Invitrogen™ Podocalyxin Monoclonal Antibody (B34D1.3), PE, eBioscience™

Description

Description: The monoclonal antibody B34D1.3 recognizes human podocalyxin, a protein expressed on undifferentiated human embryonic stem cells (ES), embryonic carcinoma cells (EC), and embryonic germ cells (EG). Podocalxyin is a heavily glycosylated cell adhesion protein with homology to CD34 and endoglycan. It was first identified on kidney podocytes, and then found to be upregulated in a variety of human cancers such as breast and prostate cancer. Like other stem cell-specific markers, the epitope recognized by the B34D1.3 antibody is lost upon cell differentiation. The B34D1.3 antibody recognizes the ectodomain of podocalyxin, which is a different epitope from the Tra-1-60 and Tra-1-81 monoclonal antibodies. While Tra1-60 has been found to react with a sialidase-sensitive epitope, the epitope recognized by Tra1-81 has not been fully defined. Applications Reported: This B34D1.3 antibody has been reported for use in flow cytometric analysis. Applications Tested: This B34D1.3 antibody has been pre-titrated and tested by flow cytometric analysis of the NTERA cell line. This can be used at 5 μL (0.5 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 μm post-manufacturing filtered.

This gene encodes a member of the sialomucin protein family. The encoded protein was originally identified as an important component of glomerular podocytes. Podocytes are highly differentiated epithelial cells with interdigitating foot processes covering the outer aspect of the glomerular basement membrane. Other biological activities of the encoded protein include: binding in a membrane protein complex with Na+/H+ exchanger regulatory factor to intracellular cytoskeletal elements, playing a role in hematopoetic cell differentiation, and being expressed in vascular endothelium cells and binding to L-selectin.
