WesternBright ECL kit contains 200ml; sufficient for 2000cm2 membrane. Stronger signal than Amersham ECL or Pierce ECL. Detect low pg protein amounts. Use up to ten-times less antibody. WesternBright ECL is a horseradish peroxidase substrate optimized for chemiluminescent Western blots imaged using X-ray film. WesternBright ECL requires as little as ten times less antibody than other substrates, allowing you to save precious antibodies and samples. Additionally, the WesternBright ECL signal is long lasting, allowing multiple exposures to be carried out without substantial signal decay.
