Abnova™ Fluorescent Dye 488-I Streptavidin
Descrizione
Fluorescence Dye 488-I conjugates are significantly brighter than fluorescein conjugates and much more photostable. Additionally, the fluorescence of Fluorescence Dye 488-I is not affected by pH between 4-10. Compared to Alexa Fluor 488, Fluorescence Dye 488-I of single isomer has much higher purity, bringing better performance consistency from batch to batch. Ideal for labeling via Streptavidin for fluorescence imaging and other fluorescence-based biochemical analysis. For most fluorescent streptavidin applications, a concentration of 1 to 20g/mL is sufficient. The optimal working dilution should be determined by the end user.
