Western Blot - Wikipedi

Western blotting is a technique that uses specific antibodies to identify proteins that have been separated based on size by gel electrophoresis. The immunoassay uses a membrane made of nitrocellulose or PVDF (polyvinylidene fluoride). The gel is placed next to the membrane and the application of an electrical current induces the proteins to migrate from the gel to the membrane. The membrane. ASSIGNMENT: BLOTTING TECHNIQUES BLOTTING TECHNIQUES Blotting is generally done by letting a mixture of DNA, RNA or protein flow through a slab of gel. This gel allows small molecules to move faster than bigger ones. The separated molecules are then pressed against a membrane, which helps move the molecules from the gel onto the membrane. The molecules stick to the membrane, but stay in the. Western blot protocol with workflow steps for different blot procedures, describing the electrophoretic transfer of proteins from SDS polyacrylamide gels to sheets of nitrocellulose. Also known as Immunoblotting protcol All blotting techniques are based on the same principle of specific base pairing of the probe sequences to the sequences immobilized on the membrane. Any change in the sample sequences will lead to the probes not binding or binding non-specifically. This change in binding affinity will be visualized upon secondary hybridization with a labeled probe. The intensity of the resultant dye or.
