Accession # Q811S9

Specificity

Detects human, mouse, rat Nucleostemin in direct ELISAs and Western blots. In direct ELISAs, less than 1% cross-reactivity with recombinant rat Nucleostemin C-terminal peptide (aa 281-538) is observed. Rat Nucleostemin specific IgG was purified by first passing the sera over a rat Nucleostemin aa 2-538 column and then passing the bound fraction over a rat Nucleostemin aa 281-538 column to removed rat Nucleostemin C-terminal specific IgG.

Scientific Data Images for Nucleostemin Antibody

Detection of Human Nucleostemin antibody by Western Blot.

Detection of Human Nucleostemin by Western Blot.

Western blot shows lysates of PC-3 human prostate cancer cell line and SW480 human colorectal adenocarcinoma cell line. PVDF membrane was probed with 0.25 µg/mL of Goat Anti-Human/Mouse/Rat Nucleostemin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1638) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for Nucleostemin at approximately 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Nucleostemin antibody in U2OS Human Cell Line by Immunocytochemistry (ICC).

Nucleostemin in U2OS Human Cell Line.

Nucleostemin was detected in immersion fixed U2OS human osteosarcoma cell line using 10 µg/mL Goat Anti-Human/Mouse/Rat Nucleostemin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1638) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red, upper panel; Catalog # NL001) and counterstained with DAPI (blue, lower panel).

Detection of Human Nucleostemin antibody by Simple WesternTM.

Detection of Human Nucleostemin by Simple WesternTM.

Simple Western lane view shows lysates of PC-3 human prostate cancer cell line, loaded at 0.2 mg/mL. A specific band was detected for Nucleostemin at approximately 83 kDa (as indicated) using 5 µg/mL of Goat Anti-Human/Mouse/Rat Nucleostemin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1638) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.
Detection of Human Nucleostemin by Immunocytochemistry/Immunofluorescence

Detection of Human Nucleostemin by Immunocytochemistry/Immunofluorescence

Embryonic stem cell markers. Immunohistochemistry: A. NANOG; B. OCT4. The majority of nuclei in the NANOG IHC are brown indicating the presence of NANOG. Some, but not all, nuclei are positive for OCT4. Negative (secondary antibody only) and positive (seminoma) controls are presented in the thumbnails below the photomicrographs. C. Immunofluorescence against nucleostemin. Left: anti-nucleostemin antibody, center: DAPI, right: merge. Bar = 10 microns.

Background: Nucleostemin

Nucleostemin is a protein found in the nucleoli of embryonic stem cells, adult CNS stem cells, primitive cells in the bone marrow and cancer cells. It is not in the differentiated cells of most adult tissues. It has been suggested to play a role in controlling the cell-cycle progression in stem cells and cancer cells (1-3).
