Image intensification techniques for detection of proteins in cultured cells.

abstract：:In this chapter we have detailed a method that can be generalized to link virtually any DNA substrate to a chromatography matrix at its ends via an avidin-biotin linkage. We have used this technique to construct a left-handed Z-DNA column for the purpose of identification and purification of Z-DNA-binding proteins. Th...

abstract：:Embryonic stem (ES) cells are cells derived from the inner cell mass of a blastocyst stage embryo. These self-renewing multipotent cells are able to differentiate to the three embryonic germ layers, the endoderm, ectoderm, and mesoderm, and are thus able to produce virtually all cell types. The ES cell capacity to gen...
