Tag Info
Tag-Free
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Form
Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer
Lyophilized from a 0.2 μm sterile 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 Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Lead Time
3-7 business days
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
Shelf Life
The shelf life is related to many factors, storage state, storage temperature and the stability of the product itself. Generally, the shelf life of lyophilized form is 6 months at -20°C/-80°C from the date of receipt.

Activity
The ED50 as determined by the dose-dependent stimulation of the proliferation of NIH-3T3 cells is 0.9252-2.630 ng/mL.
Description
FGF2 orchestrates cell proliferation, survival, and angiogenesis by binding heparan sulfate proteoglycans and activating FGFR tyrosine kinase signaling, making it a central regulator in wound healing, neural development, and tumor vascularization. This tag-free bovine FGF2, spanning the complete mature protein (aa 10–155), demonstrates dose-dependent mitogenic activity on NIH-3T3 fibroblasts with an ED50 of 0.9252–2.630 ng/mL, confirming receptor-binding potency suitable for cell proliferation assays, stem cell maintenance protocols, and angiogenesis models. Expressed in E. coli to yield an unglycosylated form that retains full biological function, the protein aligns with standards expected in receptor-ligand binding studies, including surface plasmon resonance and competitive ELISA formats. Purity exceeding 95% by SDS-PAGE and endotoxin below 1.0 EU/μg meet the quality thresholds commonly required for in vitro differentiation experiments and antibody validation workflows.
