| Product Name | Recombinant Human Growth Hormone Receptor (GHR/GHBP), Partial, Biotinylated, Active |
| Catalog No. | PTR-HMM-0210 |
| Description | A biotinylated recombinant human GHR extracellular region spanning residues 27-264, produced in mammalian cells with a C-terminal mFc-Avi tag. Growth hormone-binding activity was verified by functional ELISA. |
| Intended Use | Suitable for functional ELISA, biotin-based binding assays, and growth hormone-receptor interaction studies. |
| Principle / Technology | A defined recombinant protein region is expressed and purified, then its structural quality and biological function are evaluated using the listed biochemical binding or activity assays. |
| Detection Method | SDS-PAGE; functional ELISA; LAL assay |
| Sample Type | Purified recombinant protein |
| Performance Range / Specifications | Purity: >=95% as determined by SDS-PAGE. Molecular weight: 56.6 kDa. Package sizes: 10 ug; 20 ug; 50 ug; 100 ug; 200 ug; 500 ug; 1 mg. |
| Sensitivity / LOD | In a functional ELISA, immobilized human growth hormone at 2 ug/mL bound biotinylated human GHR with an EC50 of 2.067-3.208 ng/mL. |
| Specificity | Binding activity was demonstrated with human growth hormone. |
| Reaction Conditions / Protocol | In a functional ELISA, immobilized human growth hormone at 2 ug/mL bound biotinylated human GHR with an EC50 of 2.067-3.208 ng/mL. |
