What is the purpose of using a high viscous injector?
The high viscous injector allows for the characterization of protein crystals embedded in viscous materials, improving data collection.
How are bubbles removed from the syringe?
Bubbles are removed by applying gentle pressure to create a seal and then quickly releasing the pressure to burst any bubbles.
What materials are used in this protocol?
Glass syringes and a high viscous medium are primarily used for sample preparation.
What is the significance of minimizing sample waste?
Minimizing sample waste is crucial for efficient use of materials and for maximizing the amount of usable data collected.
Can this method be used for other soft materials?
Yes, this method is designed to characterize various soft materials that are difficult to analyze with traditional setups.
