Mouse Monoclonal Antibody
Brand: Affymetrix eBioscience 14-5768-82
Additional Details : Weight : 0.01000kg
Description: The hog.2 antibody recognizes human og, a homeobox transcription factor expressed in embryonic stem cells (ESC). og is essential for self-renewal of ESC and the inner cell mass and is throught to function in the same capacity as other factors such as Oct4 and Sox2. og plays a crucial role in embryonic cell fate specification following formation of the blastocyst by regulating proliferation and preventing differentiation. og functions by directly binding DNA consensus sequences to activate or repress transcription. In differentiating ESC, og binds to its own promoter leading to repression of expression. og has been reported to be overexpressed in germ cell tumors of the gonads and central nervous system as well as breast and colorectal cancer. Applications Reported: This hog.2 antibody has been reported for use in western blotting, immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, and immunocytochemistry. Applications Tested: This hog.2 antibody has been tested by immunoblotting of NTERA cell lysates and can be used at less than or equal to 1 μg/mL. The hog.2 antibody has been tested by immunohistochemistry of formalin-fixed paraffin embedded tissue using high or low pH antigen retrieval and can be used at less than or equal to 20 μg/mL. The hog.2 antibody has been tested by immunocytochemistry on formaldehyde fixed and permeabilized cells and can be used at less than or equal to 5 μg/mL.It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 μm post-manufacturing filtered. NANOG (og homeobox) is a divergent homeodomain protein that directs pluripotency and differentiation of undifferentiated embryonic stem cells. NANOG mRNA is present in pluripotent mouse and human cell lines, and absent from differentiated cells. Human NANOG protein shares 52% overall amino acid identity with the mouse protein, and 85% identity in the homeodomain. Human NANOG maps to gene locus 12p13.31, while the mouse NANOG maps to gene loci 6 F2. Murine embryonic NANOG expression is detected in the inner cell mass of the blastocyst. Research studies have shown that high levels of human NANOG expression in the undifferentiated N-Tera embryonal carcinoma cell line. Further, NANOG is a transcription regulator involved in inner cell mass and embryonic stem (ES) cells proliferation and self-renewal. The role of NANOG 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 (also known as Oct-4), another germline-specific transcription factor, and the transcription factors Sox2, Klf4 and Lin28 along with c-Myc in mouse fibroblasts. Experiments have demonstrated that iPS cells could be generated using expression plasmids expressing NANOG, 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. When overexpressed, NANOG promotes cells to enter into S phase and proliferation. Diseases associated with dysfunction in the NANOG protein include tetracarcinoma and germ cell/embryonal cancer.
