CloneR™ is a defined, serum-free supplement designed to increase the cloning efficiency and single-cell survival of human embryonic stem cells (ES cells) and induced pluripotent stem cells (iPS cells). CloneR™ enables the robust generation of clonal cell lines without single-cell adaptation, thus minimizing the risk of acquiring genetic abnormalities. CloneR™ is compatible with the TeSR™ family of media for human ES and iPS cell maintenance as well as your choice of cell culture matrix.For improved single-cell survival in additional applications, and higher cloning efficiency, try our CloneR™2 supplement (https://www.stemcell.com/products/cloner2.html).
