Description

The SMAD2/3 Antibody Sampler Kit provides an economical means of detecting target proteins of the TGF-β signaling pathway. The kit includes enough antibody to perform two western blots with each primary antibody.

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Background

Transforming growth factor-β (TGF-β) superfamily signaling plays a critical role in the regulation of cell growth, differentiation, and development in a wide range of biological systems. In general, signaling is initiated with ligand-induced oligomerization of serine/ threonine receptor kinases and phosphorylation of the cytoplasmic signaling molecules Smad2 and Smad3 for the TGF-β/activin pathway, or Smad1/5/8 for the bone morphogenetic protein (BMP) pathway. Carboxy-terminal phosphorylation of Smad proteins by activated receptors results in their partnering with the common signaling transducer Smad4, and translocation to the nucleus. Activated Smad proteins regulate diverse biological effects by partnering with transcription factors resulting in cell-state specific modulation of transcription (1-4).

    Simple Western™ analysis of lysates (1.0 mg/mL) from serum starved HT-1080 cells treated with hTGF-β3 (10 ng/mL, 30 min) using Phospho-SMAD2 (Ser465/467) (138D4) Rabbit mAb #3108. The virtual lane view (left) shows a single target band (as indicated) at 1:50 and 1:250 dilutions of primary antibody. The corresponding electropherogram view (right) plots chemiluminescence by molecular weight along the capillary at 1:50 (blue line) and 1:250 (green line) dilutions of primary antibody. This experiment was performed under reducing conditions on the Jess™ Simple Western instrument from ProteinSimple, a BioTechne brand, using the 12-230 kDa separation module.
