Overview
This product is a stable CRISPR knockout cell line in which CCR3 has been disrupted in the (Human (H. sapiens)) background using CRISPR-Cas9 genome editing. It provides an isogenic model for loss-of-function studies of CCR3 in blood tissue context. Cells are supplied frozen (1×10⁶ cells / 1.0 ml, BSL-II) and grow as suspension, lymphoblast monolayers.
CRISPR Knockout Design
- Target gene: CCR3
- Knockout strategy: CRISPR-Cas9–mediated frameshift-inducing INDEL generation; confirmed by sanger sequencing of frameshift-inducing indels
- Design notes: The CCR3 CRISPR Knockout Jurkat Cell Line is a specialized derivative of the Jurkat T lymphocyte cell line, engineered via CRISPR/Cas9 technology to lack the CCR3 gene, which encodes the chemokine rec
- Parental cell line: — Human (H. sapiens), blood origin
Gene Background
CCR3 is a protein-coding gene. Its encoded protein participates in cellular processes relevant to the biological pathways associated with blood biology. For detailed gene function, pathway context, and disease associations, refer to the NCBI Gene and UniProt entries for CCR3.

Research Applications
- Validate CCR3 knockout by Western blot or qPCR versus the isogenic parental line.
- Investigate loss-of-function phenotypes: proliferation, viability, morphology, or pathway activity changes.
- Screen drug candidates targeting pathways regulated by CCR3 using this KO as an isogenic control.
- Perform rescue experiments by re-expressing wild-type CCR3 in the knockout background.
- Conduct transcriptomic or proteomic profiling comparing KO versus parental cells.
Important Notes
- Add selection antibiotic to culture medium only after the first passage post-thaw to allow cells to recover.
- Cell viability upon thaw is warranted for 30 days following shipment when handled per abm guidelines.
- For laboratory research use only. Not intended for diagnostic, therapeutic, or clinical applications.
- Thaw cells quickly in a 37°C water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination.
- Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions.
- Transfer the cell suspension into a 15ml sterile conical tube containing 5ml of pre-warmed, complete growth media. Centrifuge cells at 125xg for 5-7 minutes.
- Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media and dispense into a T25 culture flask.
- Incubate the cells at the recommended conditions.
- Aspirate the culture media, and add 2-3ml of pre-warmed 0.25% Trypsin-EDTA to the culture vessel.
- Observe the cells under a microscope to confirm detachment (typically within 2-10 minutes). Cells that are difficult to detach can be put in 37°C, for several minutes to facilitate detachment.
- Neutralize Trypsin-EDTA by adding an equal volume of the complete growth media into the culture vessel.
- Transfer the culture suspension into a sterile centrifuge tube, and centrifuge at 125xg for 5 minutes. The actual centrifuge duration and speed may vary depending on the cell type.
- Aspirate the supernatant, and re-suspend the pellet with pre-warmed fresh complete growth media. Add appropriate aliquots of the cell suspension to new culture vessels, as desired.
- Incubate the cells at the recommended conditions.
