Flow assays offer visualization of cell adhesion under wall shear stress. Visualization of the different events of cell adhesion can be quantified by selective image acquisition and subsequent image processing. Flow assays are suited for adhesive events which occur very rapidly in a time scale shorter than that of most static adhesion assays. Also, events subsequent to the initial events can be studied such as cell stabilization and spreading giving some insight into the kinetics of cell-cell. - [Read Dynamic Flow Assay for Cell Adhesion in a Parallel Plate Flow Chamber]
Flow assays allow visualization of cell adhesion under well-defined wall shear stress. Visualization of the events of cell adhesion are quantified by selective image acquisition and image processing. Events subsequent to the initial events can be studied such as cell stabilization and spreading. John T.

Fixation is to preserve cells and tissue constituents in as close a life-like state as possible and to allow them to undergo further preparative procedures without change. Fixation arrests autolysis and bacterial decomposition and stabilises the cellular and tissue constituents so that they withstand the subsequent stages of tissue processing. Great detailed guide with protocols. Anthony S-Y Leong. - [Read Fixation and Fixatives - A great guide]

Protocol outlines the general procedure and requirements for in vitro translation of CFTR and outlines some assays using in vitro translated product. Core glycosylation of CFTR occurs in the ER. An assay for this processing step requires the
addition of microsomal membranes to the basic in vitro translation mixture. This protocol takes this into account. - [Read In vitro Translation Assays for CFTR]
Protocol describes the acquisition and processing of confocal
fluorescent and bright field images of live cells, expressing cyan fluorescent protein(CFP) and/or yellow fluorescent protein (YFP), with a spinning disk confocal head on a Zeiss Axiovert 200 M microscope.
