Recombinant Anti-SOX2 antibody [EPR3131] (ab92494)

Transient Wnt and FGF signalling induce dual fated mouse neuromesodermal progenitors.

Immunostaining of cells treated with FGF/Wnt revealed the coexpression of Brachyury with Sox2 (NMPs). In the absence of Wnt, NPCs express Sox2 but the expression of Brachyury is only evident in a very small proportion of cells.

SOX2 immunostaining in sagittal maxillary incisor sections from E12 (A-D), E13 (E-H), E14 (I-L), and E15 (M-P) embryos.

At E13, strong SOX2 staining was seen in the lingual region of the epithelial dental lamina in all mice (E, G & H) except for the Usag-1^+/+/Runx2^-/- mice, in which SOX2 was found throughout the dental lamina (F). At E15, strong SOX2 staining was seen in the additional lingual bud in the Usag-1^+/+/Runx2^-/- mice (N).

Ab92494 staining SOX2 in the F9 (mouse embryonal carcinoma) cell line by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 4% PFA, permeabilized with 0.1% Triton-X. Samples were incubated with primary antibody (1/200). An Alexa Fluor^® 488-conjugated Goat anti-Rabbit IgG, Ab150077 (1/1000) was used as the secondary antibody. Counterstained with Ab7291 anti-Tubulin (1/1000), Ab150120 AlexaFluor^®594 Goat anti-Mouse secondary (1/1000). DAPI was used as a nuclear counter stain.

Negative control 1 Ab92494 was used as the primary antibody at 1/200 and Ab150120 was used as the secondary at 1/1000.

Negative control 2 Ab7291was used as the primary antibody at 1/1000 and Ab150077 was used as the secondary at 1/1000.
