This purified Mouse anti-ErbB-2 Monoclonal Antibody is specific to human, rat, and mouse ErbB2 (HER2). Over-expression of c-erbB-2 is observed in 15–40% of primary human breast tumors and correlates with poor prognosis in node positive breast cancer. Over-expression of c-erbB-2 is also observed in ovarian, gastric, salivary, and non-small cell lung carcinomas. Validated applications for mouse anti-ErbB-2 monoclonal antibody are immunoprecipitation, immunohistochemistry, flow cytometry, and Western blotting. Antibody Attributes: • Applications: Validated applications for Mouse anti-ErbB-2 monoc...

SKP2 (S-phase Kinase-associated Protein 2) belongs to the family of F-box proteins that interact with the Cyclin A-Cdk2 complex. In tumor tissues, SKP2 is expressed widely, such as colon mucinous carcinoma, gastric adenocarcinoma, breast cancer, melanoma, prostate adenocarcinoma, with particularly higher expression on lung adenocarcinoma, lung squamous carcinoma, squamous carcinoma of cervix, endometrial carcinoma, ovary serous carcinoma and leiomyosarcoma. A recent study suggests that SKP2 plays a role in oncogenesis and is involved in the pathogenesis of lymphomas. Positive tissue: Breast ca...

Molecular Probes® cholera toxin conjugates are made from a recombinant version of the B subunit only. This allows us to provide a very high-purity product that is completely free of the toxic A subunit. Cholera toxin B subunit (CT-B) attaches to cells by binding to ganglioside G M1 , making it a powerful tool for retrograde labeling of neurons. This tracer has been used in a variety of applications, including tracing of rat forebrain afferents, projections of the parabrachial region, and neurons of the urinary bladder wall. When used in neuronal tracing applications, CT-B is typically introduc...

EdU (5-ethynyl-2’-deoxyuridine) can be used as a replacement for BrdU (5-bromo-2’-deoxyuridine) and directly measures de novo DNA synthesis or S-phase synthesis of the cell cycle using click chemistry. Click chemistry is a method of covalently coupling an azide with an alkyne. Detection of EdU employs the copper(I) catalyzed click reaction with an azide modified fluorescent dye to form a stable triazole ring. Because of the small size of the click detection reagent, no harsh denaturation steps are needed to gain access to the DNA. Eliminating this step allows for more reproducible results, a s...
