| Catalog Number | orb426883 |
|---|---|
| Category | Proteins |
| Description | Recombinant of LIF protein |
| Form/Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Purity | Greater than 96.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
| Solubility (25°C) | It is recommended to reconstitute the lyophilized Leukemia Inhibitory Factor (LIF) in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |

| Biological Activity | The activity of rat LIF is determined by the ability to induce differentiation of M1 myeloid leukemic cells. The minimum detectable concentration of rat LIF in this assay is 0.5ng/mL. |
| Storage | Stability: Lyophilized Leukemia Inhibitory Factor (LIF) although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Leukemia Inhibitory Factor (LIF) should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles |
| Buffer/Preservatives | LIF Rat was lyophilized from 0.2µm filtered concentrated solution in 1xPBS, pH 7.4. |
