|---|---|
| Category | Recombinant Protein |
| Pack Size | 100UG |
| Description | Recombinant Human LIF Protein is expressed from HEK293 without tag.It contains Ser23-Phe202. |
| Target | LIF |
| Host | Human |
| Purity | > 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC |
| Scientific 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. |
| Molecular Mass | The protein has a predicted MW of 19.7 kDa. Due to glycosylation, the protein migrates to 40-55 kDa based on Bis-Tris PAGE result. |
| Sl Sequence | Ser23-Phe202 |
| Solubility | Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 μg or less, at 1mg/ml for 500μg or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking. |
| Appearance | Lyophilized |
| Endotoxin Levels | Less than 0.1 EU per μg by the LAL method. |
| Expression System | HEK293 |
| Gene Id | P15018-1 |
| Amino Acid Sequence | Recombinant Human LIF Protein is expressed from HEK293 without tag.It contains Ser23-Phe202. |
| Storage | -20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles. |
