OCT4 Antibody (MA1-104) in ICC/IF
Immunofluorescence analysis of Oct4/Pou5F1 was done on 70% confluent log phase NTREA-2 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Oct4/Pou5F1 (9B7) Mouse Monoclonal Antibody (Product # MA1-104) at 2 µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product #...

Product Specific Information
MA1-104 detects Oct4/Pou5F1 in Human embryonic carcinomic samples, but not in adult samples (e.g. HeLa cells). This antibody did not show reactivity in a mouse embryonic cell line (i.e. F9 embryonic carcinoma cells).
MA1-104 has been successfully used in FACS, IF, and WB. By Western blot, this antibody detects a band at 40 kDa in human NCCIT and NTERA-2 embryonal carcinoma cells, but not in negative control cells.
Target Information
POU5F1, also commonly known as Oct-4, is a maternally expressed octamer-binding protein that was the first transcription factor described for the early stages of development. The role of POU5F1 in embryonic development suggested that it might be useful in the creation of stem cells that might be useful in cell replacement therapies in the treatment of several degenerative diseases. Artificial stem cells, termed induced pluripotent stem (iPS) cells, can be created by expressing POU5F1 and the transcription factors Sox2, Klf4 and Lin28 along with c-Myc in mouse fibroblasts. More recently, experiments have demonstrated that iPS cells could be generated using expression plasmids expressing POU5F1, Sox2, KlfF4 and c-Myc, eliminating the need for virus introduction, thereby addressing a safety concern for potential use of iPS cells in regenerative medicine.
