uPAR Protein, Human (HEK293, His)

1.Lyophilized from a 0.22 μm filtered solution of 20 mM Tris-HCl, 10% trehalose, 2% mannitol, 0.05% Tween 80, pH 8.0.
2.Lyophilized from a 0.22 μm filtered solution of 20 mM Tris-HCl, 8% trehaolse, 2% Dextran-70, 50 mM NaCl, 0.05% Tween 80, pH 8.5.
3.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4, 8% trehalose.
Please refer to the lot-specific COA for specific buffer information.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

<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 from date of receipt. 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.
