产品特性
| Synonyms: | Interleukin-5; IL-5; B-cell differentiation factor I; Eosinophil differentiation factor; T-cell replacing factor; TRF; IL5 |
| Product Description: | Recombinant Human Interleukin-5 is produced by our Mammalian expression system and the target gene encoding Ile20-Ser134 is expressed with a 6His tag at the C-terminus. |
| UniProt ID: | P05113 |
| Species: | Human |
| Expression System: | Human Cells |
| Tag: | C-6His |
| Predicted MW: | 14.2 KDa |
| SDS-PAGE: | 20 KDa, reducing conditions |
| Formulation: | Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. |
| Endotoxin Level: | Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test. |
| Activity: | Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells. The ED50 for this effect is 0.1-0.5 ng/ml. |
| Purity: | >95% |
| Reconstitution: | Always centrifuge tubes before opening.Do not mix by vortex or pipetting. |
| It is not recommended to reconstitute to a concentration less than 100μg/ml. | |
| Dissolve the lyophilized protein in distilled water. | |
| Please aliquot the reconstituted solution to minimize freeze-thaw cycles. | |
| Stability and Storage: | Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. |
| Reconstituted protein solution can be stored at 4-7°C for 2-7 days. | |
| Aliquots of reconstituted samples are stable at < -20°C for 3 months. |

产品背景
Homodimeric cytokine expressed predominantly by T-lymphocytes and NK cells that plays an important role in the survival, differentiation, and chemotaxis of eosinophils (PubMed:2653458, PubMed:9010276).
Acts also on activated and resting B-cells to induce immunoglobulin production, growth, and differentiation (By similarity).
Mechanistically, exerts its biological effects through a receptor composed of IL5RA subunit and the cytokine receptor common subunit beta/CSF2RB (PubMed:1495999, PubMed:22528658).
Binding to the receptor leads to activation of various kinases including LYN, SYK and JAK2 and thereby propagates signals through the RAS-MAPK and JAK-STAT5 pathways respectively (PubMed:7613138).
