Anti actin ab

Manufactured by Merck Group
Sourced in United Kingdom, United States, Canada

Anti-actin Ab is a laboratory reagent used for the detection and quantification of actin, a ubiquitous cytoskeletal protein, in various biological samples. It functions as a specific antibody that binds to actin, allowing researchers to analyze the expression, localization, and dynamics of this essential cellular component.

Immunofluorescence Analysis of Endometriotic Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human primary endometriotic stromal cells that were previously transfected with either the control vector or the shOCT4 plasmids were treated with or without TGF-βI (1 ng/mL). The cells were then fixed with 0.05% glutaraldehyde at room temperature for 15 minutes and blocked in 50 mg/mL of bovine serum albumin and 0.5% Triton X-100 in phosphate-buffered saline (pH 7) for 1 hour at room temperature. The blocked cells were incubated with an anti-Actin Ab (Sigma-Aldrich), and the bound primary Ab was detected with a FITC-conjugated secondary Ab (Jackson ImmunoResearch). The nuclei of the cells were counterstained with 4',6-diamidino-2-phenylindole (DAPI) (Sigma-Aldrich, St. Louis, MO, USA), and the cells were covered with an antifading reagent (Vector Laboratories, Burlingame, CA, USA) before examining them under a confocal-imaging fluorescence microscope (Leica, Buffalo Grove, IL, USA).

HEK293T cells were transfected with pCMV-cGAS (Origene), pCMV-STING (Origene) or pcDNA3.1 vector (60 ng DNA). Cells were trypsinized 24 post transfection and re-plated individually or mixed at 1:1 ratio, such that each well contained a total of 4 × 105 cells/well in a 24 well dish. Cells were infected, or permeabilized with positive control ligands cGAMP (1µg/ml) or transfected with ISD (1µg), 6 hours after plating and harvested at indicated times and processed for RNA and qRT-PCR. Immunoblots for cGAS or STING protein in HEK293, HEK293T and HeLa cells were carried out using cell lysate prepared using RIPA buffer (Pierce-Thermo Scientific) and protease inhibitor cocktails (Sigma). Anti cGAS Ab (Cat# AP10510c, Abgent), anti-STING poly clonal Ab (Cat# PA5-26751, Thermo Scientific) and anti-actin Ab (Cat# A2228, Sigma) were used at the 1:500, 1:500 and 1:1000 concentration respectively.

Proteins from CMs extracts were separated by SDS-polyacrylamide gel electrophoresis (4–12% Bis-Tris Criterion BIO-RAD gels), blotted for 1 h, incubated with polyclonal anti-SERCA2 primary antibody (N-19; Santa Cruz Biotechnology) at 4°C overnight, followed by incubation with a specific secondary antibody labeled with fluorescent markers (Alexa Fluor or IRDye) for 1 h. Signal intensity was quantified by Odyssey Infrared Imaging System (LI-COR). SERCA2 protein levels were normalized to actin levels, as measured using polyclonal anti-actin Ab (Sigma). Data are shown as percent changes vs. Ctrl.

AMPA and NMDA receptor subunit analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
The AMPA receptor subunits were analysed by means of Western blotting as previously described [36] . For AMPA receptor subunit detection we used anti-GluA2-3 and anti-GluA1 antibodies (Abs) produced and characterised by us as described in [36] (see supplementary figure 2). For NMDA receptor subunit detection we used anti-GluN2A (clone A3-2D10, Life technologies, Waltham, MA, USA), anti-GluN2B (clone N59/20; Antibodies Incorporated, Davis, CA, USA), anti-NR1 subunit Ab produced by us and analysed in [37] ; We also used anti-PSD95 Ab (clone K28/43, Antibodies Incorporated, Davis, CA, USA) and anti-actin Ab (clone AC-40; Sigma-Aldrich, St. Louis, MO, USA).
For AMPA and NMDA receptor subunits and PSD the signal was normalised to the actin content and the values were normalised by taking the mean values of the AIR exposed mice as one.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
