Simple Plex™ Assays for Viral Titer Quantification

Fast and reproducible viral capsid measurement is essential for those focused on gene transfer, as part of a cell and gene therapy workflow. While traditional plate-based and dot blot assays can be useful, they are often complex, time-consuming, and non-standardized. See how Simple Plex assays on the EllaTM platform are used for viral titer quantification. Next, meet Ella and request pricing. Finally, choose the Simple Plex Assay that best meets your needs.

Fast and Reproducible AAV2 Vector Titration

To meet increased throughput and safety demands, investigators are seeking more automated analytical solutions for assessment of viral vector identity, purity, and stability. The Simple Plex AAV2 assay on the Ella platform provides an accurate and efficient method for measuring the AAV2 capsid titer. The assay uses the recombinant AAV2 antibody (A20R) from industry leader PROGEN to quantify assembled AAV2 capsids.

Combining the proven specificity of PROGEN AAV2 antibodies with the convenient workflow and robustness of the Ella platform, the Simple Plex AAV2 viral titer assay:

  • Offers a broad viral detection range combined with hands-free automation to accelerate AAV2 viral capsid quantification
  • Uses factory calibrated assay cartridges, which help minimizes setup time and reduce user-dependent variability while reducing the need for sample retests
  • Relies on the innovative Ella platform to perform every step of the immunoassay automatically, from wash steps to final
  • Provides a robust alternative to the conventional ELISA or dot blot approaches
  • Delivers superior assay sensitivity, helping to ensure data quality and consistency

Creating Lentiviral Vectors With Fast, Reliable Viral Titration

With the growing use of lentiviral vectors derived from HIV-1 in gene transfer workflows, researchers need fast, reliable viral titer quantification during process development. The 3-to-6-hour timeframe required to run a standard ELISA is a challenge for operators who increasingly require results quickly to inform real-time decision making.

The Simple Plex assay for the detection of human HIV-1 Gag p24 combines high throughput with superior accuracy and precision to enable rapid quantification of lentiviral capsid proteins throughout different stages of cell and vector manufacturing. The automated, reproducible nature of the Simple Plex p24 assay helps eliminate user error, making it an ideal tool in good manufacturing practice (GMP) environments where quality, standardization of process, assay transfer, and scalability are highly desirable.
