Recombinant Human Noggin Protein, His Tag
Product No.: PRP1942
Product Overview
This product is a high‑purity recombinant human Noggin protein produced using an Escherichia coli expression system. A C‑terminal His tag facilitates detection and purification. The protein specifically binds and neutralizes members of the transforming growth factor‑β (TGF‑β) superfamily, particularly bone morphogenetic proteins (BMPs), and is valuable for studies of cell differentiation and embryonic development.
Key Features
- High purity: SDS‑PAGE analysis indicates purity > 98%
- Low endotoxin: LAL assay < 0.1 EU/µg
- Bioactivity confirmed: Inhibits BMP4‑induced alkaline phosphatase activity in ATDC5 cells, ED₅₀ = 1.22 ng/mL
- Defined structure: Composed of 206 amino acids, predicted molecular weight 23.2 kDa
Product Information
| Expression host | Escherichia coli |
| Protein sequence | Human Noggin (UniProt: Q13253, Gln28‑Cys232) |
| Tag | C‑terminal His tag |
| Form | Lyophilized powder; buffer: 20 mM Tris, 50 mM NaCl, pH 8.0 |
Suggested Applications
- Stem‑cell differentiation studies
- BMP signaling pathway modulation assays
- Bone and cartilage formation mechanism research
- Neurodevelopment and joint‑formation model systems
Usage Instructions
Reconstitute with the supplied Reconstitution Buffer to a concentration of at least 102 µg/mL. The solution can be further diluted as required for experiments. Reconstituted material is stable at 4 °C for short‑term storage (2–7 days). For long‑term storage, keep at ≤ ‑20 °C and add 0.1 % HSA or BSA as a stabilizer; avoid repeated freeze‑thaw cycles.
Storage and Shipping
- Storage condition: Dry environment at ≤ ‑20 °C
- Shipping condition: Dry ice shipment
