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

Lyophilized powder.

Lyophilized from a 0.2 μm solution of 50 mM Tris-HCL, 300 mM NaCl, pH 7.4.

<1 EU/μg, determined by LAL method.

The specifaction of 2/10/50/100 µg is recommended to reconstitute to a concentration of 200/200/1000/1000 μg/mL in sterilized water respectively. For concentration less than that, please reconstitute in 50 mM Tris-HCL, 300 mM NaCl, pH 7.4 buffer.

Stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
