HEK293-CXCR7 Cells
General information
| Description | Disclaimer: The prices displayed for cell lines are exclusively for not-for-profit customers. If you represent a commercial entity, please contact us for alternative pricing. The HEK293-CXCR7 cell line is a stable recombinant HEK293 cell line engineered to express the CXCR7 receptor at a low level. This cell line was developed using inscreenex's landing pad technology, ensuring precise and reproducible integration of the CXCR7 gene at a specific, pre-validated genomic locus. CXCR7, also known as ACKR3, is an atypical chemokine receptor that modulates immune responses and tumor biology. Unlike classical GPCRs, CXCR7 does not signal through G proteins; instead, it scavenges chemokines like CXCL12 and CXCL11 and forms heterodimers with CXCR4, contributing to tumor growth, metastasis, and poor prognosis in various cancers, including breast, lung, and prostate cancers. The expression of CXCR7 in this cell line was confirmed using flow cytometry with a target-specific antibody, ensuring reliable expression across the cell population. However, the receptor density was not quantified in this cell line. |

| Subculturing | For routine adherent cell culture: Aspirate the old culture medium from the adherent cells, and wash them with PBS to remove any remaining medium. After aspirating the PBS, add the appropriate volume of Trypsin/EDTA solution based on the culture vessel size (e.g., 1 ml for a T25 flask, 3 ml for a T75 flask) and incubate at room temperature or 37?C until the cells detach (5-10 minutes). Monitor detachment under a microscope, and gently tap the vessel if necessary to release the cells. Once detached, add complete medium to inactivate the Trypsin/EDTA, gently resuspend the cells, and transfer an aliquot of the cell suspension into a new culture vessel containing fresh medium. Place the vessel in an incubator set to 37?C with 5% CO2, and change the medium every 2-3 days. |
| Split ratio | A ratio of 1:2 is recommended for the initial split after thawing. A ratio of 1:5 to 1:10 is recommended for routine culture. |
| Fluid renewal | 2 to 3 times per week |
| Freeze medium | As a cryopreservation medium, use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress. |
Quality Control & Molecular Analysis
| Sterility | Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods. To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections. |
