All primary antibodies used in the present study are listed in Star Methods Table S1. Secondary horseradish peroxidase (HRP)-conjugated goat anti-mouse and anti-rabbit antibodies were from BioRad. All secondary antibodies for immunofluorescence were from goat host, conjugated to Alexa-dyes (Life Technologies). Exclusively isotype-specific secondary antibodies were used against monoclonal mouse antibodies. Alexa555-tagged Phalloidin was from Life Technologies.
Synthetic peptides were purchased from ChinaPeptides (Shanghai, China). Calmidazolium and W7 were bought from Tocris, and TFP from MP Biomedicals. All reagents used for cloning were obtained from New England Biolabs (NEB). If not specifically stated, all other reagents were of standard quality and from the usual vendors.

All chemicals utilized for the experiments were purchased from Sigma‐Aldrich Chemicals unless otherwise indicated. Intravenous dyes such as Alexa 555 tagged phalloidin (Life Technologies Inc.) was superfused to highlight intracellular actin dynamics. Intracellular reactive oxygen species (ROS) were detected by the IMAGE‐iT LIVE Green ROS Detection Kit which consists of 5‐(and‐6)‐carboxy‐2',7'‐dichlorodihydrofluorescein diacetate (carboxy‐H2DCFDA, Life Technologies Inc.). To determine intracellular mitochondrial activation, mitochondrial redox potential was imaged using reduced mitotracker orange (Life Technologies Inc.).

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.
