AbVideo™ - Western Blot Membrane Stripping

Blot Imaging with X-Ray Film

An X-ray film can detect both the radioactive and chemiluminescent signals from Western, Northern or Southern blot. It is placed against the blot membrane in a light-proof cassette. After the exposure for an appropriate time period, the film is developed by an auto-processor in a darkroom.

Northern Blot

The northern blot is used to study gene expression by detection of RNA (or isolated mRNA). A general blotting procedure starts with the separation of RNA by electrophoresis. The RNA can then be transferred to a nylon membrane through a capillary system and detected with a hybridization probe.

Southern Blot

The Southern blot is used to detect a specific DNA sequence in DNA samples. A general blotting procedure starts with the separation of digested DNA fragments. The DNA can then be transferred to a nylon membrane through a capillary system and detected with a hybridization probe.

Western Blot

Western Blotting is an analytical technique used to detect specific proteins in a given sample. It uses gel electrophoresis to separate native or denatured proteins by the length of the polypeptide. The proteins are then transferred to a membrane where they are detected using antibodies specific to the target protein.

Western Blot - Ponceau S Staining

Ponceau S is a rapid and reversible staining method for locating protein bands on Western blots producing reddish pink stained bands. The stain is useful because it does not appear to have a deleterious effect on the sequencing of blotted polypeptides and can be completely removed from the protein bands by continued washing.
