Luciferase reporter cell line NALM6 is engineered to express luciferase as a reporter gene, allowing for the monitoring of gene expression levels in real-time. In 1976, Minowada et al. isolated NALM-6 cells from the blood culture of a male ALL patient who was 19 years old. A model for B-cell differentiation, invasion of the central nervous system (CNS), metastasis, and precursor B-cell leukemia is NALM-6, a cell line derived from B-cell leukemia. Reporter gene experiments can be performed with NALM-6 cells that have been modified to carry the reporter gene, making them perfect for evaluating the effectiveness of new CAR-T cell treatments or other immunotherapies in vivo.
The appearance of NALM-6 cells is similar to that of lymphoblasts, with tiny, spherical, suspended cells. A near-diploid human karyotype is shown by chromosomal analysis. In immunocompromised mice, these cells grow into tumors and can spread spontaneously to the liver, spleen, lymph nodes, and bone marrow. The validity of NALM-6 cells is verified by STR profiling, and there is no evidence of mycoplasma contamination.
For NALM-6 cells, RPMI-1640 media supplemented with 10% fetal bovine serum and 37°C culture temperatures with 5% carbon dioxide are the suggested culture conditions. To maintain cell density between 1×10^5 and 2×10^6 cells/ml, it is recommended to change the culture media two to three times a week. The cells have a doubling duration of roughly 36 hours.
Innovative drug discovery methods for cancer treatment rely on identifying therapeutics that selectively eliminate diseased cells. The scientists created the "Matador-Glo assay," a novel cytotoxicity test based on Luc146-1H2, a thermostable Click Beetle Luciferase variant. To detect luminescence in this assay, Luc146-1H2 is ectopically overexpressed in the cytosol of target cells using D-luciferin as the substrate. Luc146-1H2 is either released from dead and dying cells or its activity is preferentially detected in these cells upon damage to the integrity of the cell membrane. The procedure is easy to use, quick, sensitive, precise, labor-saving, and low-cost. Furthermore, a dual luciferase assay for detecting cell death can be created by combining the Matador-Glo assay with the marine luciferase-based Matador assay. Additionally, the researchers showed how target cells expressing Luc146-1H2 might be employed for in vivo bioluminescence imaging.

1. Gene Expression Monitoring: The luciferase reporter cell line NALM6 makes it possible to track the expression levels of genes in real time, which is helpful for a variety of research applications, including assessing the effectiveness of novel immunotherapies or CAR-T cell treatments.
2. Leukemia Study Model: NALM-6 is a model for B-cell differentiation, invasion of the central nervous system, metastasis, and precursor B-cell leukemia that is derived from B-cell leukemia.
3. Research on Tumor Growth and Metastasis: NALM-6 cells can be used to research tumor growth and metastasis since they spontaneously spread to critical organs such as the liver, spleen, lymph nodes, and bone marrow after being implanted in immunocompromised mice.
Customer Q&As
Luciferase Reporter Cell Line - What is the Luciferase expression level of the NALM6 cell line? Is it stable under different culture conditions?
A: Our Luciferase Reporter Cell Line - NALM6 has undergone rigorous screening and verification to ensure stable expression of the Luciferase gene. Through methods such as luciferase activity detection and PCR, we verified the expression level of Luciferase and performed repeated tests at different time points and in different batches. Cells can maintain stable Luciferase expression under appropriate culture conditions and are suitable for long-term experimental use.
What impact does NALM6 background have on the performance of this Luciferase cell line? Are there any special training requirements?
A: As a human acute lymphoblastic leukemia cell line, the background of the NALM6 cell line may affect the proliferation and response characteristics of the cells, but it will not significantly affect the expression of Luciferase. We recommend that customers pay attention to the special growth requirements of the NALM6 cell line during use, such as culture medium components and culture conditions. Detailed culture guidelines will help customers maintain their cells in optimal condition.
Have the cell lines for this product been tested for contaminants? How to ensure the purity of cell lines?
A: Yes, our Luciferase Reporter Cell Line - NALM6 has undergone rigorous contaminant testing, including testing for common contaminants such as mycoplasma and bacteria. We use methods such as PCR and cell culture testing to ensure the purity of our cell lines. We have strict quality control procedures to ensure that each batch of cell lines meets high standards of purity.

Experimental results are good
When working with the Luciferase reporter cell line NALM6, I noticed some nice properties. The cells grow uniformly, gene expression is stable, and the performance is quite reliable. The appearance of NALM6 cells is similar to lymphoblastoid cells, showing a tiny, spherical, and suspended form. They form tumors in immunodeficient mice and can spread spontaneously to the liver, spleen, lymph nodes, and bone marrow. STR typing verified the validity of NALM6 cells and there was no evidence of mycoplasma contamination.
