General description

Triton X-100 is a common non-ionic surfactant and emulsifier which is often used in biochemical applications to solubilize proteins. It is considered a comparatively mild detergent, non-denaturing, and is reported in numerous references as a routinely added reagent. It is utilized for lysing cells to extract protein and cellular organelles. It can also permeabilize the living cell membrane for transfection.
Triton X-100 has hemolytic property and is used for DNA extraction.

Application

Triton-X has been used:
  • In the permeabilization of cells for immunofluorescence staining
  • As a component of lysis buffer in western blot analysis
  • As a component of Tris-buffered saline for the preparation of cell sections in Immunogold labelling for electron microscope

Packaging

5 mL in glass bottle
1 gal in poly bottle
5 gal in poly drum
1 L in poly bottle
100, 500 mL in poly bottle

Biochem/physiol Actions

Widely used non-ionic surfactant for recovery of membrane components under mild non-denaturing conditions.

  1. What is the molecular weight of X100, Triton® X-100?

    Based on an average of 9-10 ethylene oxide units per molecule, the molecular weight of Triton X-100 is 625 g/mol.

  2. What is the concentration of X100, Triton® X-100?

    This product is 100% active ingredient.

  3. What concentration of X100,Triton® X-100, is typically used to lyse cells?

    Typically, a 0.1 % solution of Triton X-100 is sufficient for lysing cells.

  4. Does X100, Triton® X-100, have any UV absorbance?

    X100 does have UV absorbance at 280 nm, which will interfere with the UV determination of proteins.

  5. Can I autoclave X100, Triton® X-100?

    Aqueous solutions of Triton X-100 are stable to autoclaving. At certain concentrations the solutions may be cloudy but dispersible above the cloud point. However, the solution should clear with stirring upon cooling.
