The 100-page “Stem Cell Catalog 2006” from Chemicon International presents items for stem cell culture and pluripotent and multipotent stem cell research. Among them are numerous stem cell lines, ES-cell optimized media, characterization and detection kits, and a variety of stem-cell-specific antibodies and growth factors. The downloadable document details methylation and telomerase detection kits, markers of early differentiation and cell signaling pathways, and products for neural, hematopoietic and endothelial progenitor stem cell research. Substrates for cell culture, and vectors and transfection kits for gene targeting also are specified. References, case studies and technical information are provided.
