A Western Blot allows for the semiquantitative determination of protein expression.
Crude cell lysates are loaded into a polyacrylamide gel containing a denaturing agent which give all the proteins a net negative charge. A current can then be passed through the gel and the proteins will migrate through the gel, with the largest proteins traveling the slowest, resulting in a lane where proteins become separated on the basis of their weight. The proteins can then be transferred from the gel onto a membrane (often nitrocellulose or PVDF), which can then by incubated with an antibody directed against the protein of interest. By using a detector conjugated to an antibody one can now detect specifically the protein of interest.

The protein blot, also know as Western blot or immunoblot, is one of the most tried and true experiments for antibody-dependent determination of protein expression/presence in a sample. This pages directs you both to the general and lab-specific protocols regarding protein blotting.
