β-Actin与GAPDH内参真的那么靠谱吗? 哪种内参最靠谱? 免疫印迹(Western blot, WB)是分子生物学中检测复杂生物提取物中特定蛋白质存在的最常用方法之一 Western blotting is used to visualize proteins that have been separated by gel electrophoresis. The gel is placed next to a nitrocellulose or PVDF (polyvinylidene fluoride) membrane and an electrical current causes the proteins to migrate from the gel to the membrane. The membrane can then be probed by antibodies specific for the target of interest, and visualized using secondary antibodies and detection reagents For western blotting, we have tested and recommend using the antibody at a concentration of 500 ng/ml (1:1000 dilution). At this dilution, we detected actin in cell extracts of Xenopus A6 cells, mouse Swiss 3T3 cells, rat NRK cells, human HeLa cells, and platelet cells The beta actin bands on my western blot are showing at various widths and intensities even in samples that are duplicates of each other (same protein lysate, same amount loaded, ect.)

β-actin belongs to a class of genes called housekeeping genes.Their proteins typically perform functions that are required across essentially all cell types (for example, β-actin is part of the cytoskeleton's microfilaments), and are supposed * to be not affected by experimental conditions. In Western blotting, they are run as a loading control to show that very similar amounts of protein. 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 Loading Control Antibodies - Generate publication quality Western blots.

Western blotting is considered the gold standard for protein detection and quantification in molecular biology research. Beta-actin Not suitable for nuclear extract as beta-actin is a component of chromatin remodeling complexes. May not be suitable for studies involving subjects with a large age difference Western blot allows us to determine the relative protein levels between samples and establish the molecular weight of the target, which can provide insight into its post-translational processing. To achieve this, western blot implements three steps: (1) separation by size, (2) transfer to a solid support, and (3) visualizing target protein using primary and secondary antibodies Western Blot 22.
