| Short Description : | This NRG4 Sandwich ELISA is an in-vitro enzyme-linked immunosorbent assay for the measurement of samples in human serum, plasma and other biological fluids. |
| Storage Instruction: | If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual. |
| Assay Time: | 3.5h |
| Detection: | Colormetric |
| Gene Symbol: | NRG4 |
| Gene ID: | 145957 |
| Uniprot ID: | NRG4_HUMAN |
| Specificity: | This kit recognizes Human NRG-4 in samples. No significant cross-reactivity or interference between Human NRG-4 and analogues was observed. |
| Sample Type: | Serum, plasma and other biological fluids |
| Function | Low affinity ligand for the ERBB4 tyrosine kinase receptor. Concomitantly recruits ERBB1 and ERBB2 coreceptors, resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors. Does not bind to the ERBB1, ERBB2 and ERBB3 receptors. |
