Description
It is supplied in a 1.5 ml microtube (conical bottom and a screw cap for inserts with O-Ring). Each microtube contains 0.6 mg of Terbium macrocyclic complex Tb-Xo4. Crystallophore No 1(Tb-Xo4) - is a unique, patented chemical tool for protein crystallography developed by Polyvalan, Lyon, France. It is a luminescent Terbium complex that is an effective nucleant and provides significant isomorphous and anomalous phasing power.
Tb-Xo4 is a rapid, easy-to-use tool that presents multiple advantages:
- It is soluble and stable in all crystallisation conditions and consequently fully compatible with high throughput screening.
- It acts as a strong Nucleating Agent providing new crystallisation conditions and generally leading to the formation of bigger, Tb-Xo4 derivatised crystals, ready-to-use for X-ray diffraction.
- Under UV irradiation, the complex emits in the green (Luminescent) enabling very easy detection of the Tb-Xo4 derivatised crystal in crystallization drops.
- The crystallophore is a straightforward Phasing Agent facilitating crystal structure determination using SAD or MAD methods, due to the exceptional anomalous properties of f-block elements.
