Relevance

Cytokine secreted predominantly by activated T-lymphocytes as well as mast cells and osteoblastic cells that controls the production and differentiation of hematopoietic progenitor cells into lineage-restricted cells.

Endotoxin

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

Purity

Greater than 95% as determined by SDS-PAGE.

Activity

Yes

Bioactivity

The ED50 as determined by the dose-dependent stimulation of the proliferation of TF-1 cells is 0.3149 to 1.023 ng/mL.

Form

Lyophilized powder

Buffer

Lyophilized from a 0.2 μm filtered PBS, 6% Trehalose, pH 7.4

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.

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.
