This product is a CHO-K1 stable cell line that stably expresses human GPR1 receptor. Upon agonist binding to GPR1, β-arrestin is recruited to the activated receptor, bringing together the split luciferase fragments and generating luminescent signal after substrate addition. Therefore, receptor activity can be easily quantified in live cells in a dose-response manner by measuring changes in luminescence levels. This cell line is suitable for high-throughput screening (HTS) and receptor β-arrestin functional evaluation assays.

Figure 1. Dose Response of Recombinant Human Chemerin in GPR1 β-Arrestin CHO(C13)
The dose-response curve shows β-arrestin recruitment induced by recombinant human Chemerin. The EC₅₀ value is 20.2 ng/mL, measured via luminescence signal (RLU).
Cell Resuscitation
1)Rapidly thaw the frozen cells in a 37 °C water bath for approximately 60 seconds. Once thawed (which may take slightly less or more than 60 seconds), immediately transfer the cell suspension from the cryovial into a 15 mL centrifuge tube containing 10 mL of pre-warmed CHO-K1 Human GPR1 β-Arrestin Cell Line complete culture medium.
2)Centrifuge cells at 1000 rpm for 5 min to remove medium, then resuspend cells in 5 mL of pre-warmed complete medium.
3)Transfer the cell suspension into a T25 culture flask and incubate at 37 °C with 5% CO₂.
4)After approximately 24–36 hours, replace the medium or passage the cells to remove non-adherent dead cells.
Subculturing procedure
1)When the cell density reaches the appropriate confluency for passaging, wash the cells with PBS, then add 1 mL trypsin to detach the cells. When more than 80% of the cells detach upon gently tapping the culture flask, add complete culture medium to terminate digestion. Gently pipette to obtain a single-cell suspension, transfer to a 15 mL centrifuge tube, and centrifuge at 1000 rpm for 5 minutes.
2)Discard supernatant after centrifugation. Resuspend cells in fresh medium to a single-cell suspension and transfer to a new culture flask for continued growth.
Cell Freezing
After trypsinization and centrifugation of cells from each T75 flask or 10 cm culture dish, discard the supernatant. Add 2 mL of cryopreservation medium (90% FBS + 10% DMSO), gently resuspend thoroughly, and aliquot into two cryovials. Immediately place the cryovials into a controlled-rate freezing container (e.g., Nalgene 5100-0001), fill with isopropanol to the indicated level, and store at −80 °C. After 24 hours, transfer the cryovials to liquid nitrogen for long-term storage.
