Sufficient For Applications requiring 1mL aliquots
Description Pierce 16% Formaldehyde (w/v), Methanol-free
Quantity 10 x 1mL

Formaldehyde is a highly reactive, cell-permeable agent that is used as a reversible cross-linking agent for proteins and nucleic acids within the cell or as a general cell-fixing agent for imaging-based applications. Cell permeability allows the reagent to readily enter living cells, enabling intracellular applications, such as protein interaction discovery or bioimaging. Formaldehyde produces reversible cross-links with protein and nucleic acids by coupling neighboring primary amines. Cross-links can be reversed simply by heating the sample.


  • Pure and stable - prepared directly from pure granular paraformaldehyde and sealed in ampules under an inert atmosphere, ensuring that it is methanol-free and resistant to oxidation

  • Versatile - use to cross-link molecules in protein-protein and protein-nucleic acid interaction discovery, bioimaging and flow cytometry

  • Aliquot packaging - choose 1mL or 10mL ampules suitable for low- and high-volume applications ranging from culture-targeted cell fixing to in-cell protein cross-linking

  • Convenient starting concentration - 16% (w/v) formaldehyde solution in ultrapure water simplifies dilution to the required working concentration
