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.

Western blot analysis of extracts from various cell lines using SMAD4 (D3M6U) Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower). HT-29 and COLO 205 are SMAD4-null mutant cell lines, confirming specificity of the antibody.

Product 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.

Specificity / Sensitivity

Each antibody in the SMAD2/3 Antibody Sampler Kit recognizes only its specific target and does not cross-react with other family members. Activation state antibodies detect their intended targets only when phosphorylated at the indicated site. The total SMAD2, SMAD3, and SMAD4 antibodies detect their respective targets at endogenous levels.

Source / Purification

Phospho-specific monoclonal antibodies are produced by immunizing animals with synthetic phosphopeptides corresponding to residues surrounding Ser465/467 of human SMAD2 or Ser423/425 of human SMAD3 protein. Total SMAD2, SMAD3, and SMAD4 monoclonal antibodies are produced by immunizing animals with synthetic peptides corresponding to residues near the amino termini of mouse SMAD2 and SMAD3, surrounding His198 of human SMAD2/3, or surrounding Asp165 of human SMAD4 protein.

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).
