YEASEN ECL series luminescence Kit is designed to detect antibodies and associated antigens directly or indirectly labeled with horseradish peroxidase (HRP). The principle is that proteins or nucleic acids were transferred to the imprinted membrane after electrophoresis, and the target proteins on the membrane were bound by primary antibody and secondary antibody labeled with HRP, or the nucleic acids on the membrane were bound directly or indirectly by probes labeled with HRP. After washing the membrane, the ECL working solution prepared by the product was used to incubate the membrane at room temperature for several minutes. The imprinted membrane was wrapped with plastic wrap and fixed to the X-ray exposure Cassette. Then the X-ray film is pressed on the membrane in a darkroom and exposed for several seconds to several hours. After development and fixing, protein or nucleic acid bands can be clearly displayed on the X-ray film.
This kit has a unique luminescent/enhanced substrate system, and Western blotting detection of medium fick-grade can be achieved. In addition to X-ray, can also be detected by fluorescent CCD.


  • High sensitivity and high signal-to-noise ratio, it can detect medium fick-grade antigens.
  • The signal lasts for 24 hours, and the luminescence time is more than 10 times longer than that of conventional ECL substrate. High-quality imprinted images can be obtained by multiple exposures for publication.
  • Higher dilution ratio of antibodies can be used to greatly save antibodies.
  • Dilution ratio of primary antibody (liquid storage concentration 1mg/ mL) : 1:1000-1:50000.
  • Dilution ratio of secondary antibody (liquid storage concentration 1mg/ mL): 1:50000-1:250000.

  • Western Blot 
  • Dot Blot-DNA/RNA 
  • Southern blot-DNA
