X-ray crystallography remains the method of choice to obtain high-precision structural information about biological macromolecules. However, the protein crystallization step remains very time consuming without guarantee of success.
POLYVALAN Xo4 products are unique lanthanide complexes that act as strong nucleating agents providing new crystallization conditions and generally leading to the formation of bigger derived crystals, ready-to-use for X-ray diffraction. Xo4 are therefore providing a clear-cut solution for crystallography as they are fully compatible with developed large instruments.
