WesternBright Sirius is the most sensitive chemiluminescent HRP substrate offered by Advansta, specially engineered to produce an extremely strong signal to detect low-abundance proteins and to work with very low antibody concentrations. The substrate also produces a strong chemifluorescent signal that can be detected with fluorescence imagers.

• Detect Low-Abundance Proteins
• Low Background for High Signal-to-Noise Ratio
• Long-Lasting Signal for Flexible Imaging
• Image Chemiluminescence by CCD or Film, Image Chemifluorescence with laser-based Fluorescence with Laser-Based Fluorescence Imaging Systems

WesternBright Sirius is the most sensitive HRP substrate available from Advansta for chemiluminescent Western blotting. With attomolar 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 fluorescence imagers in addition to traditional CCD imagers and film.
