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

Members of the SMAD family of signal transduction molecules are components of a critical intracellular pathway that transmit TGF-β signals from the cell surface into the nucleus. Three distinct classes of SMADs have been defined: the receptor-regulated SMADs (R-SMADs), which include SMAD1, 2, 3, 5, and 9; the common-mediator SMAD (co-SMAD), SMAD4; and the antagonistic or inhibitory SMADs (I-SMADs), SMAD6 and 7 (1-5). Activated type I receptors associate with specific R-SMADs and phosphorylate them on a conserved carboxy-terminal SSXS motif. The phosphorylated R-SMADs dissociate from the receptor and form a heteromeric complex with SMAD4, initiating translocation of the heteromeric SMAD complex to the nucleus. Once in the nucleus, SMADs recruit a variety of DNA binding proteins that function to regulate transcriptional activity (6-8).

    PhosphoPlus® SMAD2 (Ser465/467) Antibody Duet

    PhosphoPlus® SMAD2 (Ser465/467) Antibody Duet: Image 1 Expand Image
    Western blot analysis of extracts from HaCaT cells, untreated (-) or treated with Human Transforming Growth Factor β3 (hTGF-β3) #8425 (100ng/ml, 30mins) (+), using Phospho SMAD2 (Ser465/Ser467) (E8F3R) Rabbit mAb (upper) and total Smad2 (D43B4) XP® Rabbit mAb, #5339 (lower).

    Western blot analysis of extracts from HeLa cells (lane 1) or SMAD2 knock-out cells (lane 2) using Smad2 (D43B4) XP® Rabbit mAb #5339 (upper), and α-Actinin (D6F6) XP® Rabbit mAb #6487 (lower). The absence of signal in the SMAD2 knock-out HeLa cells confirms specificity of the antibody for SMAD2.

    Immunoprecipitation of phospho-SMAD2 (Ser465/Ser467) from extracts of HaCaT cells treated with Human Transforming Growth Factor β1 (hTGF-β1) #8915 (10nM, 30mins). Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is Phospho-SMAD2 (Ser465/Ser467) (E8F3R) Rabbit mAb. Western blot analysis was performed using P-SMAD2 (Ser465/ Ser467) (E8F3R) Rabbit mAb. Mouse Anti-rabbit IgG (Conformation Specific) (L27A9) mAb (HRP Conjugate) #5127 was used for detection to avoid cross-reactivity with IgG.

    Chromatin immunoprecipitations were performed with cross-linked chromatin from HaCaT cells treated with Human Growth Factor β1 #8915 (7 ng/ml, 1 hr) and either Phospho-SMAD2 (Ser465/Ser467) (E8F3R) Rabbit mAb or Normal Rabbit IgG #2729 using SimpleChIP® Plus Enzymatic Chromatin IP Kit (Magnetic Beads) #9005. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human ID1 Promoter Primers #5139, Human JunB Promoter Primers, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
