Anti epcam antibody

Manufactured by Miltenyi Biotec

The Anti-EpCAM antibody is a laboratory tool used to detect the presence of the Epithelial Cell Adhesion Molecule (EpCAM) protein in biological samples. EpCAM is a cell surface protein that is expressed on epithelial cells and some cancer cells. The Anti-EpCAM antibody can be used to identify and isolate cells expressing EpCAM for research purposes.

After the gradient test, the mononuclear cells were incubated with 100 μl of micromagnetic beads coated with anti-EpCAM antibody (Miltenyi-Biotec) and 100 μl of FcR-blocking reagent (Miltenyi-Biotec) for 30 minutes at 4°C and then incubated with 20 μl of magnetic beads coated with anti-CD45 antibody (Miltenyi-Biotec) for 15 minutes at 4°C. The mixture was passed through a magnet-filled column with an AutoMACSPro cell separator system (Miltenyi-Biotec) using the positive selection protocol (POSSELD program) to enrich for EpCAM-positive cells and the negative selection protocol (DEPLETE program) to enrich for CD45-depleted CTCs. The CD45-depleted (i.e., CD45-negative) fraction underwent an additional run through the magnet-filled column using the MACS DEPLETES program to prevent any residual contamination of CD45-positive cells.

Isolation of Hepatic Oval Cells from DDC-treated Mice

Mice were fed with 0.1% DDC (Sigma-Aldrich, St. Louis, MO) for 3 weeks to induce the activation of OCs. OCs were isolated as we previously reported [26 (link)]. Briefly, livers were perfused from portal vein with collagenase and pronase digestion. Liver cells were resuspended and centrifuged for collection of NPCs. NPCs were centrifuged through a discontinuous gradient of 20% and 50% PercollTM (Amersham Biosciences, Pittsburgh, PA). Finally, OCs were isolated from these cells fragment using a MiniMACS column containing anti-EpCAM antibody (Miltenyl Biotec, Auburn, CA). The EpCAM+ cells were tested for OC markers by flow cytometry and determined to contain OCs at approximately 95% purity. Cells were cultured on type I collagen coated dishes (BD Biosciences, San Jose, CA) in complete medium. Single clones were isolated and expanded in vitro.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
