Protein G, Staphylococcus aureus (His)

Measured by its binding ability in a functional ELISA. Immobilized Protein G at 2μg/mL (100μL/well) can bind Biotinylated Human IgG1. The ED₅₀ for this effect is 0.1099 μg/mL.

Approximately 27 kDa

• 
  Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized a 0.2 μm filtered solution of PBS, pH 7.4, 5 % trehalose, 5 % mannitol and 0.01% Tween80.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
