Overview
The GFP Control C4-2 Cell Line, transduced with Lenti-CMV-CBH-GFP-2A-Puro-Blank vector, is a vital tool for cancer research, especially in studies focused on prostate cancer. This cell line is derived from the C4-2 prostate cancer cell line, which itself is a subline of the LNCaP cells known for their androgen sensitivity and ability to form osteoblastic lesions, mimicking advanced prostate cancer.
Key elements and design rationale
- Model identity: GFP Expressing C4-2 Stable Cell Line is supplied as a tumor cell line derived from Human prostate.
- Growth properties: Adherent, epithelial-like
- Growth conditions: PriCoat™ T25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) are recommended for optimal cell culture. RPMI 1640 Medium (TM503) + 10% FBS(Regular*) + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂. 1.0 µg/ml Puromycin (G264) for selection. Note: Selection drugs should be added to the culture medium after the first passage to ensure cells have recovered from freeze-thaw conditions. *Do not heat-inactivate
- Engineering / immortalization: Gfp reporter expression.
- Product format: Frozen, BSL-2
This cell-based model is generally used in cancer biology, phenotype comparison, and response profiling studies.
Biological background
The introduction of the Lenti-CMV-CBH-GFP-2A-Puro-Blank vector serves multiple purposes. Green Fluorescent Protein (GFP) under the control of the CMV (Cytomegalovirus) promoter allows for easy visualization and tracking of the cells under fluorescent microscopy. This feature is invaluable for in vitro experiments focusing on cell proliferation, migration, and drug response, as well as for in vivo studies where tracking the localization and metastatic spread of prostate cancer cells is crucial.Inclusion of a puromycin resistance gene (Puro) enables the selection of successfully transduced cells, ensuring a population of cells uniformly expressing GFP. This selective pressure is essential for maintaining a stable cell line over prolonged experiments.Overall, this cell line is a usefule control in experiments to establish the baseline behviour of prostate cancer cells without specific modifications.
Research relevance and current trends
- Cell-line models continue to be used for tumor phenotype comparison, pathway perturbation studies, and assay development in controlled in vitro systems.
- Engineered and subtype-defined tumor lines are often used to compare growth behavior, reporter output, and response patterns across matched experimental conditions.
- When metastatic or lineage features are described, investigators commonly interpret results alongside morphology, passage history, and culture environment.
Common research applications
- Cancer biology studies that compare proliferation-associated behavior, morphology, and pathway responses in vitro.
- Assay development for treatment response, reporter monitoring, or phenotype comparison under matched culture conditions.
- Side-by-side comparison of engineered versus parental background characteristics when relevant to the study design.
Changes in morphology, growth rate, viability, or reporter signal are typically interpreted together with passage history, culture matrix, and the specified growth conditions for the model.
Notes for experimental interpretation
- Morphology, doubling behavior, and reporter or marker output can shift with passage number, substrate choice, and medium composition; these variables should be recorded alongside experimental readouts.
- Matched controls such as parental cells, untreated cultures, or parallel cultures maintained under identical conditions help distinguish background effects from biology of interest.
Culture and product details
- Growth Conditions: PriCoat™ T25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) are recommended for optimal cell culture. RPMI 1640 Medium (TM503) + 10% FBS(Regular*) + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂. 1.0 µg/ml Puromycin (G264) for selection. Note: Selection drugs should be added to the culture medium after the first passage to ensure cells have recovered from freeze-thaw conditions. *Do not heat-inactivate
- Split Ratio: 1:2 or 1:3
- Population Doubling Time (h): 24-48
- 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.

How many times can cells divide?
Primary cells have a limited lifespan and will undergo a finite number of population doublings before entering senescence. The exact number varies by cell type and culture conditions.
Immortalized cell lines are capable of extended or indefinite proliferation under proper culture conditions, although growth characteristics may vary between lines.
Do I need Applied Cell Extracellular Matrix (G422) if I am using PriCoat™ flasks?
