Pricing Availability Delivery Time Qty
Cat.No. 4981 - Cystamine dihydrochloride | C4H12N2S2.2HCl | CAS No. 56-17-7
Description: Transglutaminase inhibitor; neuroprotective
Chemical Name: 2,2'-Diaminodiethyl disulfide dihydrochloride

Biological Activity

Transglutaminase inhibitor. Attenuates cell death induced by 3-nitropropionic acid (Cat. No. 4849) in Huntington's disease (HD) striatal cells. Also decreases aggregated and cross-linked huntingtin in transfected cells, and increases brain levels of BDNF. Shown to extend survival and improve motor performance in transgenic HD mice. Neuroprotective.

Preparing Stock Solutions

The following data is based on the product molecular weight 225.2. 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 4.44 mL 22.2 mL 44.4 mL
5 mM 0.89 mL 4.44 mL 8.88 mL
10 mM 0.44 mL 2.22 mL 4.44 mL
50 mM 0.09 mL 0.44 mL 0.89 mL
