Union Biometrica, Inc. to exhibit at the International Society for Stem Cell Research (ISSCR) 12th Annual Meeting in Vancouver, BC, Canada

The BioSorter flow cytometer is designed to provide the flexibility for working with samples ranging in sizes from 1 to 1500 microns.  These samples can be analyzed and dispensed intact owing to the low sample pressures, low shear forces and the gentle sorting mechanism. Union Biometrica has developed an autosampler, LP Sampler, that automatically loads samples from multiwell plates to the BioSorter for analysis and resorting.  


We invite you to learn more about our technologies by joining us for the following Innovation Showcase:

Title: Large particle flow cytometry provides high throughput analysis and automation for cell clusters (EBs, spheroids) and encapsulated 3D cell cultures.

Topic: Embryonic stem cells (embryoid bodies), neural stem cells (neurospheres), certain solid tumors (tumorspheres) and other cell types all tend to form cell clusters. These clusters are a more natural arrangement, where cell-cell interactions and cell-substrate contacts can be established and maintained. Union Biometrica discusses the use of their Large Particle Flow Cytometers for automating the multiparametric analysis and gentle intact dispensing of these types of cell clusters to wells of multi-well plates.

Presenter: Rock Pulak, Ph.D.

Details: Thursday, June 19, 8:00am – 8:30am, West Meeting Room 211-214


About Union Biometrica, Inc.

Large Particle Flow Cytometry for Gentle Sorting -- Union Biometrica offers tools for high throughput research of stem cells and cell clusters (iPS cells and embryoid bodies as well as other types of large cells / cell clusters), bead based assays, plus model organisms (early stages of zebrafish, C.elegans, Drosophila embryos and larvae, sea urchin embryos, Xenopus eggs and embryos, Daphnia, various marine larvae and zooplankton). We provide 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. These systems analyze and sort objects based on size and fluorescent parameters. Automating this process offers increased speed, sensitivity, quantification, and repeatability of experiments. 

For examples of Stem Cell and Cell Cluster screens - including hiPS and embryoid bodies as well as other types of large cells / cell clusters including adipocytes, neurospheres, duct cells and pancreatic islets – please see:
