Guava Technologies, Inc. have introduced two new turnkey assays for their suite of personal cell analysis systems.

The Guava CellToxicity Assay enables researchers to improve the performance and sensitivity of their cytotoxicity assays with a simple, non-radioactive assay that is as easy to use as population-based methods, but has superior sensitivity, specificity and reproducibility. The Guava CellPaint Assay offers single cell analysis capabilities for mixed cell cultures without the complexity of traditional methods.

The new Guava CellToxicity assay provides sensitive, single-cell analysis that is highly reproducible, minimises assay development time, and is ideal for effector cell assays: cell-mediated cytotoxicity (CMC), antibody-dependent cell mediated cytotoxicity (ADCC) and natural killer cytotoxicity (NK). The assays use a well-characterised cell tracking dye that is optimised for use on the Guava PCA systems. This dye diffuses freely into cells and is retained within the cell without affecting cellular function. Because the assay is more sensitive, specific and reproducible than population-based tests, assay development time is reduced compared to traditional methods. The Guava CellToxicity assay provides all relevant statistics, including percentage of cells killed, as well as effector and target cell percentages.

Guava's CellPaint Assay allows users to conduct mixed culture assays with the sensitivity of single-cell based methods and the throughput and ease of use of a microplate reader. Using the same fluorescent dye employed by the CellToxicity Assay or user-defined dual colour options, users can easily differentiate cell populations more easily than traditional methods. The result is greatly reduced assay development time and increased laboratory productivity.

Guava Technologies, Inc., a privately held biotechnology and medical device company, is a leading provider of on-demand, easy-to-use cell analysis systems. The Guava Personal Cell Analysis (PCA) systems, including the Guava PCA, Guava PCA-96 and Guava EasyCyte, are integrated, fully optimised, micro-capillary cytometry systems with embedded absolute cell counting capability. Used worldwide by the life science, biotechnology, pharmaceutical industries and clinical testing institutions, Guava's products have broad applications in scientific research and throughout the drug discovery and lead optimisation process, as well as for cell counting, cell health profiling, and the optimisation of commercial bio-pharmaceutical production. Guava's technology also offers potential for use in clinical testing, clinical trials and blood safety testing, as well as other areas where single cell counting and analysis is important. The Guava PCA systems are flexible, highly affordable and ultra-compact, requiring only a few microlitres of sample volume, thus saving precious and expensive cells, reagents and compounds. Guava offers a variety of assays and dedicated software modules for the Guava PCA systems, enhancing the system's overall ease-of-use.
