LICOR IRDye Streptavidin, 800CW Series, 0.5mg, 1mg/mL, Liq; LIC-926-32230

LI-COR IRDye Streptavidin, 800CW Series, 0.5 mg Net Content, 1 mg/mL, Liquid Form, Green, 4 deg C. IRDye 800CW streptavidin is supplied as a liquid in buffer containing 10 mM phosphate, 183 mM NaCl, 2.7 nM KCl, pH 7.4 with sodium azide 0.005% (w/v) as a preservative. To use, centrifuge briefly before use to eliminate aggregates that may have formed in solution. This will reduce non-specific background staining. A final concentration of 0.2 to 1 ug/mL (1:1000 to 1:5000) is usually satisfactory for most applications; however, appropriate dilution may need to be determined empirically. For membrane-based applications and in-gel westerns, it is recommended to add SDS (0.02% to 0.1% final concentration), in addition to Tween 20 (0.1 to 0.2% final concentration) during the detection incubation step to reduce non-specific background staining (Additional S&H or Hazmat Fees May Apply) - LIC
