  Less than 1.0 EU/μg as determined by LAL method.

• Purity:

  >97% as determined by SDS-PAGE.

• Activity:

  Yes

• Bioactivity:

  Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using human TF-1 cells is less than 0.5 ng/ml, corresponding to a specific activity of > 2.0 x 106 IU/mg.

• Form:

  Lyophilized powder

• Buffer:

  Lyophilized from a 0.2 µm filtered PBS, pH 7.2, with 5 % trehalose

• Reconstitution:

  We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
