Polypeptide surface marker for cells

摘要

This invention discloses a gene for the identification of cells comprising a selection leader segment, a cell marker segment and a transmembrane segment. The gene can be used to identify cells transfected with the gene by the steps of: inserting the gene having a selection leader segment, a cell marker segment and a transmembrane segment into the DNA or RNA of a cell, allowing the cell to express the gene, and detecting the expressed cell marker segment of the gene.
