To transform the linear fluorescence intensity scale obtained with fluorescent microspheres to an antibody bound per cell (ABC) scale, a biological cell reference material is needed. Optimally, this material should have a reproducible and tight ABC value for the expression

Biological membranes are compartmentalized for functional diversity by a variety of specific protein-protein, protein-lipid, and lipid-lipid interactions. A subset of these are the preferential interactions between sterols, sphingolipids, and saturated aliphatic lipid tails responsible for liquid-liquid domain coexistence in eukaryotic

Angiogenic, that is, newly formed, blood vessels play an important role in tumor growth and metastasis and are a potential target for tumor treatment. In previous studies, the alpha(v)beta(3) integrin, which is strongly expressed in angiogenic vessels, has been used

X chromosome inactivation (XCI) is the mammalian mechanism that compensates for the difference in gene dosage between XX females and XY males. Genetic and epigenetic regulatory mechanisms induce transcriptional silencing of one X chromosome in female cells. In mouse embryos

PKC isoforms tau, alpha, and beta play fundamental roles in the activation of T cells and other immune cell functions. Here we show that the PKC inhibitor AEB071 both abolishes the production of several cytokines by activated human T cells
