Opis

General description

Denhardt′s Solution is a blocking agent routinely used to reduce non-specific binding of detection reagents to the Northern and Southern Blot membranes. This powder can be used to make a 50x concentrate that can be diluted to any concentration for use in a variety of pre-hybridization and hybridization buffers.

Application

Suitable as a blocking Buffer for Southern and Northern blot membranes.

Denhardt′s Solution has been used:

• as a component in hybridization buffer for the hybridization of brain sections
• in in-situ hybridization peroxidase-(antiperoxidase method-whole mounts) (ISH_PAP-WM) process
• in the preparation of hybridization mixture[1]

Biochem/physiol Actions

Denhardt′s solution and gelatin-chrome alum can be used to treat chromosomes for G-banding with trypsin after in situ hybridization.[2]

Preparation Note

Each vial of Denhardt′s powder contains 50mg Bovine Serum Albumin (BSA), 50mg Ficoll, and 50mg Polyvinylpyrrolidone (PVP).
