulfil the imaging process makes the imaging distance too long, plus the small-sized chip, thus resulting in even lower imaging sensitivity compared to darkroom filming. Its quantitative range is also too narrow to meet the increasing requirements of scientific researches.

Some people also try to use fluorescence imaging to do western imaging. Yet due to the fluorescence background interference of the film, fluorescence methods are far less sensitive than chemiluminescence methods, so they are also rarely used.

The revolutionary touch chemiluminescence imaging technology of e-Blot makes full advantage of the high sensitivity of the chemiluminescence method, overcomes many shortcomings of cold CDD imaging, and improves the imaging sensitivity, 2-3 logs higher quantitative range and efficiency, leading western imaging into a whole new era.

New technology allows you to design the experiment with confidence

Two orders of magnitude higher than cooled CCD on sensitivity

While most x-ray film and cooled CCD western blot imaging systems may skip on weaker signals on a given samples, the e-Blot Touch Imager’s sensitive imaging chips bring them all out.

Adjustable exposure level allows for stronger bands to be regulated while weaker signals are encouraged to appear for accurate data acquisition. The enhanced sensitivity also eliminates false findings that could consume more time for samples to be repeated and images recaptured.

Wide quantitative range, strong and weak signals are clearly visible

Ultra-sensitive imaging chips come with enhanced sensors that pick up even the faintest of signals in a sample that traditional x-ray film and CCD might miss and capture them all in a single image.

Signal variation is properly displayed on the image, helping scientists retrieve valuable data from even the rarest and low-abundant protein bands that will push forward research performed on the subject.

Two orders of magnitude higher than cooled CCD on quantitative range

As image capture is conducted through direct contact rather than distance capture, the dynamic range of the Touch Imager is proportionally higher than modern cooled CCD technology that the market offers.

The extended dynamic range also ensures that all details needed from the sample is recorded accurately, displaying various bends with precision accuracy.

Obtain Results Faster

95% experiments done within seconds

Thanks to the increased sensitivity and range of our Touch Imager’s photosensitive chip, 95% of the sample is captured in just 1 second.

The captured image of the sample provides accurate results based on specified details, eliminating the need to redo the experiment and significantly cutting time consumption by a great margin. Image editing and analysis are also available in the instrument for detailed images that help in better research.
