Preparing Stock Solutions

The following data is based on the product molecular weight 176.22. 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.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 5.67 mL 28.37 mL 56.75 mL
5 mM 1.13 mL 5.67 mL 11.35 mL
10 mM 0.57 mL 2.84 mL 5.67 mL
50 mM 0.11 mL 0.57 mL 1.13 mL

Pain Poster

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
