Western blot tests take only one day to perform, but some laboratories may not run the test every day. The name, 'western' blot, was first coined by Dr. Burnette in 1981 after the eponymous southern blot for DNA and consequent coinage of the northern blot in 1977 for RNA. If the first step is positive or indeterminate (sometimes called "equivocal"), the second step should be performed. Western blotting is a technique that uses specific antibodies to identify proteins that have been separated based on size by gel electrophoresis. Maintain constant agitation for 30 min at 4°C. PCR results, though not complete, point to the major problem of Western blot (WB) negative sera that prove positive for the viral genome and have to be excluded from screening for blood and organ donation. Place the membrane into an imaging tray. Pascal’s Law: All You Need to Know about this Powerful Law!
