Western blot workflow. The western blot (sometimes called the protein immunoblot), or western blotting, is a widely used analytical technique in molecular biology and immunogenetics to detect specific proteins in a sample of tissue homogenate or extract. [1]
Normalization of Western blot data is an analytical step that is performed to compare the relative abundance of a specific protein across the lanes of a blot or gel under diverse experimental treatments, or across tissues or developmental stages.
A review on western blotting from 2006 describes Towbin as the author for W.blotting and Stark for Northern -- maxhebditch 14:10, 07/01/13 —Preceding undated comment added 14:12, 7 January 2013 (UTC) [ reply ]
A western blot is used for the detection of specific proteins in complex samples. Proteins are first separated by size using electrophoresis before being transferred to an appropriate blotting matrix (usually polyvinylidene fluoride or nitrocellulose ) and subsequent detection with antibodies.
"Our results document a fourth source of false positive HIV-1 Western Blot results, which is the reproducible but nonspecific reactivity to (proteins from HIV)... Preliminary studies suggest that the basis for this cross reactivity with HIV-1 gp 41 proteins may be infection by paramyxoviruses, carbohydrate antibodies, or autoantibodies against ...
In a generally healthy low-risk population, indeterminate results on western blot occur on the order of 1 in 5,000 patients. [15] However, for those individuals who have had high-risk exposures to individuals where HIV-2 is most prevalent, Western Africa, an inconclusive western blot test may prove infection with HIV-2.
