Granada Crystallization Box ®FOR PROTEIN CRYSTALLIZATION Granada Crystallization Box® (GCB) is a simple device to crystallize protein and other biological macromolecules by counter-diffusion method. GCB consists of 4 elements made of polystyrene: - A reservoir to introduce the gel
 - A guide to hold capillaries
- A cover
- A holder to maintain the boxes
The GCB has been designed to be used in four different ways: - To grow crystals inside gels under diffusion controlled mass transport.
- To grow protein crystals inside capillaries with un-gelled precipitating agent by the counter-diffusion technique.
- To grow protein crystals inside capillaries with gelled precipitating agent by the counter-diffusion technique.
- To grow protein crystals inside capillaries by the batch method.
Main characteristics: - Crystallization is performed under diffusion-controlled mass transport.
The role of viscous fluids, gels and/or micro-gravity is enhanced by using capillary volumes.
- Reduces the consumption of macromolecule:
From 500 nanoliters to 100 nanoliters of protein solutions depending on the inner diameter of the capillaries.
- Automatically searches for the optimal crystallization conditions:
One capillary scans the same precipitation region than hundreds of drops.
- Easy and safe transport to x-ray diffraction facilities
Transport your precious crystals in your pocket!
- Full visualization of the crystallization process
- In situ x-ray crystallography:
Crystals grow inside x-ray capillaries If desired, no handling of crystals Usable for cryo-crystallography
Triana Science & Technology offers GCBs in packages of 20 boxes Reference | Price per package | GCB - A - 20 | 130 € |
