Description générale

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

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) (ISHPAP-WM) process
  • in the preparation of hybridization mixture

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

Actions biochimiques/physiologiques

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

Composants

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

Notes préparatoires

To make a 50x concentrate, dissolve entire contents of vial in 5 mL molecular biology grade water. Store at -20°C for up to two years.

The extracellular matrix glycoprotein, tenascin, is associated in vivo with mesenchyme undergoing osteogenesis and chondrogenesis, but is absent from mature bone and cartilage matrix. The expression of tenascin by osteoblastic cells in vitro has been investigated by immunoblotting and immunocytochemistry.

Vaccinia virus (VV) mutants lacking the double-stranded RNA (dsRNA)-binding E3L protein (ΔE3L mutant VV) show restricted replication in most cell types, as dsRNA produced by VV activates protein kinase R (PKR), leading to eIF2α phosphorylation and impaired translation initiation. Here

It has long been a question whether Staphylococcus aureus, a major human pathogen, is able to develop natural competence for transformation by DNA. We previously showed that a novel staphylococcal secondary sigma factor, SigH, was a likely key component for
