Quick Overview for Recombinant Mesothelin antibody (ABIN7543156)

Target: Mesothelin (MSLN)

Antibody Type: Recombinant Antibody

Reactivity: Human

Host: Rabbit

Clonality: Chimeric

Conjugate: This Mesothelin antibody is un-conjugated

Application: ELISA, Western Blotting (WB), Immunohistochemistry (IHC), Immunofluorescence (IF), Surface Plasmon Resonance (SPR), Radioimmunoassay (RIA)

Clone: K1

Product Details anti-Mesothelin Antibody

Purpose: Anti-Mesothelin [K1], Rabbit IgG, kappa

Specificity: This antibody can bind the human mesothelium, expressed on many cancer cells like ovarian carcinoma.

Cross-Reactivity: Cynomolgus

Characteristics:

Original Species of Ab: Mouse

Original Format of Ab: IgG1

Purification: Protein A affinity purified

Immunogen: The original antibody was generated by immunization of mice with periodate-treated human ovarian cancinoma (OVCAR-3) cells. These mice had previously been made tolerant to normal human kidney membranes.

Isotype: IgG kappa

Application Details

Application Notes: This antibody was used for the study and characterization of CAK1 antigen present on ovarian cancers and normal mesothelium. The initial screening of the mesothelin reactive clones to live OVCAR-3 cells was done using immunofluorescence. Secondary screening was done using immunoperoxidase histochemistry on cryostat sections of normal human tissues and human tumors. Quantitative ELISA confirmed that K1 and OC125 antibodies bind to different epitopes on the OVCAR-3 cells (PMID: 1735605). This antibody can detect mesothelin in a western blot assay. Competition RIA was used to detect the presence of CAK1 antigen in the supernatent of protease or phosphatidylinositol-phospholipase C treated cells. An immunotoxin composed of K1 antibody and native Pseudomonas exotoxin was found to be selectively cytotoxic to cells expressing CAK1 antigen (PMID: 1727378). The affinity of K1 antibody to mesothelin was Kd= 8 nM and determined using surface plasmon resonance (BIAcore assay) (PMID: 9178820).

Comment:

This chimeric rabbit antibody was made using the variable domain sequences of the original Mouse IgG1 format, for improved compatibility with existing reagents, assays and techniques.
