Applications

The Fluidity One-W’s unique capabilities allow you to study protein complexes and their formation in crude biological backgrounds such as cell lysates or blood plasma. Absolute size measurements of protein complexes by the Fluidity One-W helps to confirm the identity of your complex and means you can control for off-target binding and false positive measurements. Combined with minimal sample preparation and automatic KD calculation, you can confidently analyse your protein at the earliest possible stage, reducing the time for important go/no-go decisions.

How does the Fluidity One-W work?

The Fluidity One-W measures the rate of diffusion of proteins under steady state laminar flow in a microfluidic chip - a technique known as microfluidic diffusional sizing (MDS).

With Fluidity One-W

  • Assess binding in native conditions

    By measuring your proteins and their interacting partners in a close-to-native, biological background, you can expect more transferable results that accurately represent natural biological processes.

  • Study proteins in any solution

    Work in crude biological mixtures with minimal preparation, while controlling for off-target binding. Gain valuable insights at the earliest possible stage.

  • More for less

    Gain meaningful insights into protein complexes and their formation with less sample and in less time.

  • Look at the hard stuff

    Solution state measurement coupled with high sensitivity means you can study proteins that are problematic for other systems such as:
    -Membrane proteins
    -Multi protein complexes
    -Intrinsically disordered proteins

  • Avoid wasted downstream processing

    Assess the quality of your protein complex even in early stage fractions, allowing you to optimize protocols early. Use insights on protein size, state and yield to rationalize how you move forward before you begin time consuming purification.

  • Pipette, plug, play

    The minimal sample prep, easy-to-use design and wide dynamic range means you will spend less time setting up, and more time generating the data you need.
