PD-L1 CRISPR Stable Knockout MC38 Cell Line

T61491x106 cells / 1.0 ml



PD-L1 CRISPR Stable Knockout MC38 Cell line is derived from a widely used murine colon carcinoma model, MC38. Guide RNAs (gRNA) carried on a gRNA cloning vector were used to target exon 1 of the mouse CD274 gene encoding Programmed death-ligand 1. Successful knockout of PD-L1 was verified by immunefluorescence after cells were subjected in interferon-gamma. Programmed death-ligand 1 (PD-L1) is known to be frequently expressed on both tumor cells and tumor-infiltrating immune cells and is implicated in the suppression of immune response via the induction of T-cell exhaustion. This line may be valuable for use in drug screen studies or in the investigation of PD-L1 related signaling and function.

Propagation Requirements
Use of PriCoatTM T25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) is required for cell adhesion to the culture vessels. Grow cells in ECM-coated culture vessels unless otherwise specified in the Propagation Requirements below.

The base medium for this cell line is Prigrow V medium available at abm, Cat. No. TM015. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (TM999)* to a final concentration of 8%, Penicillin/Streptomycin Solution (G255) to a final concentration of 1%, and L-glutamine (G275) to a final concentration of 2 mM.
Change media every 2-3 days.
Carbon dioxide (CO2): 5%, Temperature: 37.0°C.
* Do not use heat-inactivated FBS for cell culture unless specified otherwise.

2. Sale of this item is subjected to the completion of a Material Transfer Agreement (MTA) by the purchasing individual/institution for each order. If you have any questions regarding this, please contact us at [email protected].

3. All test parameters provided in the CoA are conducted using abm's standardized culture system and procedures. The stated values may vary under the end-user's culture conditions. Please verify that the product is suitable for your studies by referencing published papers or ordering RNA (0.5 μg, Cat.# C207, $450.00) or cell lysate (100 μg, Cat.# C206, $600.00) to perform preliminary experiments, or alternatively use our Gene Expression Assay Service (Cat# C138). All sales are final.

4. We recommend live cell shipments for ease of cell transfer and this option can be requested at the time of ordering. Please note that the end-user will need to evaluate the feasibility of live cell shipment by taking into account the final destination's temperature variation and its geographical location. In addition, we thoroughly test our cell lines for freeze-thaw recovery. If frozen cells were received and not recovered in your lab under the exact, specified conditions (using recommended culture vessel, media, additional supplements, and atmospheric conditions), a live cell replacement is possible at a cost (plus shipping).
