Simple Western: ASC/TMS1 Antibody [NBP1-78977] - Lane view shows a specific band for ASC TMS1 in 0.5 mg/ml of MCF-7 lysate. This experiment was performed under reducing conditions using the 12-230 kDa separation system.Immunocytochemistry/ Immunofluorescence: ASC/TMS1 Antibody - BSA Free [NBP1-78977]
Immunocytochemistry/Immunofluorescence: ASC/TMS1 Antibody [NBP1-78977] - NLRP3 activation was evaluated by visualizing the co-localization of NLRP3 and apoptosis-associated speck-like protein (ASC) using immunocytochemistry (A).

Immunohistochemistry: ASC/TMS1 Antibody [NBP1-78977] - Rats were infected by S. pneumoniae or given PBS sham control. 21.5 umoles/kg Mito-Vit-E (MVE) or vehicle was administered orally 30 minutes post-inoculation, and heart tissues were harvested 24 hours later. Heart sections were co-stained with anti-ASC (brown) and haematoxylin (blue). Negative control was stained with secondary antibody alone. Images are representative of a random selection of at least 3 sections of N = 6. PLoS One. 2015 Oct 8;10(10):e0139416. doi: 10.1371/journal.pone.0139416.Applications for ASC/TMS1 Antibody - BSA Free

Background: ASC
In regard to immune and inflammatory response, ASC/TMS1 is involved in inflammasome function (3-4). The inflammasome is a multiprotein complex that responds to cellular stress or pathogens and activates inflammatory responses. Specifically, ASC/TMS1 helps assemble the NLRP3 inflammasome complex which then activates caspase-1, followed by stimulation of proinflammatory cytokines including IL-1b and IL-18 (3-4). In terms of the role in regulating apoptosis, multiple studies have revealed that the ASC/TMS1 gene is hypermethylated in many cancers including breast, lung, glioblastomas, and melanomas (2-5). The increased methylation results in decreased gene expression, or silencing, allowing those cancer cells to escape apoptosis (2-5).
