Quick SDSPAGE analysis: Prelabel protein samples with ready to use Cy5 dye for quick, sensitive detection without gel staining and destaining Easy Western blot normalization: Use standard 30 min protocol for quantitative Western blotting results; avoids the need for loading controls Wide sample range: Effectively label complex samples or pure proteins from 1 µg/mL to 20 mg/mL, so no need to premeasure protein concentrations Good sensitivity: As sensitive as silver staining with wider dynamic range Broad dynamic range: Simultaneously detect main band and impurity levels as low as 0.1% intensity of main band, using a fluorescence scanner or imager Versatility: Load samples onto selfpoured gels or a variety of commercial gels; possible because most materials have low Cy5 fluorescence
