It is desirable to visualize these events without interference from other regions deeper within the cell. Total internal reflection fluorescence (TIRF) microscopy utilizes an elegant optical sectioning approach to visualize fluorophores n

Here, we describe single-cell, single-molecule pull-down (sc-SiMPull), a TIRF microscopy-based coimmunoprecipitation method, to visualize thousands of individual proteins, their bindin

Matrixbeschreibung der Polarisation,the small GTPases Rho, Rac, and Cdc42, is one key mechanism that regulates cell polarity and migration during vertebrate gastrulation. In this chapter, we describe biochemical assays for detection of Wnt/Fz-mediated activation of Rho, Rac and Cdc42 in both mammalian cells and . embryo explants.

Interferenz an Mehrfachschichten,pendent biotinylation mediated by a promiscuous bacterial biotin ligase is a sensitive approach for evaluating protein interactions under physiological conditions. This technique allows for assessing protein association when conventional pull-down assays are not applicable due to high background or

Protein S-palmitoylation has been recently recognized as an important posttranslational modification involved in cell polarity, via dynamic covalent attachment of fatty acyl gr

In this chapter, we describe a protocol to detect secreted Wnt proteins in the culture medium of cell lines that ectopically or endogenously express Wnt genes. Th

Model systems such as zebrafish, whose in vivo development is accessible to both the microscope and genetic manipulation, are particularly well-suited to the use of live imaging. Here we describe

PCP is detected by the asymmetric distribution of core PCP proteins at different borders of epithelial cells. Believed to be critical for signaling,
