Product news

Guava Technologies, Inc., a leading developer of cost-effective and accessible cell-analysis systems, brings the power of flow cytometry directly to Immunology researchers with compact, easy-to-use cytometry systems.

Incorporating patented microcapillary technology, Guava Personal Cell Analysis systems are a fraction of the size of traditional sheath flow systems but provide comparable results for almost all cytometry experiments.

Guava Technologies' systems, including the Guava PCA, PCA-96, EasyCyte and EasyCyte Mini, are affordable, highly compact, microlitre-scaled cell analysis systems that offer integrated, turnkey operations. Only a few microlitres of samples are required for each experiment, saving precious cells and reagents and producing up to 100x less biohazardous waste than traditional flow systems. All Guava systems sample precisely measured volumes of fluid, meaning that all of Guava's turnkey assays provide accurate cell counts without the use of reference beads. These highly sensitive systems offer precise, accurate and easy-to-read results with often less than one day of training. Whether you are looking to count T cells, measure proliferation or quantify cell death, Guava's absolute counting will drastically simplify the process.

All of Guava's turnkey assays come with optimised reagents and specialised user-friendly software. From a mix-and-read annexin V apoptosis assay to a non-radioactive cytotoxicity assessment, Guava systems and assays have been used for applications including eliminating variability in Elispot assays, Hybridoma screening, ADCC screening, Apoptosis studies, Immunophenotyping, CD4 T cell counting, Leukocyte reduction, Cell cycle analysis and NK Effector analysis.

Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays. Find the best flow cytometers, cell counters and cell sorters in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.Cell-Based AssaysCell-based assays are used to monitor the presence, quantity and activities of a desired cellular analyte including drug molecules or biomarkers. This can reveal information on cell health (apoptosis, cytotoxicity, viability and proliferation assays), cell metabolism, cell migration and cell signaling mechanisms.
