SNOB 1 reagent

Discontinued Product

Unfortunately SNOB 1 reagent (Cat. No. 3879) has been withdrawn from sale for commercial reasons.
Cat.No. 3879 - SNOB 1 reagent | C13H21N3O2S | CAS No. 92924-45-3
Chemical Name: (3S,4S,6R)-5-{2-Oxo-hexahydro-1H-thieno[3,4-d]imidazolidin-4-yl}-N-(prop-2-en-1-yl)pentanamide
Purity: ≥98% (HPLC)

Biological Activity

S-nitrosylated binding (SNOB) reagents detect cysteine residues that have been S-nitrosylated by nitric oxide. SNOB 1 can be used as part of a single-step assay to label S-nitrosylated proteins with biotin for detection by Western blotting or proteomic analysis. Negative SNOB 1 control (Cat. No. 3880) available.
