Crystallophore No 1 (large vial , 0.6mg) MD2-80
Crystallophore No1 acts as a nucleating agent and improves crystal quality of pre-existing hits. As shown right for T5 phage with and without Crystallophore No1 (top right).
Crystallophore No1 luminesces strongly in the visible region under UV excitation making detecting crystals in drops and loops easy. See middle right.
Terbium is a lanthanide and therefore has significant potential for use as an anomalous scatterer and in traditional isomorphous replacement. When Crystallophore No1 has been used as a nucleant, it is often found bound to the protein thus providing high quality phasing power.

(bottom right) P. horikoshii Protease 1 electron density from SAD phasing using the Terbium LIII absorption edge. Crystal grown in 10 mM and subsequently soaked in 100 mM crystallophore No1.
Each large vial ccontains 0.6 mg of the complex, enough to set up 10 96-well plates of your target protein in complex with 10 mM Crystallophore No1 (recommended concentration). Shipped at room temperature. The dry powder will keep for upto 1 year in a sealed tube at room temperature in dry conditions. Solutions of Crystallophore No1 can be kept for up to 2 months in a sealed tube. Solutions of the compound mixed with your target protein should be used immediately.
