Background

Iodoacetamide is a useful alkylating reagent that modifies cysteine residues so that they can no longer create disulfide linkages. This prevents proteins from refolding and helps to keep them in their primary linear structure to better enable protease digestion and peptide sequencing. This is an irreversible reaction and can also be used for inactivation of enzymes or improved resolution by electrophoresis, where disulfide bonds could potentially reform.

Description

Iodoacetamide is recommended for use in our PTMScan® protocols when making tissue or cell lysates just prior to the digestion steps.

Molecular Formula

C2H4INO

Purity

Greater than or equal to 99%

CAS

Storage

Store lyophilized powder at 4°C, desiccated and protected from light.

Directions for Use

1. Weigh out 95mg of iodoacetamide and protect from light.

2. Add reverse osmosis deionized (RODI) water or equivalent to a final volume of 5 ml immediately before use.

Note: The iodoacetamide solution should be prepared fresh prior to each experiment.
