MA900 Multi-Application Cell Sorter


Sorting that adapts to your needs with default and custom sort modes as well as 4-way sorting

Once events are gated on plots, target cells can be sorted for further analysis. Sort mode, sort gates, and sort devices can be assigned using a simple dialog box. A choice of eight default and five custom sort modes is available to achieve the desired purity and yield of the sorted population. Sort devices supported include 2-way and 4-way tubes as well as 6-, 12-, 24-, 48-, 96-, and 384-well plates.

Experiment Settings

Experiments can be created by selecting a new template, a recent experiment, or a shared template (public) from the experiment window. If a new template is selected, the software guides you through choosing experiment settings such as sample groups, tubes, and pulse parameters for data acquisition. Once a template is selected or created, compensation data can be acquired easily by using the software based compensation wizard. Alternatively, uncompensated populations can be adjusted using the drag and drop feature in the software.

Data Display and Using Gates

During acquisition, data is displayed on worksheets as dot plots and histograms. Events in the plots can be marked using gates. A variety of tools are provided to select, adjust, label, and measure statistics of target populations. Once acquired, data can be easily exported as FCS formats to use with third party analysis software.

Automated Sort Monitoring

The software monitors and actively makes adjustments to the drop drive to maintain a stable breakoff point. This feature ensures consistently good sort performance, facilitates walk-away operation, and allows detection of clogs and empty tubes.


Sort Deposition System

The Sort Deposition System is an optional hardware feature that facilitates high-throughput sorting and precise deposition of cells into 6-, 12-, 24-, 48-, 96-, and 384-well plates or PCR plates. Several features on the MA900 enable deposition of single cells at a high efficiency. These include the ability to precisely adjust the position of a plate, assign the center of the drop relative to the target cell position, and utilize custom angled plate holders for multiwell PCR and 384-well plates.

Index Sorting Software

Index sorting software records the X and Y coordinates of each event sorted into a multiwell device. This very precise and easy to use software brings powerful capabilities to research, enabling you to track the scatter and fluorescence intensity of individual cells sorted in each well.

After the sort, the index file can be exported in CSV format or analyzed on the cell sorter. The Well Select feature lets you choose a well and display event(s) sorted in that well on bivariate plots and histograms. The Gate Select feature lets you display the location of events on a plate map based on a selected gate.

These index sort options allow you to perform meta-analysis of data for several applications. For example, clonal variability can be studied based on the expression levels of the fluorescent protein or surface markers. Also, researchers can integrate phenotypic data with mRNA expression analysis of the sorted cells.
