Recombinant Human LIF Protein
产品特性
| Synonyms: | Leukemia Inhibitory Factor; LIF; Differentiation-Stimulating Factor; D Factor; Melanoma-Derived LPL Inhibitor; MLPLI; Emfilermin; LIF; HILDA |
| Product Description: | Recombinant Human Leukemia Inhibitory Factor is produced by our E.coli expression system and the target gene encoding Ser23-Phe202 is expressed. |
| UniProt ID: | P15018 |
| Species: | Human |
| Expression System: | E.coli |
| Tag: | Tag free |
| Predicted MW: | 19.7 KDa |
| SDS-PAGE: | 18 KDa, reducing conditions |
| Formulation: | Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. |
| Endotoxin Level: | Less than 0.001 ng/µg (0.01 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 25-150 pg/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
LIF has the capacity to induce terminal differentiation in leukemic cells. Its activities include the induction of hematopoietic differentiation in normal and myeloid leukemia cells, the induction of neuronal cell differentiation, and the stimulation of acute-phase protein synthesis in hepatocytes.
