Quantity:

50 µg

Data Sheet:

ul-613-isg15-fluorescein.pdf

ISG15 modified with fluorescein via primary amine coupling, resulting in the modification of lysine residues as well as the N-terminus. This labeled ISG15 allows for direct detection spectophotometrically with higher efficiency and sensitivity than with antibodies.

Product Information

Stock:

X mg/ml (XμM) in 50mM Hepes pH 7.5, 100mM NaCl. Actual concentration varies with lot number.

> 95% by SDS-PAGE

Use & Storage

Use:

Fluorescein-ISG15 gives a strong signal in the range of 0.1-1 μM, depending on exact experimental conditions. Optimal fluorescence at pH 8.0 is monitored using Ex₄₉₀ nm and Em₅₁₅ nm wavelengths respectively.

Storage:

Store at -80°C. Avoid multiple freeze/thaw cycles.
