Never Email FCS Files Again!

Are you working with a collaborator who needs to see your raw data? Are you looking for help from a Cytobank administrator relating to experiment analysis?

Don’t bother opening your email client, searching for an email address, and digging through folders for your flow files. Instead, use the easy sharing features built into Cytobank. Once you have uploaded files to your account, they can be easily shared with others from within the Cytobank interface.

As always, your experiment is visible only to you until you actively choose to give permission to another user to see it. When you do choose to share an experiment, follow these easy steps:

Working with Accuri Data

Cytobank users have uploaded and analyzed data collected from more than 30 different flow cytometer models, so chances are that Cytobank can handle your data! In a recent post, we featured the ability of Cytobank to facilitate the mining of data from large datasets generated by the DVS Sciences CyTOF. This time, we will walk you through analysis of data collected on the Accuri cytometers using their CFlow software.

Image plots from Accuri CFlow

Accuri provided us with a set of sample files demonstrating the collection of data from cells stained with a PE-anti-CD4 antibody, and we’ll use this as an example. You can see from their CFlow software analysis that they achieve separation of and gate on the lymphocyte population (P1, first panel), and further separate CD4+ from CD4- cells (second two panels). We’ll show you how to do the same in Cytobank!

What is SPADE?

What is SPADE?

SPADE (Spanning-tree Progression Analysis of Density-normalized Events) is a way to automatically identify populations in multidimensional flow cytometry data files. SPADE clusters cells into populations and then projects them into a tree like the one shown below. SPADE works for data from both ‘classic’ fluorescence flow cytometry and mass cytometry.

A New Way to Publish Data: Cytobank Reports

We’re excited to announce Cytobank Reports, a new feature on Cytobank that will soon enable users to “publish” their data and findings. We’re also excited to announce that the first Cytobank Report (available here) features the mass cytometry study published today in Science, reporting on the simultaneous measurement of 34 parameters in single hematopoietic cells.

Also, more details to come, but stay tuned for a new resource from BD Biosciences powered by Cytobank Reports.

Mass Cytometry: Vaporizing Cells in the Name of Science

Mass cytometry, a technique developed by DVS Sciences, now a Fluidigm Company represents a revolutionary spin on classic fluorescence-based flow cytometry. Instead of using antibodies tagged with fluorophores (in which spectral overlap quickly limits the number of parameters available for simultaneous detection), mass cytometry relies on antibodies tagged with transition element isotopes. Antibody-bound cells are vaporized, ionized, and analyzed on a mass spectrometer.

Teaching Phospho-Flow… in France

Dataset #5002: Timecourse LACI 2011

This January, Jonathan and Chris from Cytobank traveled to Marseilles, France to help lead a course as part of the Luminy Advanced Course in Immunology (LACI). LACI is organized as a satellite meeting to the Immunology and Metabolism meeting and organized by the Centre d’Immunlogie de Marseille-Luminy (CIML) and the European Molecular Biology Organization (EMBO).

The ‘Cell Signaling’ course at LACI was taught by local instructors Nathalie Auphan-Anezin and Pierre Grenot, both of CIML, and Jonathan and Chris. The course led course participants through staining, collection, upload, and analysis of a phospho-flow experiment. We’ve briefly described the experiment here, made a version of the dataset public along with the original course protocol, and prepared a tutorial (part 1 and part 2) to lead you through Cytobank analysis of the course data.
