EF1a-hHOXA9(RFP, Bla) Lentiviral Particles

EF1a-hHOXA9 (RFP, Bla) lentiviral particles are cutting-edge tools in gene manipulation and cell engineering. These particles are designed to deliver the human HOXA9 gene under the efficient control of the EF1a promoter, ensuring stable and sustained expression in a variety of mammalian cell types. This lentiviral vector system offers numerous advantages, including high transduction efficiency, stable genome integration, and the ability to transduce both dividing and non-dividing cells. This makes it particularly important for primary cell lines or stem cells that are difficult to handle with other transfection methods. Furthermore, the introduction of the RFP reporter gene allows researchers to easily observe and track transduced cells using fluorescence microscopy or flow cytometry, enabling real-time monitoring of transduction efficiency and transgene expression. The blast fungicide resistance gene provides a powerful screening mechanism, allowing researchers to enrich successfully transduced cells and maintain stable cell populations under antibiotic stress. This dual-selection system improves experimental reliability by minimizing background noise from untransduced cells.

The primary application of EF1a-hHOXA9 (RFP, Bla) lentiviral particles is in cell immortalization. HOXA9 is a homeobox transcription factor whose overexpression induces durable proliferative capacity in normally senescent primary cells. This is particularly useful for establishing continuous cell lines from limited patient-derived samples, such as hematopoietic stem cells, fibroblasts, or epithelial cells, which can serve as a renewable resource for long-term research. In cancer research, immortalized cell lines expressing HOXA9 can be used to study oncogenic pathways, drug resistance mechanisms, and tumor microenvironment interactions. The RFP reporter gene further supports its application in cell migration assays, co-culture systems, and in vivo tracking in xenograft models. Beyond immortalization, these particles also play a crucial role in functional genomics research, exploring the role of HOXA9 in development, differentiation, and disease pathogenesis, including its significance in leukemia and solid tumors.
