| Source | Human NF-1, amino acid (Gln32-Pro1991) (Accession: # BC117176) with a C-terminal 8His-GGQ tag was expressed in 293E cells. |
|---|---|
| Molecular Mass | The 1973 amino acid recombinant protein has a predicted molecular mass of approximately 217 kD. The DTT-reduced and non-reduced protein migrates at approximately 180 – 220 kD by SDS-PAGE. The predicted N-terminal amino acid is Gln. |
| N-terminalSequence Analysis | Gln-Pro-Ala-Pro-Val-Val-Asp-Leu-Arg-Pro |
| Purity | ≥ 95%, as determined by Coomassie stained SDS-PAGE |
| Formulation | 0.1 µm filtered protein solution is in PBS, pH 7.2. |
| Endotoxin Level | Less than or equal to 0.1 EU per μg protein as determined by the LAL method. |
| Residual Host Cell Protein Content | ≤ 0.500 ng/μg by ELISA |
| Concentration | 0.5 mg/mL |
| Storage & Handling | Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% endotoxin-free BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week or stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles. |
Unless otherwise stated, the minimum order amount is USD 1,000.
For orders below USD 1,000, an additional handling fee may apply, or we may arrange local delivery / local handover where available.

| Application Notes | BioLegend carrier-free recombinant proteins provided in liquid format are shipped on blue ice. Our comparison testing data indicates that when handled and stored as recommended, the liquid format has equal or better stability and shelf-life compared to commercially available lyophilized proteins after reconstitution. Our liquid proteins are verified in-house to maintain activity after shipping on blue ice and are backed by our 100% satisfaction guarantee. If you have any concerns, contact us at [email protected]. |

| Structure | Monomer |
|---|
| Distribution | Plasma FN (soluble dimeric form) is secreted by hepatocytes. Cellular FN (dimeric or cross-linked multimeric forms), made by fibroblasts, epithelial, and other cell types, is deposited as fibrils in the extracellular matrix. |
|---|
| Function | Fibronectins bind cell surfaces and various compounds including collagen, fibrin, heparin, DNA, and actin |
|---|
| Interaction | Cell surface, collagen, fibrin, heparin, DNA, and actin |
|---|
| Ligand/Receptor | Integrins α5β1, α4β1, α4β7, α9β1, αvβ3; non-integrin receptors TLR-4, CD44, Syndecan-4, collagen, fibrin, heparin, DNA, and actin |
