Provider: Invitrogen Antibodies
Product name: CD326 (EpCAM) Monoclonal Antibody (1B7), eFluor™ 660, eBioscience™
Antibody type: Monoclonal
Antigen: Other
Description: Description: EpCAM (Epithelial cell adhesion molecule, CD326, KSA, TROP1) is a 40 kD cell-surface adhesion molecule participating in homophilic, calcium-independent cell-cell interactions. EpCAM is a type-I transmembrane protein, and is expressed primarily on the basolateral surface of most epithelia. Although normal epithelia express low levels of EpCAM, increased expression has been correlated with increased proliferation and progression to a mesenchymal phenotype. EpCAM has also been used as a diagnostic marker on circulating metastatic carcinoma cells, while cancer cells of non-epithelial origin do not express EpCAM. Applications Reported: This 1B7 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 1B7 antibody has been pre-titrated and tested by flow cytometric analysis of human A549 cell line. This can be used at 5 µL (0.06 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. eFluor® 660 is a replacement for Alexa Fluor® 647. eFluor® 660 emits at 659 nm and is excited with the red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome. Excitation: 633-647 nm; Emission: 668 nm; Laser: Red Laser. Filtration: 0.2 µm post-manufacturing filtered.
Reactivity: Human
Host: Mouse

Experimental details: Figure 1 Multiparametric flow cytometry of PBMCs capturing uPAR/int beta1 CTC subsets. Breast cancer PBMCs were first sorted applying gating parameters to select for DAPI - (4', 6-diamidino-2-phenylindole)/EpCAM - /CD45 - /CD44 + /CD24 - cells. Cells were then subsequently sorted to obtain uPAR/int beta1 subsets containing combinatorial expression of these markers. Antibodies used for flow cytometry and cell sorting were: anti-human CD45-APC-Cy7 (Biolegend, cat # 304015, 1:50 dilution), mouse anti-human EpCAM-PE CD326 (eBiosciences, cat # 12-9326-71, 1:40 dilution), anti-human CD24-PE ML5 (Biolegend, cat # 311106, 1:20 dilution), anti-human CD44-PE-Cy7 IM7 (Biolegend, cat # 103030, 1:20 dilution), mouse anti-human uPAR (CD87)-FITC (AbD Serotec cat # MCA2506FT, 1:10 dilution), anti-human int beta1 (CD29)-ApC TS2/16 (Biolegend, cat # 3030008, 1:50 dilution). Cells were confirmed to be CTCs by performing RT-PCR, immunoflurescence and genotyping arrays. Representative images are shown.

Experimental details: Figure 8 Elevated IL-17RB expression in cancer cells derived from tumor-draining lymph nodes in breast cancer patients correlates with aggressive growth nature A Freshly collected human breast cancer (hBC) specimens (PT, primary tumors; LN, paired LN metastasis from the same breast cancer patient) were digested with collagenase-containing buffer overnight. Depletion of hematopoietic cells by CD45 Dynabeads (Invitrogen) enriched the EpCAM + cells for following xenografts. Percentages of EpCAM + cells in human primary breast cancer cells were confirmed by FACS analysis (left two panels: before enrichment; right two panels: after enrichment). All of the histograms were shown that they were EpCAM expressing (black line), compared to isotype control (gray filled). B Tumorigenesis assay was determined in NOD/SCID/IL2Rgamma mice orthotopically injected with hBC PT and hBC LN cells. Representative data on day 180 were shown. White arrow: Orthotopic injection site. C Dot plot illustrated the tumor volumes of hBC PT and hBC LN cell-injected NOD/SCID/IL2Rgamma mice on day 180 ( n = 11). All tumors were confirmed by pan-keratin IHC staining of fat pad sections. D, E H&E stainings and IHC stainings of pan-keratin were shown in the representative cases of fat pad sections from (B). Scale bar: 1 mm (left panels), 100 mum (right panels). F IHC stainings of IL-17RB were shown in the representative cases of fat pad sections from (B). Scale bar: 10 mum. G The correlatio
