LIFR, also named as CD118, is a transmembrane protein belonging to type I cytokine receptor family, LIFR together with a high-affinity converter subunit, gp130, form a heterodimer complex that mediates the action of the leukemia inhibitory factor, a polyfunctional cytokine that is involved in cellular differentiation, proliferation and survival in the of a wide variety of cells in the adult and the embryo.

Characterization
Application
Cell Resuscitation
1. Prewarm culture medium (DMEM + 10% FBS + 1μg/mL puromycin)in a 37°C water bath.
2. Thaw the frozen vial in a 37°C water bath for 1-2 minutes.
3. Transfer the vial into biosafety cabinet, and wipe the surface with 70% ethanol.
4. Unscrew the top of the vial and transfer the cell suspension gently into a sterile centrifuge tube containing 9.0mL complete culture medium.
5. Spin at ~ 125 × g for 5-7 minutes at room temperature, and discard the supernatant without disturbing the pellet.
6. Resuspend cell pellet with the appropriate volume of complete medium and transfer the cell suspension into a T25 culture flask.
7. Incubate the flask at 37°C, 5% CO2 incubator.
8. Split saturated culture 1:3-1:6 every 3 days; seed out at about 1-3 × 105 cells/mL.
Cell Freezing
1. Prepare the freezing medium (70% DMEM + 20% FBS + 10% DMSO) fresh immediately before use.
2. Keep the freezing medium on ice and label cryovials.
3. Transfer cells to a sterile, conical centrifuge tube, and count the cells.
4. Centrifuge the cells at 250×g for 5 minutes at room temperature and carefully aspirate off the medium.
5. Resuspend the cells at a density of at least 3×106 cells/mL in chilled freezing medium.
6. Aliquot 1 mL of the cell suspension into each cryovial.
7. Freeze cells in the CoolCell freezing container overnight in a -80°C freezer.
8. Transfer vials to liquid nitrogen for long-term storage
