15N, heavy-labeled ubiquitin provides a stable standard for ubiquitin structural study by NMR. The recombinant human ubiquitin is purified from E. coli expressing the human ubiquitin gene. The cells are grown in media where the sole nitrogen source is 15N labeled ammonium sulfate. The recombinant human ubiquitin is purified without heating by a proprietary procedure that preserves the native structure of the protein. The purified protein is homogenous when analyzed by overloaded SDS gels. The pools of purified protein solution are extensively dialyzed against water and lyophilized.

Topiramate D12 (McN 4853 D12) is a deuterium labeled Topiramate, functioning as a broad-spectrum antiepileptic agent and GluR5 receptor antagonist. Its antiepileptic effects are achieved by enhancing GABAergic activity, inhibiting kainate/AMPA receptors, inhibiting voltage-sensitive sodium and calcium channels, increasing potassium conductance, and inhibiting carbonic anhydrase. This compound is intended for research and analytical applications.

• Can be used as a tracer.
• Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
• Enhances GABAergic activity.
• Inhibits kainate/AMPA receptors.
• Inhibits voltage-sensitive sodium and calcium channels.
• Increases potassium conductance.
• Inhibits carbonic anhydrase.
