| Gene ID |
145957 |
| Accession | Q8WWG1 |
| Alternative Name | Pro-neuregulin-4, membrane-bound isoform, Pro-NRG4, NRG4 <br/>Recombinant Human Neuregulin-4 (NRG4) |
| Species | Human |
| Source | E. coli |
| Description | Neuregulins (NDF, heregulin, GGF ARIA, or SMDF) are EGF-like growth and differentiation factors that signal through tyrosine kinase receptors of the ErbB family. The ErbB2 and ErbB4 receptors cooperate in transmission of neuregulin-1 signals in the heart, whereas ErbB2 and ErbB3 cooperate in neural crest cells. |
| Accession | Q8WWG1 |
| Functions | The ED(50) was determined by the dose-dependent proliferation of Raji cells and was found to be <0.05ng/mL. |
| Formulation | Lyophilized from a 0.2 ?m filtered PBS, pH 7.4 solution. |
| Solubility | A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers. |
| Appearance | Lyophilized Powder |
| Molecular Weight | 7 |
| Purity | >95% as determined by SDS-PAGE |
| Concentration | <1.0 EU/μg of recombinant protein as determined by the LAL method |
| Shipping Condition | Ambient Temperature |
| Storage Condition | The lyophilized protein is stable for at least one year from date of receipt at -70?C. Upon reconstitution, this cytokine can be stored in working aliquots at 2? - 8?C for one month, or at -20?C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles. |
