Background:

Smad3 is a 50 kDa member of a family of proteins that act as key mediators of TGF beta superfamily signaling in cell proliferation, differentiation and development. The Smad family is divided into three subclasses: receptor regulated Smads, activin/TGF beta receptor regulated (Smad2 and 3) or BMP receptor regulated (Smad 1, 5, and 8); the common partner, (Smad4) that functions via its interaction to the various Smads; and the inhibitory Smads, (Smad6 and 7). Activated Smad3 oligomerizes with Smad4 upon TGF beta stimulation and translocates as a complex into the nucleus, allowing its binding to DNA and transcription factors. Phosphorylation of the two TGF beta dependent serines 423 and 425 in the C terminus of Smad3 is critical for Smad3 transcriptional activity and TGF beta signaling.

VALIDATION IMAGES

Lane 1: Human HUVEC cell lysates; Lane 2: Human Hela cell lysates; Lane 3: Human HT1080 cell lysates; Lane 4: Human A431 cell lysates; Lane 5: Human A549 cell lysates probed with Smad3 (Ser208) Polyclonal Antibody, Unconjugated (bs-5617R) at 1:1000 dilution and 4˚C overnight incubation. Followed by conjugated secondary antibody incubation at 1:20000 for 60 min at 37˚C.


A431 cells were fixed with 4% PFA for 10min at room temperature,permeabilized with 90% ice-cold methanol for 20 min at -20℃, and incubated in 5% BSA blocking buffer for 30 min at room temperature. Cells were then stained with Smad3 (Ser208) Polyclonal Antibody(bs-5617R)at 1:100 dilution in blocking buffer and incubated for 30 min at room temperature, washed twice with 2%BSA in PBS, followed by secondary antibody incubation for 40 min at room temperature. Acquisitions of 20,000 events were performed. Cells stained with primary antibody (green), and isotype control (orange).
