TMB Stabilized Substrate for Horseradish
Peroxidase
Product Size Cat.# Price ($)
TMB Stabilized Substrate for Horseradish
Peroxidase 200 ml W4121 282.00
For Research Use Only. Not for Use in Diagnostic Procedures.
Description: TMB Stabilized Substrate is a stable, ready-to-use TMB (3,3´,
5,5´-tetramethylbenzidine) color development substrate for localization of
horseradish peroxidase-conjugated antibodies on dot blots and Western blots.
It is easier to use than 4-chloro-1-naphthol (CN), which must be prepared
immediately before use. TMB Stabilized Substrate comes premixed and fully
diluted in a proprietary buffer containing less than 0.5% organic solvent.
Features:
• Convenient: Premixed, ready-to-use; in proprietary buffer containing less
than 0.5% organic solvents.
• Stable: Stable at room temperature for 12 months.
• Sensitive: At least threefold more sensitive than 4-chloro-1-naphthol (CN);
as little as 412pg of β-galactosidase detected on TMB blot as compared to
1.12ng on CN blot when detected with a β-galactosidase-specific antibody
and HRP-conjugated secondary antibody.
• Long-Lasting Color: Color is much more stable than 4-chloro-1-naphthol
and photographs more easily.
Storage Conditions: Store at 22–25°C.
