Relevance

Factor that induces terminal differentiation of late-developing B-cells to immunoglobulin secreting cells.

Endotoxin

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

Purity

>98% 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 0.1 ng/ml, corresponding to a specific activity of > 1.0 x 107 IU/mg.

Form

Lyophilized powder

Buffer

Lyophilized from a 0.2 µm filtered 20mM PB, pH 7.5, 3 % trehalose, 0.1 % Tween-80

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.

Function

Factor that induces terminal differentiation of late-developing B-cells to immunoglobulin secreting cells.

Molecular Weight

13.3 kDa

Storage Conditions

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
