Product Description |
Recombinant Human LIF Protein is expressed from HEK293 with hFc tag at the C-Terminus.It contains Ser23-Phe202. |
Product Background |
Leukemia inhibitory factor (LIF) has played a vital role in a series of reproductive events, including follicle growth, embryo growth and differentiation. However, it is unclear whether the level of LIF in embryo culture medium can be used as a marker for clinical pregnancy. |

HEK293 |
Purity |
> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC |
Endotoxin |
Less than 1EU per ug by the LAL method. |
Form |
Lyophilized |
Shipping |
Shipped at ambient temperature. |
Formulation |
Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Stability And Storage |
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. |
