UREA

尿素（高纯级）

Description

Commonly used to denature nucleic acids for electrophoresis and to study the secondary and tertiary structure of proteins. Effective for maintaining DNA in a highly denatured state during sequencing protocols, urea is also useful for accelerating the activity of Proteinase K digestions.
