The Summary Table will provide a matrix of all the key features of each instrument. Click on the nickname link of a specific instrument to get a more detailed layout.  Tabs are also at the bottom listing the machine nicknames. It is essential for planning your experiments and seeing if an instrument can detect your specific markers. Please contact us if you have any questions or are in need of a specific filter set or setup for your experiments. 

Availability: 24 hours, 7 days a week.

Self Analysis on the FACSCalibur

The BD FACSCalibur is a flow cytometer analyzer equipped with 2 lasers, generating data of up to 6 parameters for each event passing through the interrogation point.

Analysis occurs at the cuvette flow cell, increasing sensitivity and resolution, allowing detection of 2 relative physical properties as well as up to 4 different colors simultaneously. It can be run at 3 different sample flow rates and is capable of analysis rates of up to 20,000 events per second.  It is operated using CellQuest Pro Software and is available for all labs to use.

 

 


Self Analysis on the LSRII / Fortessa / X20

The BD LSRII, Fortessa, and X-20 class of instruments are flow cytometer analyzers equipped with 4 or more lasers, generating data of up to 20 parameters for each event passing through the interrogation point.

The LSRII, Fortessa, and X-20 appear different, but the operation and workflow are performed in the same manner on all instrument types.  Some are also equipped to take the High Throughput Sampler (HTS) for 96 and even 384 well type plates.  Analysis occurs at the cuvette flow cell, increasing sensitivity and resolution, allowing detection of 2 relative physical properties as well as up to 18 different colors simultaneously. It can be run at 3 different sample flow rates with a fine-tune adjustor and is capable of analysis rates of up to 40,000 events per second.  They are all operated using FACSDiva Software and are available for all labs to use.

 High-throughput sampler (HTS) is available in some of these instruments, and the Core provides a logistical training to help you run it.

 

 


Self Analysis on the FACSymphony

The BD LSRFortessa X-50 (also known as FACSymphony) is the flow cytometer analyzer equipped with 4, generating data of up to 30 parameters for each event passing through the interrogation point.

Self Analysis on the Nanosight NS300

nanosightMalvern's NanoSight NS300 detects particles from 10nm to 2000nm in size, counts and sizes small particles to define concentration in solution.

  • Detects particles from 10nm to 2000nm in size
  • Configurable with lasers: 488 nm or 532 nm, AND 500LP and 532LP

Common applications of the Nanosight include:

  • Exosomes, microvesicles and extracellular vesicles characterization.
  • Viral vaccine research and development.
  • Development of drug delivery systems.
  • Protein aggregation studies.
  • Nanotoxicology.
  • Be able to analyze samples based on size distribution and concentration of all types of Nano particles from 10nm to 2000nm in diameter in solution. It is operated using the Nanoparticle Tracking Analysis (NTA) software. Sample temperature is fully programmable by NTA.
