Features and Benefits
Non-toxic Reagents SystemsWith conventional electrophoresis reagents, there is always a risk to health. By contrast, the reagents in the ATX reagent system are non-toxic, environmentally friendly. Conventional reagents contain various toxic substances: buffer solutions contain barbituric acid, classified as a narcotic according to the Dangerous Drugs Act; staining solutions contain methanol and acetic acid which irritate the skin and airways; clarifying solutions contain methanol and dioxan isobutanol, a carcinogenic, inflammable substance which is classified as hazardous waste. Stop using these toxic substances. For your electrophoresis, start using the non-toxic ATX reagent system and protect yourself and the environment against permanent damage.The advantages are clear. ATX reagents are:
• non-toxic and non-irritant to skin and airways
• environmentally friendly
• disposable with regular waste water
• odorless
• non-inflammable
• stable at room temperature
• specially coordinated with ATX micro-solid strips
• available as ready-to-use solutions or as concentrates
• guaranteed to give excellent, reproducible results
Packaging
6 bottles for the preparation of 250 mL ready-to-use-solution

Application
Ponceau S dye is used to make a stain for rapid reversible staining of protein bands on nitrocellulose or PVDF membranes (Western blots) and also for staining protein on cellulose acetate membranes. The following are two common stain formulations;0.1% Ponceau S (w/v) in 5% acetic acid2% Ponceau S (w/v) in 30% TCA, 30% sulfosalicylic acid

Sigma Aldrich - P7170

Application
Ponceau S stain comes ready-to-use and is designed for rapid (5 min) staining of protein bands on nitrocellulose or PVDF membranes (Western blots) and also for staining protein on cellulose acetate membranes. Ponceau S staining on nitrocellulose and PVDF is reversible by washing the stained membrane with 0.1 M NaOH for 1 min. The stained and destained membrane can then be immunologically detected (Western blotting). A product information sheet is supplied which includes the staining procedure for cellulose acetate, nitrocellulose, and PVDF.
