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

Bile Acids

The liver excretes excess cholesterol in the form of bile acids. Bile acids serve two purposes: to remove unwanted cholesterol from the body and to aid in lipid digestion in the intestine.

Protocols

Enzymatic Assay of Cholesterol Oxidase

This procedure applies to products that have a specification for the enzymatic activity of cholesterol oxidase. This assay is NOT to be used to assay Cholesterol Oxidase from Schizophyllum commune (Discontinued Product Number C7274) and from Brevibacterium sp. (Discontinued Product Number C8153).

Immunoprecipitation Procedure

To determine the molecular weights of protein antigens, to study protein/protein interactions, to determine specific enzymatic activity, to monitor protein post-translational modifications and to determine the presence and quantity of proteins.
