Thermo Scientific Pierce Formaldehyde Ampules are vials of high-quality, methanol-free formaldehyde for use as a general IHC fixative and reversible amine-crosslinking agent for protein and nucleic acid tissue samples.
The availability of a high-quality, ampule-sealed solution of formaldehyde saves valuable time and eliminates the need and hazards associated with preparing the solution directly from paraformaldehyde. Pierce Formaldehyde is carefully prepared directly from granular paraformaldehyde and sealed under an inert atmosphere in 1 mL and 10 mL ampules. Ampule packaging stabilizes the preparation by protecting the solution from both air oxidation and light, allowing access to 'fresh' formaldehyde every time.
Features of Methanol-free 16% Formaldehyde Ampules:
• Fresh—formaldehyde solution remains stable and free of contamination in an amber pre-scored ampule.
• Sized Right—package sizes geared for applications ranging from culture-targeted cell fixing to in-cell protein-based applications.
• Convenient Starting Concentration—16% w/v formaldehyde solution simplifies dilution to the required working concentration.
• Minimizes Waste—1 mL and 10 mL package sizes allow selection of product that will result in less waste and minimize disposal concerns.
Application-targeted ampule packaging
The package sizes of the 16% Formaldehyde Solution (formalin) are targeted to both low and high volume users. The appropriate package size is selected based on the most common applications requiring a fresh, methanol-free formaldehyde solution. The 16% (w/v) solution simplifies the dilution for each respective application and the application-directed packaging minimizes waste.
• 1-mL ampules are intended for protein-based in cell applications such as Chromatin Immunoprecipitation (ChIP) or protein interaction discovery.
• 10-mL ampules are intended for bioimaging (high content screening/analysis) such as fixing cells on a culture plate before image analysis.
'Prepared fresh' Sealed in Ampules
Our formaldehyde solution is prepared as a 16% (w/v) solution of paraformaldehyde (pure granular solid) in distilled/deionized water. Solution stabilization is important because formaldehyde solutions oxidize to formic acid and eventually repolymerize to paraformaldehyde. Most protocols requiring methanol-free formaldehyde suggest that the formaldehyde be 'prepared fresh'. This formaldehyde solution is sealed in ampules immediately after formulation under an inert atmosphere. Ampule packaging stabilizes the preparation allowing access to 'fresh' formaldehyde each time.
For added safety when opening glass ampules, consider using our Ampule Breakers, which are disposable safety devices that protect the fingers when breaking open a glass ampule.
