Protein crystallization tips and tricks - analysis using polarizers with the UVXPO 'MRC' 2-drop plate
|
The new UVXPO 'MRC' 2 drop plate from Swissci offers advances in UV and cross-polarized imaging.
The new plate has exactly the same dimensions as the original MRC 2-drop crystallization plate,
but is made from a special polymer that is designed to maximize UV and polarized light.
Key features of the UVXPO 'MRC' 2-drop plate:
- Uniform background when using polarized light.
- UV imager compatible.
- More hydrophilic surface than the original MRC 2 drop UV plate (COC) gives better dispensing.
- OryxNano, Oryx4 and Oryx8 can dispense screening and optimization experiments.
- Oryx8 can dispense reservoir solutions for optimization.
- Oryx LCP systems can dispense LCP experiments to the plate.
The UVXPO 2-drop plate is available from Douglas Instruments.
Tips and tricks for using the UVXPO plate:
Although the UVXPO MRC plate has a very low uniform birefringence, when the plate is sealed, often the seal does have birefringence and acts a wave plate.
This means one is unable to get a true black or white background as the polarizer is rotated with a normal plate seal.
To cancel out the waveplate effect, simply add a second layer of the same plate seal exactly
perpendicular to the first.
