Anti cx43

Manufactured by BD
Sourced in United States

Anti-Cx43 is a laboratory reagent used for the detection and analysis of the protein Connexin 43 (Cx43) in biological samples. Cx43 is a key component of gap junctions, which facilitate intercellular communication. Anti-Cx43 can be used in various research applications, such as immunohistochemistry, Western blotting, and cell biology studies.

Extracted protein were loaded into polyacrylamide gels and transferred onto PVDF membranes. The membranes were blocked in 5% nonfat milk containing 0.3% tween 20, and then probed with anti-Cx43 (BD Transduction Labs), anti-fibronectin (BD Transduction Labs), anti-β-actin (sigma), anti-GAPDH (Abcam), anti-α-SMA (Abcam) p-smad2/3 (Abcam), TGFβR2 (Abcam) or anti-S100A4 (Abcam) antibody at 4°C overnight. After washing, the membranes were incubated with horseradish peroxidase-linked secondary antibody, and bands were visualized using enhanced chemiluminescence system (GE Healthcare) and then exposing the blots. Protein levels were quantified by scanning densitometry (Alpha Image).

The unfixed frozen wound tissues segments were sectioned with a cryostat and placed on glass slides. Cut OCT-embedded tissues sections (10μm thick) were stained with analyzed immunofluorescence. Block each section with 2% BSA blocking buffer for 60 min at room temperature. Incubation for overnight at 4℃ with anti-Cx43 (1:1000, BD Transduction Labs); anti-S100A4 (1:500, Abcam). Sections were washed then second antibody incubated for 2 hrs at room temperature l with fluorescence-conjugated secondary antibodies Alexa Fluor® 488 goat anti-mouse (Invitrogen, Carlsbad, CA) and Alexa Fluor® 594 goat anti-rabbit (Invitrogen, Carlsbad, CA). Measurement of green and red fluorescence labeling by a laser scanning were imaged by confocal imaging system.

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.
