These findings demonstrate that β-actin is present in human plasma and may possibly be used as a suitable loading control for plasma-based Western blot analysis in major depressive disorder.Ĭopyright © 2012 Elsevier Inc. Western blotting has three basic elements: 1 separation of proteins by their size. , 1979), this immunodetection technique has been widely utilized to identify specific proteins in complex mixtures extracted from cells or tissues. Moreover, the total coefficient of variation for β-actin expression in the two groups was 9.2☑.2%. Ever since the first publication describing Western blotting (Renart et al. The data revealed no statistically significant difference between these two groups. Furthermore, the expression of plasma β-actin in major depressive disorder subjects and healthy controls was compared. Brief Description The COX IV (said Cox 4) antibody is reactive with the COX IV protein, generally expressed at a consistent high level, this antibody makes an effective loading control for mitochondria. In addition, the linearity of β-actin immunostaining and loaded protein amount was evaluated by Western blot, and a fine linearity (R²=0.974☐.012) was observed. Cytochrome C Oxidase (COX IV) Suitable for Mitochondrial proteins. In this study, an enzyme-linked immunosorbent assay was used to determine the concentration of β-actin in human plasma, which is 6.29☐.54 ng/ml. Use our table below to help select a loading control for your sample type with a different molecular. Loading control antibodies for Western Blot. However, β-actin's presence in human plasma and this protein's putative role as a plasma-based loading control for Western blot analysis remain unknown. Detection of commonly used loading control protein SMA.Pooled pregnant human myometrial tissue homogenates extracted in 2D lysis buffer were run in 2-fold serial dilutions from 40 g to 40 ng of total protein lysate per lane. Proteintech tag and control antibodies are 169 each (169 in Europe), including popular controls such as GAPDH, Tubulin and Actin. On account of its relatively high and constant expression, β-actin has been widely employed in Western blot of cell cultures and tissue extracts. For developers - Fiji is an open source project hosted in a Git version control repository, with access to the source code of all internals, libraries and. Ever since the first publication describing Western blotting (Renart et al., 1979), this immunodetection technique has been widely utilized to identify specific proteins in complex mixtures extracted from cells or tissues. For normalization of protein levels in Western blot, a suitable loading control is required. Loading controls in western blotting application. Western blot analysis is a commonly used technique for determining specific protein levels in clinical samples.
