Simple Plex Solutions For Cell Therapy Manufacturing

The manufacturing of gene-modified immune cells is a multistep process that requires rigorous product characterization at various points throughout the workflow. Ella gives you the critical information you need faster, with superior sensitivity and reproducibility that supports regulatory compliance. Accelerate your process development with automated Simple Plex assays for viral titer, process impurity testing, and T cell characterization.


Simple Plex Viral Titer Assays

Accurate detection and quantitative measurement of viral titer in cell cultures is critical for implementation of effective gene transfer treatment strategies. Simple Plex assays are available to quantify viral titers of both lentivirus and adeno-associated virus capsids.

The HIV p24 antigen is a commonly used Lentivirus protein used in cell therapy applications. It is imperative that researchers have an assay they can trust. The Simple Plex HIV p24 assay offers ultra-wide dynamic range and consistent, precise results in less than 90 minutes.

Partnering with PROGEN, the industry leader in AAV antibodies and quantification, the Simple Plex AAV assays offer hands-free automation, a 3.6 log dynamic range and highly precise and reproducible data. Simple Plex AAV assays are available for AAV1, AAV2, AAV6, and AAV8.

Simple Plex Process Impurity Assays

To bring you the best quality immunoassays, we’ve partnered with the industry leader in bioprocess impurity testing-- Cygnus Technologies.

The Simple Plex HEK 293 HCP 3G Assay

The Simple Plex HEK 293 HCP 3G (SPCKB-OT-007066) assay on Ella offers broad detection coverage of the most relevant host cell proteins (HCPs). Ella delivers excellent sensitivity and extended dynamic range to ensure precise sample detectability at each stage of the purification process. The assay is based on the same antibodies currently used in the Cygnus HEK 293 HCP ELISA kit, 3G Resupply 1 (F650S). As a result, you get the same accuracy and consistency you would expect from the Cygnus ELISA, but with an automated, streamlined workflow. The Simple Plex HEK 293 HCP 3G assay is available for purchase directly from Cygnus Technologies.

How Does the Simple Plex HEK 293 HCP 3G Assay Compare with the Cygnus ELISA?

In this application note, we demonstrate assay comparability between the Simple Plex HEK 293 HCP 3G assay and the Cygnus HEK 293 HCP ELISA 3G Resupply 1 ELISA to show that you get the same high-quality data you would expect from the Cygnus ELISA with an automated, streamlined workflow.

Endonuclease App Note

The Simple Plex Endonuclease Assay

Endonuclease is a non-specific nuclease that degrades DNA and RNA by breaking phosphodiester bonds without any proteolytic activity. Its applications include host cell nucleic acid digestion in viral vector preparation, vaccine, and biotherapeutic development. Residual endonuclease must be cleared from the final product to avoid downstream adverse effects. Download this application note to learn about the Simple Plex Endonuclease assay.

Multianalyte Measurements For Immune Cell Characterization

Multianalyte cartridges on Ella allow you to take multiple biomarker measurements in parallel rather than in multiplex. This ensures the highest quality data since all assays are run in a discrete environment. Combine any four analytes from our menu into a custom panel for your immune cells.
