A Brief Look of Western Blot Technique

Hesperian blotting is a sympathetic of interbred framework that combines high-resolution gel action with immunochemical analysis techniques. Occidental error, collective with a tracheophyte of advantages, including huge loudness, towering predisposition and piping specificity of analysis, etc, is a frequently-used method to detect proteins’ characteristics, demo and organization, including but not restricted to qualitative and decimal espial of tissue antigens, quality finding of polypeptide molecules and antibody or antigen reception of viruses.

Employed theory

The integrated antigen samples are distributed by unidirectional or bidirectional dielectrolysis on the gel brace, and then immobilized matrix membrane is practical to the gel. The single antigen element in the gel is transferred to the printed paper and solid-phase with the improve of the unaffected sorption unit, automobile tract organisation or else extrinsic forces. And then, the immobilized matrix membrane was detected and analyzed by immunocovering solvent skillfulness,much as an immunoisotope perforate or immunoenzyme penetrate.


Northwestern blotting is a technique for analyzing antigens and antibodies. It has shadowing advantages:

The wet immobilized matrix picture is supple and casual to manipulate;
Immobilized biomolecules can be uniformly immediate to various transmitter probes, and module not be choked by pore filler equivalent gel;
Sandwich blot reasoning requires only a small quantity of reagent;
The birthing and lavation indication was significantly reduced;
Treble copies can be prefabricated simultaneously for binary psychotherapy and remembering;
The results can be frozen for a oblong instant in the work of column;
The unsusceptible examine can be removed by sullen the PH appraise and another methods, removing the oftenness tape, and then the secondment examine can be old for psychotherapy and detection. The application range and advantages of western blotting are not qualified to this.
