Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (NBP3-32593) at 1/1,000 dilution was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.

Immunohistochemistry: Mesothelin Antibody (PSH02-30) [NBP3-32593]

Immunohistochemistry: Mesothelin Antibody (PSH02-30) [NBP3-32593] - Immunofluorescence analysis of paraffin-embedded human ovarian carcinoma tissue labeling Mesothelin with Rabbit anti-Mesothelin antibody (NBP3-32593) at 1/100 dilution.

The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 10% negative goat serum for 1 hour at room temperature, washed with PBS, and then probed with the primary antibody (NBP3-32593, green) at 1/100 dilution overnight at 4 ℃, washed with PBS. Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. Nuclei were counterstained with DAPI (blue).

Immunohistochemistry: Mesothelin Antibody (PSH02-30) [NBP3-32593]

Immunohistochemistry: Mesothelin Antibody (PSH02-30) [NBP3-32593] - Immunohistochemical analysis of paraffin-embedded human ovarian carcinoma tissue with Rabbit anti-Mesothelin antibody (NBP3-32593) at 1/1,000 dilution.

The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (NBP3-32593) at 1/1,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Immunocytochemistry/ Immunofluorescence: Mesothelin Antibody (PSH02-30) [NBP3-32593]

Immunocytochemistry/ Immunofluorescence: Mesothelin Antibody (PSH02-30) [NBP3-32593] - Immunocytochemistry analysis of NCI-H226 cells labeling Mesothelin with Rabbit anti-Mesothelin antibody (NBP3-32593) at 1/100 dilution.

Cells were fixed in 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 5 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Rabbit anti-Mesothelin antibody (NBP3-32593) at 1/100 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI.

Beta tubulin (red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594) was used as the secondary antibody at 1/1,000 dilution.

Background: Mesothelin

MSLN, also known as Mesothelin, has 4 isoforms, a 630 amino acid isoform that is 69 kDa, a 622 amino acid isoform that is 68 kDa, a 656 amino acid isoform that is 71 kDa, and a 621 amino acid isoform that is 68 kDa, expressed in lung, heart, placenta kidney, and overexpressed in mesotheliomas, ovarian cancers, and some squamous cell carcinomas. Membrane-anchored forms may play a role in cellular adhesion and megakaryocyte-potentiating factor (MPF) potentiates megakaryocyte colony formation in vitro. Current research is being performed on several diseases and disorders including squamous cell carcinoma, ovarian cancer, carcinoma, malignant biphasic mesothelioma, bile duct adenoma, malignant mesothelioma, malignant pleural mesothelioma, gastrointestinal stromal tumor, renal clear cell carcinoma, epithelioid sarcoma, benign mesothelioma, pancreatic ductal adenocarcinoma, asbestosis, pancreatic ductal carcinoma, thymic carcinoma, acute myeloid leukemia, epithelial ovarian cancer, myeloid leukemia, thoracic cancer, and pancreatitis. This protein has also shown an interaction with MUC16 and RSG1 in cell adhesion and pancreas development processes and pathways.
