Description :Rabbit Polyclonal Antibody

Species :

Tag :

Expression System:

Sequence :

Specificity :Recognizes the human SMAD2 protein

Cited Applications :ELISA, IP, WB
Ideal working dilutions for each application should be empirically determined by the investigator.

Cross Reactivity :Human, Mouse and Rat

Host Isotype / Clone# :Rabbit, IgG

Immunogen :The antibody was produced against synthesized peptide corresponding to an internal region of human SMAD2 protein.

Purification :Affinity chromatography

Stability :1yr at –20oC from date of shipment

Sample Data :Western blot using affinity purified Anti-SMAD2 (1:2,500 dilution) to detect over-expressed Smad2 in COS cells (arrow). Lane C shows mock infection of COS cells with lentiviral vector alone. Lane S2 shows detection of Smad2 in lysates of COS transfected with Smad2. Lane V contains lysates of MDA-MB231 cells treated with vehicle; the next lane contains lysates of MDA-MB231 cells treated with TGFβ.

Scientific Background :SMADs are essential intracellular components for the signal transduction of TGFβ family members. SMAD2 is an intracellular mediator of TGFβ family and activin type 1 receptor (1). SMAD2 mediate TGFβ signaling to regulate cell growth and differentiation. SMAD2 is released from cytoplasmic retention by TGFβ receptor-mediated phosphorylation. The phosphorylated SMAD2 then forms a heterodimeric complex with SMAD4, and this complex translocates from cytoplasm into nucleus. By interacting with DNA-binding proteins, SMAD2 complexes then positively or negatively regulate the transcription of target genes. Inactivating mutations in SMAD2 have been found in various cancers (2).
