100ml; sufficient for 1000cm2 membrane, 200ml; sufficient for 2000cm2 membrane


  • The most sensitive of Advansta’s HRP substrates
  • Quantitative signal
  • Also emits chemifluorescence for detection using fluorescence imagers

WesternBright Sirius is the most sensitive HRP substrate available from Advansta for chemiluminescent Western blotting. With attomole sensitivity and a long-lasting signal, WesternBright Sirius allows you to detect bands not visualized with other substrates. High signal-to-noise and a large dynamic range make it ideal for quantifying low-intensity bands. And, chemifluorescence emission allows WesternBright Sirius to be imaged by chemifluorescence imagers in addition to traditional CCD imagers and film.
