Form
Stella is a gene specifically expressed in primordial germ cells, oocytes, preimplantation embryos and pluripotent cells. It encodes a protein with a SAP-like domain and a splicing factor motif-like structure, suggesting possible roles in chromosomal organization or RNA processing. Embryos without Stella are compromised in preimplantation development and rarely reach the blastocyst stage. -

ICC/IF image of ab19878 stained mouse embryonic stem cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab19878, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

The image shows ab19878 staining of a crysosection of mouse embryonic genital ridges (E14.5). The samples were fixed overnight in 4% paraformaldehyde, permeabilised with 0.1% Triton and stained overnight at 4 degrees. 4µg/ml of antibody was used. Staining was in the nucleus and cytoplasm of Oct4-positive cells. The blue fluorescence is DAPI staining of DNA.

Predicted band size: 17 kDa
Observed band size: 23 kDa why is the actual band size different from the predicted?
Additional bands at: 125 kDa (possible non-specific binding)
Exposure time: 4 minutesThis blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% milk before being incubated with ab37113 overnight at 4°C. Antibody binding was detected using an anti-rabbit HRP secondary antibody, and visualised using ECL development solution ab133406.
