Alexa Fluor 488, F(ab’)2 fragment of Goat anti-rabbit IgG(H+L) (min. X Hu, Ms)
Fluorescence microscopy: 1-2 ug/mL
Alexa Fluor dyes are superior to Cy dyes for antibody labeling by having combined advantages in brightness, photostability, specificity and novel features ideal for in vivo imaging.
|Buffer:||pH~7.4 PBS containing 50 mg/mL glycerol 2 mg/mL BSA (IgG-free and protease-free) and 0.0.5% sodium azide.|
|Storage:||Store at 4°C for several months. Protect from light. For longer storage, divide the conjugate into small aliquots and freeze at -20°C. Avoid repeated freezing and thawing.|
|Properties:||Color and Form: yellow solution. Spectral Property: λAbs/λEm = 490/515 nm (in pH 7.4 PBS buffer) Alexa Fluor 488 is spectrally similar to DyLight 488 Cy2 and FITC.|
