Mesothelin Antibody / MSLN

SKU: orb606569

Description

Mesothelin is a 40kDa glycosyl-phosphatidylinositol-anchored glycoprotein cleaved from a 69kDa precursor protein. Mesothelin immunoreactivity is high in cancers of the ovary (serous papillary, endometrioid and undifferentiated) and pancreas, with less frequent staining seen in adenocarcinomas of the endometrium, lung and stomach/esophagus. Mesothelin is one of the most sensitive markers for mesothelioma.

Images & Validation

• Tested Applications: IHC-P
• Dilution range: Immunohistochemistry (FFPE): 1-2ug/ml for 30 min at RT
• Reactivity: Human, Mouse, Rat
• Application Notes:
  Optimal dilution of the MSLN antibody should be determined by the researcher.

Key Properties

• Antibody Type: Primary Antibody

Analysis of HuProt (TM) microarray containing more than 19, 000 full-length human proteins using Mesothelin antibody (clone MSLN/2131). These results demonstrate the foremost specificity of the MSLN/2131 mAb. Z- and S- score: The Z-score represents the strength of a signal that an antibody (in combination with a fluorescently-tagged anti-IgG secondary Ab) produces when binding to a particular protein on the HuProt (TM) array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If the targets on the HuProt (TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-scores. The S-score therefore represents the relative target specificity of an Ab to its intended target.
