Anticuerpo anti-antígeno embrionario específico de estadio-4, clon MC-813-70

As the focus of stem cell research undergoes a transition from animal to human models, researchers are in critical need of validated products to support the isolation, maintenance, differentiation, and characterization of human stem cells. While many reagents designed for rodent systems can be applied to human stem cell studies, they are not truly optimized for robust human stem cell culture or analysis. This is why human stem cell researchers have always trusted EMD Millipore, the first provider of commercially available human embryonic stem cells and human neural stem cell lines, to accelerate their research. All of our human stem cell systems are extensively tested in defined media culture, and differentiated progeny are comprehensively characterized with highly validated antibodies and detection reagents.

Millipore’s new STEMCCA lentivirus reprogramming kits make it easier than ever to generate induced pluripotent stem (iPS) cells. Unlike traditional iPS generation which requires simultaneous co-infection by four separate expression vectors, the STEMCCA kits use a single polycistronic lentiviral vector to improve efficiency and reduce the number of viral integrations. The STEMCCA vector is comprised of the transcription factors Oct-4, Klf4, SOX-2, and c-Myc (OKSM), separated by the self-cleaving 2A peptide and IRES sequences 1,2. It is also available with flanking LoxP sites incorporated for Cre-mediated excision of the exogenous reprogramming transgenes. STEMCCA Vector Advantages: (1) Efficient: uses a single vector with four transcription factors rather than co-transducing four separate expression vectors (2) Minimizes viral integrations: single vector reduces the risks of insertional mutagenesis and viral reactivation and (3) Excisable: Cre/LoxP-regulated version enables removal of reprogramming transgenes.
