Anti a20 antibody

Manufactured by Cell Signaling Technology
Sourced in United States

The Anti-A20 antibody is a laboratory tool used to detect and study the A20 protein, which is a key regulator of inflammatory and immune responses. This antibody specifically binds to the A20 protein, allowing researchers to investigate its expression, localization, and interactions within cells and tissues.

Western Blot Analysis of A20 Protein

Check if the same lab product or an alternative is used in the 5 most similar protocols
The 293T cells transfected with Gas-miR01/Gas-miR02/NC mimics were collected, and then the total proteins were extracted using the Cell Lysis Reagent (Roche). Total proteins were separated by 12% SDS-PAGE and transferred onto a polyvinylidene difluoride (PVDF) membrane (Millipore, USA) by electroblotting. After blocking with 5% skim milk in tris-buffered saline with Tween (TBST) (pH 7.4) for 2 h at room temperature, the protein was detected with an anti-A20 antibody (Cell Signaling Technology, USA) overnight at 4°C. The membrane was washed with TBST, and HRP-labeled (horseradish peroxidase-labeled) mouse anti-rabbit antibody was used as the secondary antibody (Cell Signaling Technology, USA). The signals were detected using the ECL Detection Kit (Advansta).

Co-Immunoprecipitation of ABIN1 and A20

Check if the same lab product or an alternative is used in the 5 most similar protocols
The peri-infarct cortex was homogenized in IP lysis buffer (Beyotime, China) to extract the proteins. One microgram of anti-ABIN1 antibody (#4664, Cell Signaling Technology), anti-A20 antibody (#5630, Cell Signaling Technology), or normal rat IgG was added to each milligram of total protein in the supernatants, and the samples were rotated at 4°C overnight. Forty microliters of protein A/G agarose beads was mixed with the supernatants and rotated at 4°C for 2 h. The beads were washed with lysis buffer and then eluted with 40 μl of SDS loading buffer. The supernatants were collected for western blot.

Ubiquitination Pathway Regulates CXCL10 Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
A20 protein levels were determined in cytosolic extracts by western blot as described above. Anti-A20 antibody (Cell Signaling) was used at 1:1000 dilution and anti-β-tubulin antibody (Santa Cruz Biotechnology, Santa Cruz, CA, USA) was used at 1:200 dilution as a loading control. The involvement of the ubiquitination pathway in IL-1β-induced CXCL10 expression in NHA was assessed using PYR41 (4 nM, Tocris Bioscience, Minneapolis, MN) a cell permeable inhibitor of ubiquitin (Ub)-activating enzyme E1, to block signaling through this pathway. Thus, cells were co-exposed to IL-1β and PYR41 for 24 h, followed by measurement of CXCL10 in media by ELISA.
For all studies, total cellular/nuclear protein levels were determined using the bicinchoninic acid (BCA) protein assay to normalize data when appropriate (Davis et al., 2002 (link)).

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.
