TERM2, full named as Triggering receptor expressed on myeloid cells 2, is a membrane protein which expressed primarily in immune cells across many different tissues, and form a receptor signaling complex with TYROBP, also named as DAP12, then mediates signaling and cell activation after binding serval ligands, it plays an important role in different inflammatory diseases, especially Alzheimer's disease, and is also believed as a promising target for cancer therapy.

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
