Lentiviral Vector/Transgene/Biomarker Protein Biodistribution Analysis

Lentiviral vectors can confer high levels of gene transfer and transgene expression in a variety of cell types. However, the biodistribution and toxicity after intravenous administration have not been reported. RNA ISH and IHC allow analysis of vector DNA, transgene mRNA, and biomarker protein, respectively, while preserving the cellular relationship and tissue architecture. Researchers have found that combining or multiplexing both technologies provides unique information. Lentiviral Vector/transgene/Biomarker Protein Biodistribution Analysis from Creative Bioarray combines RNA in situ hybridization (RNA ISH) and Immunohistochemistry (IHC) can help validate and accelerate your gene therapy development.

RNA ISH and Immunohistochemistry (IHC) combination presents several significant advantages when used in lentiviral vector gene therapy, including the following:

  • High-resolution Visualization: RNA ISH allows for the direct observation and localization of specific lentiviral vector, transgene, or biomarker RNAs within the spatial context of cells or tissues at high resolution.
  • Quantitative Analysis: RNA ISH and IHC combination permits a quantitative analysis of the lentiviral transduction efficiency, transgene expression, and biomarker RNA biodistribution in targeted cells or tissues.
  • Co-expression Study: The integration of these two methods provides a comprehensive analysis of the co-expression of the transgene and a particular cellular marker, providing insights into the molecular and cellular effects of the gene therapy.
  • Compatibility with Archival Samples: The techniques can be performed on well-preserved, formalin-fixed, and paraffin-embedded tissue sections, making them compatible with the analysis of archival samples.
  • Single-cell Studies: RNA ISH offers single-cell level insights which could provide information for the better understanding of cellular responses towards lentivirus-driven gene therapies.

Therefore, the combination of RNA ISH and IHC stands as a powerful tool for the evaluation of the safety, efficacy, and mechanisms of lentiviral vector-based gene therapy. Another advantage of the techniques is that they are broadly applicable to investigate the distribution and behavior of other viral vectors and genetically engineered cells in gene and cell therapies.
