TransPass™ V

  • Catalog # M2561 was discontinued on January 01, 2013
  • Product Information
    TransPass™ V is an Adenovirus-derived enhancer component that is used along with a transfection reagent. The combination of a TransPass transfection reagent & TransPass-V significantly enhances transfection efficiency in many cell lines and primary cells including endothelial or epithelial (1,2). For example, the combination of TransPass D2 & TransPass V yields optimal plasmid transfection efficiency in suspension cells (Figure 1). This combination has low toxicity and thus, transfected cells show very little, if any, cell death (Figure 2).

    *TransPass-V contains a replication-deficient Adenovirus preparation. Because of the nature of this component, it should not be used with cell lines that contain Adenovirus sequences such as HEK-293, to avoid complementation of the virus. Additionally, it is recommended that common laboratory biosafety used in standard Adenovirus work is practiced. For more information see

    TransPass V is a proprietary formulation manufactured by Targeting Systems. Please direct all inquirires regarding reagent composition to Targeting Systems.

    Guidelines for Endothelial Cell Culture:
    • Use early passages of cells (up to the 6th passage) for transfections.
    • Use non-collagen and non-gelatin coated tissue culture plates only (transfection of cells plated on collagen-coated surfaces may result in lower transfection efficiency).
    • Recommended media: MCDB131 from VEC technologies, Media 199 plus supplements and 20% fetal calf serum or EBM from Cambrex plus supplements and 10% fetal calf serum. Cells grown in these media appear healthier and give higher transfection efficiency.
    • Clonetics HUVEC cells have given very good transfection results.
    Transfection Guidelines:
    • For consistent results, it is important to maintain healthy proliferating cells that are regularly passaged.
    • If cells have been grown in medium containing heparin, they must be washed after trypsinizing and resuspended in growth medium without heparin and antibiotics/antimycotics before plating for transfection.
    • It is important that NO heparin and NO antibiotics/antimycotics in the growth medium during transfection.
    • Use sterile plasmid DNA purified by CsCl gradient centrifugation or column chromatography.
    • The amount of plasmid DNA per transfection can be varied, and the ratio of HUVEC Reagent Component to TransPass-V should be kept between (1:1) and (1:2).
    Figure 1:
    Transfection efficiency of TransPass reagents in Jurkat. Although Jurkat is a suspension cell line, the proliferating culture of Jurkat, was trypsinized to declump the cells. Trypsin was added to cell pellet followed by 5 minutes of incubation at 37°C, 5% CO2. The cells were washed once and resuspended in complete growth medium containing no antibiotics/antimycotics before plating at 70% cell density for transfection. Transfection was carried out for 24 hours. Supernatants were collected and assayed for Gaussia Luciferase (GLuc) activity using the Gaussia Luciferase Assay Kit (NEB #E3300).
