Human embryonic stem cell methods and PODXL expression
First Claim
1. A kit comprising an antibody that specifically binds PODXL on the surface of a cell, and which is cytotoxic to said cell, and an agent that detects a human embryonic stem cell marker, wherein the antibody comprises(a) at least one light chain variable region comprising the following complementarity determining regions (CDRs):

Abstract
A method of identifying an undifferentiated human embryonic stem cell in a sample which may contain such cells, the method comprising identifying the cell or cells within the sample that express podocalyxin-like protein (PODXL) on their surface. A method of isolating an undifferentiated human embryonic stem cell from a sample containing such cells, the method comprising isolating the cell or cells within the sample that express PODXL on their surface. Typically, the methods use an antibody which binds to PODXL. Undifferentiated human embryonic stem cells isolated by the method may be useful in cell therapy. Also, in particular, compositions of cells differentiated from a human embryonic stem cell but which composition has been depleted of undifferentiated human embryonic stem cells are provided which are useful in cell therapy.
