What Is Titration

Written by Tim Bushnell, PhD Titration is the process of identifying the best concentration to use an antibody for a given assay. While the vendor will provide a specific concentration to use, this may not be appropriate for your assay....

Differential Pressure

Written by Tim Bushnell, PhD Differential pressure based flow cytometers currently dominate the market. These systems have two pressure regulators. The first is at a constant pressure that sets how fast the fluids runs at. The second is regulated by...

5 Keys To Writing A Shared Instrument Grant

Written by Tim Bushnell, PhD I'm a scientist, not Perry Mason. I’m not a defense attorney or a detective. Why would I say that? Because well before March grant writers need to be a Perry Mason – make the case...

How To Train Your Personnel

Written by Tim Bushnell, PhD ExCyte chooses to train people in flow cytometry because we know what it's like to feel the pain of ruined experiments. No one enjoys wasting thousands of dollars on reagents and priceless amounts of instrument...

The Importance Of Teaching With Integrity And Passion

Written by Tim Bushnell, PhD Flow cytometry education has grown phenomenally in response to more sophisticated instrumentation, growing demands for more sensitive, high-speed and multi-parameter flow. Specialized training is critical to any flow lab competing in today's global marketplace. The...

The Jablonski Diagram

Written by Tim Bushnell, PhD A Jablonski diagram illustrates the electronic states of a molecule as well as the transitions between them. These states are arranged vertically by energy and grouped horizontally by spin multiplicity. Nonradiative transitions are indicated by...
