LICOR IRDye 680LT Streptavidin (0.5 mg)

Supplier:  LICOR 92668031

IRDye 680LT 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 1.0 µg/ml (1:1,000 to 1:5,000) 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.
