Product Summary for Smad1 [p Ser206] Antibody

Immunogen

This affinity purified Smad1 [p Ser206] Antibody was prepared from whole rabbit serum produced by repeated immunizations with a phosphorylated synthetic peptide corresponding to the region of amino acids containing serine 206 of human Smad1 protein. (Uniprot: Q15797)

Reactivity Notes

A BLAST analysis was used to suggest 100% cross reactivity with Smad1 from human, Duckbill platypus, Drosophila, mouse, opossum, chimpanzee, bonobo, orangutan, gorilla, macaque, cattle, sheep, pig, rat, horse, salmon, chicken, and dog based on the sequence homology with the immunogen. Reactivity against homologues from other sources is not known.

Modification

p Ser206

Specificity

This affinity-purified antibody is directed against the phosphorylated form of human Smad1 protein at the pS206 residue. The resultant affinity purified antibody was then cross adsorbed against the non-phosphorylated form of the immunizing peptide. Reactivity occurs against human Smad1 pS206 protein and the antibody is specific for the phosphorylated form of the protein. Reactivity with non-phosphorylated human Smad1 is minimal by ELISA and western blot.

Description

This affinity-purified antibody is directed against the phosphorylated form of human SMAD1 protein at the [p Ser206] residue. The product was affinity purified from monospecific antiserum by immunoaffinity purification. Antiserum was first purified against the phosphorylated form of the immunizing peptide. The resultant affinity purified antibody was then cross adsorbed against the non-phosphorylated form of the immunizing peptide

Store vial at -20C prior to opening. Aliquot contents and freeze at -20C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4C as an undiluted liquid. Dilute only prior to immediate use.

Scientific Data Images for Smad1 [p Ser206] Antibody

Western Blot: Smad1 [p Ser206] Antibody [NBP1-77858]

Western Blot: Smad1 [p Ser206] Antibody [NBP1-77858]

Western Blot: Smad1 [p Ser206] Antibody [NBP1-77858] - Shows detection of endogenous phosphorylated SMAD1 in whole cell lysates from human hepatoma (HEPG2, lanes 1-4) derived cell lines treated with PBS, BMP2 (5 ug/ml), EGF and reacted for 1 hour at room temperature. Primary antibody was pre-incubated before reaction with blot as follows: top row - with PBS, middle row - with the immunizing phosphorylated peptide and bottom row - with control or non-phosphorylated peptide. The membrane was washed and reacted with a 1:3,000 dilution HRP-conjugated a-Rabbit IgG for 1 hour at room temperature. Detection was by ECL.

Applications for Smad1 [p Ser206] Antibody

Application
Recommended Usage

ELISA

1:5000-1:25000

Western Blot

1:500-1:2000
Application Notes
This affinity purified antibody has been tested for use in ELISA and by western blot. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 52 kDa in size corresponding to phosphorylated SMAD1 protein by western blotting in the appropriate stimulated tissue or cell lysate or extract. This antibody is specific for the phosphorylated pS206 of SMAD1. Stimulation of EGF, TGFbeta BMP2, and 0.5M NaCl are recommended for 1 hour.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: Smad1

SMAD1 is also known Mothers Against Decapentaplegic homolog 1, Mothers against DPP homolog 1, hSMAD-3, JV4-1, Transforming growth factor-Beta-Signaling Protein 1 or BSP1. SMAD proteins are signal transducers and transcriptional modulators that mediate multiple signaling pathways. SMAD1, as a transcriptional modulator, is activated by BMP (Bone Morphogenetic Protein) type 1 receptor kinase (it is a receptor-regulated SMAD or R-SMAD). BMPs are involved in a range of biological activities including cell growth, apoptosis, morphogenesis, development and immune responses. SMAD proteins have been implicated as downstream effectors of TGF beta/BMP signaling. In response to BMP ligands, SMAD1 can be phosphorylated (other sites besides the most prominent of S206, are S187, S195, and S214). S-206 is phosphorylated by ERK in response to mitogenic growth factors, or by recombinant ERK in vitro; this can be tested by treating cells with EGF or in cancer cells where Ras is activated. The phosphorylated form of this protein forms a complex with SMAD4, which is important for its function in the transcription regulation. This protein is also a target for SMAD-specific E3 ubiquitin ligases, such as SMURF1 and SMURF2, and undergoes ubiquitination and proteasome-mediated degradation.
