Union Biometrica, Inc. to exhibit at the Western New York Flow Users Group Meeting in Rochester, NY on July 18, 2012.

We invite you to the following presentation by Dr. Rock Pulak: 
Large particle flow cytometry for large delicate cells and cell clusters. 
Flow cytometry provides for multiparametric analysis of single cells in suspension. However not all cells are amenable to study in flow with conventional single cell flow cytometers. Certain cells are too large to pass through the analysis chamber or they are too delicate to withstand the shear forces experienced on these instruments. Also, there is a growing realization in today’s research that studying pure populations of individual cells of one type does not address all the important biological questions. There is a developing understanding for a need to study interacting cells in cell clusters, tissues, and organs with an appreciation that cells communicate with each other, respond to cues from other cells and their surrounding environment. Understanding these interactions will be of critical importance to the successful development of the new therapies. This is true for research areas such as regenerative medicine, stem cell biology and solid tumor cancers.
COPAS and Biosorter flow cytometers (Union Biometrica, Inc.) are able to analyze and dispense large biological particles such as large delicate single cells (hepatocytes, adipocytes, plant protoplasts) and cell clusters (porcine pancreatic islets, mouse embryoid bodies, tumor spheroids) and hydrogel microcarriers. The low pressures and gentle sorting mechanism result in minimal affect on viability and normal physiological response of the biological samples. Applications of this technology will be presented.

About Union Biometrica, Inc.
Union Biometrica designs and markets Large Particle Flow Cytometers (COPAS™ and BioSorter®) for objects that are too large / too fragile for traditional cytometers and offer an alternative to manual sorting under a microscope. These systems sort and dispense objects based on size and fluorescent parameters. Automating this process offers increased speed, sensitivity, quantification, and repeatability of experiments. 
Peer reviewed journal papers referencing the sorting of cell and cell clusters using our COPAS™ and BioSorter® instruments can be viewed using the links below.
