IGR-1 Cells
CAD$545.10*
Products are shipped frozen on dry ice in cryotubes. Each cryotube typically contains 3 × 106 cells for adherent lines or 5 × 106 cells for suspension lines (refer to the batch CoA for details).
General information
| Description | The IGR-1 cell line is derived from a human malignant melanoma, making it a valuable model for studying the pathophysiology of melanoma and testing anti-cancer therapies. These cells are epithelial in nature and exhibit characteristics typical of aggressive melanoma, including rapid proliferation and the ability to form colonies in soft agar, a hallmark of oncogenic transformation. The IGR-1 cell line is particularly useful in research focused on understanding the molecular mechanisms driving melanoma progression, as well as in the development and testing of targeted therapies and immunotherapies. IGR-1 cells harbor mutations common in melanoma, including alterations in the MAPK/ERK pathway, which is often dysregulated in this cancer type. These mutations contribute to the cell line's ability to proliferate uncontrollably and resist apoptosis. Researchers utilize IGR-1 cells to investigate the effects of various inhibitors on this signaling pathway, providing insights into potential therapeutic strategies. Additionally, the cell line's expression of melanoma-associated antigens makes it suitable for studying immune responses against melanoma, including the development of novel immunotherapeutic approaches. |

Handling
| Culture Medium | DMEM, w: 4.5 g/L Glucose, w: 4 mM L-Glutamine, w: 3.7 g/L NaHCO3, w: 1.0 mM Sodium pyruvate (Cytion article number 820300a) |
|---|---|
| Supplements | Supplement the medium with 10% FBS |
| Dissociation Reagent | Accutase |
| Subculturing | Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium. |
| Seeding density | 3 x 104/cm2 after thawing, 1 to 2 x 104/cm2 for routine splitting |
| Fluid renewal | 2 to 3 times per week |
| Post-Thaw Recovery | 1 to 2 days |
| Freeze medium | As a cryopreservation medium, we 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. |
| Thawing and Culturing Cells |
|
| Incubation Atmosphere | 37°C, 5% CO2, humidified atmosphere. |
| Shipping Conditions | Cryopreserved cell lines are shipped on dry ice in validated, insulated packaging with sufficient refrigerant to maintain approximately −78 °C throughout transit. On receipt, inspect the container immediately and transfer vials without delay to appropriate storage. |
| Storage Conditions | For long-term preservation, place vials in vapor-phase liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable only as a short interim step before transfer to liquid nitrogen. |
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. |
