Anti-Sox2 (Thr-128), Phosphospecific Antibody

Our Sox2 (Thr-128) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects chicken, human, mouse, rat, and Xenopus Sox2 (Thr-128) and is antigen affinity purified. It is great for use in WB, ICC.

Western blot of mouse F9 stem cells untreated (lanes 1 & 3) and treated with lambda phosphatase (lanes 2 & 4). The blot was probed with mouse monoclonal Sox2 antibody (lanes 1 & 2) and rabbit polyclonal Sox2 (Thr-128) phospho-specific antibody (lanes 3 & 4).

Immunocytochemical labeling of phosphorylated Sox2 in aldehyde fixed and NP-40 permeabilized human NCI-H446 lung carcinoma cells. The cells were labeled with rabbit polyclonal anti-Sox2 (Thr-128) phospho-specific (SP0381). The antibody was detected using goat anti-rabbit Ig:DyLight® 594.

Western blot of mouse F9 stem cells untreated (lanes 1 & 3) and treated with lambda phosphatase (lanes 2 & 4). The blot was probed with mouse monoclonal Sox2 antibody (lanes 1 & 2) and rabbit polyclonal Sox2 (Thr-128) phospho-specific antibody (lanes 3 & 4).

Target

Sox2 (Thr-128)

Scientific Background

Embryonic stem cells can maintain a pluripotent state that is controlled by a set of transcription factors that include Oct-4, Sox2, and Nanog. Chromatin immunoprecipitation experiments show that Sox2 and Oct-4 bind to thousands of gene regulatory sites, many of which regulate cell pluripotency and early embryonic development. siRNA knockdown of either Sox2 or Oct-4 results in loss of pluripotency, while overexpression of Oct-4 and Sox2, along with additional transcription factors Klf4 and c-Myc, can reprogram somatic cells to a pluripotent state. Sox2 also regulates adult multipotent progenitors in various epithelial tissues, and may be important for survival and regeneration of these tissues. The activity of Sox2 may be regulated by phosphorylation and methylation. Akt1 phosphorylates Thr-118 and enhances Sox2 transcriptional activity, while Set7 can monomethylate Lys-119 leading to inhibition of Sox2 transcriptional activity, as well as Sox2 ubiquination and degradation. In addition, Sox2 Thr-128 is constituitively phoshorylated in the F9 mouse stem cell line.

Molecular Weight

Immunogen

Phospho-Sox2 (Thr-128) synthetic peptide (coupled to carrier) corresponding to amino acids surrounding Thr-128 in mouse Sox2. This site is identical in human Sox2 (Thr-126), and has some homology with the conserved site in mouse Sox1 (Ser-136) and Sox3 (Ser-154).

Immunogen Species

Mouse

Species Reactivity

Chicken, Frog, Human, Mouse, Rat

Storage

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Physical State

Liquid

Buffer

PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol

Dilution Ranges

WB: 1:1000
ICC: 1:100

Conjugate

Unconjugated

Specificity

The antibody was cross adsorbed to unphosphorylated Sox2 (Thr-128) peptide before affinity purification using phospho-Sox2 (Thr-128) peptide. This antibody detects a 34 kDa* protein on SDS-PAGE immunoblots of mouse F9 stem cells. This reactivity is not observed after lambda phosphatase dephosphorylation of Sox2.
