Western blot analysis of beta-actin in various tissues and cell lines using Proteintech antibody 66009-1-Ig at a dilution of 1:20000 (Exposure time: 10 seconds).īeta-actin has been implicated in hand, foot, and mouth disease by proteomics and large diffuse B-cell lymphoma (3, 4). Rabbit polyclonal antibody to beta actin, which is also known as PS1TP5BP1 and BRWS1. This is essential in some experimental systems where it may not be possible to always collect the exact same number of cells for each sample, such as when working with primary cells, tissue samples, or systems where you may be altering protein synthesis, cell size/number, or apoptosis (1).įigure 3. In Western blotting, beta-actin (42 kDa) is commonly chosen as a loading control due to its broad and consistent expression across all eukaryotic cell types and the fact that expression levels of this protein are not affected by most experimental treatments (Figure 3).Beta-Actin runs as a “loading control” to show that very similar amounts of protein were loaded in each lane. They can be used to normalize the levels of protein detected by confirming that protein loading is the same across the gel. Loading controls are essential for proper interpretation of Western blots. Why is beta-actin commonly used as a control in Western blots? Since the immunogen for 60008-1-Ig is the internal sequence, this antibody can recognize a wide range of species and can be broadly used in research. However, the N-terminal sequence is less conserved among species than the C-terminus. Proteintech’s monoclonal beta-actin antibody ( 60008-1-Ig ) (Figure 1) recognizes all fragments, while 66009-1-Ig antibody (Figure 2) can only detect the full length of beta-actin. Beta-actin is highly conserved among species. Though beta-actin has a molecular weight of 42 kDa, degradation by apoptosis will produce 38-41 kDa fragments on a Western blot. Four of these isoforms are expressed primarily in striated and smooth muscle cells, whereas beta-actin and gamma-actin isoforms are ubiquitously expressed. Beta-actin – a housekeeping protein Why is beta-actin commonly used as a control in Western blots? beta-actin and human diseases Related products ReferencesĪctin is a major component of the cytoskeleton, with six known isoforms in mammals.
