Key facts about L929 cells
| 說明 | L-929 cells are a fibroblast-like cell line derived from the subcutaneous connective tissue of a 100-day-old male C3H/An mouse. Established in the 1940s, this cell line has become pivotal in various biological and medical research fields due to its robustness, ease of culture, and versatility in applications. L-929 cells are characterized by their spindle-shaped, fibroblastic morphology, and adherent growth. They are widely used in cytotoxicity assays and serve as a standard model to assess the biocompatibility of materials and the toxic effects of various substances, which is particularly relevant in the fields of biomaterials and tissue engineering. L-929 cells are also employed in the study of cytokine activity, especially in assays for necrosis factor (TNF) activity, due to their sensitivity to TNF-induced cytotoxicity. This makes them valuable in immunology and inflammation research. L-929 cells are further utilized in virology as a host for viral replication studies. Their susceptibility to various viruses, such as the infectious bursal disease virus (IBDV), facilitates the investigation of viral life cycles, host-virus interactions, and the efficacy of antiviral compounds. Overall, the L-929 cell line is a valuable resource in scientific research and offers a versatile platform for studies in cytotoxicity, immunology, virology, and biomaterials. |

| 營養補充品 | Supplement the medium with 10% FBS |
| 解離試劑 | Accutase |
| 倍增時間 | 25 hours |
| 傳代培養 | 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. |
| 播種密度 | 2 to 3 x 104 cells/cm2 |
| 流體更新 | 2 to 3 times per week |
| 解凍後的恢復 | 24 to 48 hours |
| 冷凍培養基 | 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. |
| 細胞解凍與培養 |
|
| 培養環境 | 37°C, 5% CO2, humidified atmosphere. |
| 運送條款 | 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. |
| 儲存條件 | 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
| 不孕症 | 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. |
