Preparing Stock Solutions

The following data is based on the product molecular weight 257.67. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 3.88 mL 19.4 mL 38.81 mL
5 mM 0.78 mL 3.88 mL 7.76 mL
10 mM 0.39 mL 1.94 mL 3.88 mL
50 mM 0.08 mL 0.39 mL 0.78 mL

  • Huntington's disease
Huntington's Disease

Huntington's Disease Poster

Huntington's disease (HD) is a monogenic neurodegenerative disorder, which is characterized by the prevalent loss of GABAergic medium spiny neurons (MSN) in the striatum. This poster summarizes the MSN intracellular signaling pathways implicated in the pathology of HD, as well as highlighting the use of iPSCs for HD modeling.


Schizophrenia Poster

Schizophrenia is a debilitating psychiatric disorder that affects 1% of the worldwide population. This poster describes the neurobiology of Schizophrenia, as well as highlighting the genetic and environmental factors that play a fundamental role in the etiology of the disease. The current and emerging drug targets are also discussed.
