GTPÎ³S-Induced Inhibition of cAMP Binding to the cAMP Receptor (cAR1) in Dictyostelium Discoideum - http://www.bio.com/protocolstools/protocol.jhtml?id=p1175

Category: Signalling Signal Transduction Protocols

This protocol assays inhibition of in vivo binding of [3H]-cAMP to cAR1 by GTPÎ³S. Dictyostelium discoideum respond to extracellular cAMP through the cAMP chemoattractant receptor (cAR1). Binding of cAMP to the G protein-coupled cAR1 is inhibited by the GTP analog GTPÎ³S. Protocol includes information on: Solutions used, BioReagents and Chemicals and Protocol Hints. - [Read GTPÎ³S-Induced Inhibition of cAMP Binding to the cAMP Receptor (cAR1) in Dictyostelium Discoideum]

Category: Signalling Signal Transduction Protocols: Chemokine Protocols

Under-Agarose assay is a useful method for observing the response of a cell population to one or more chemoattractant sources. BioProtocol - [Read The Under-Agarose Migration Assay]

TransWell Chemotaxis Protocol. - http://bioprotocol.bio.com/protocolstools/protocol.jhtml?id=p2156

Category: Immunology: Chemotaxis

TransWell Chemotaxis protocol. trans-well chemotaxis method from bioprotocol. The protocol is a method for studying migration towards a concentration gradient of chemoattractant of leukocytes (neutrophils, monocytes and lymphocytes) or other migratory cells. An upper chamber containing a suspension of cells is separated by a membrane from a lower chamber containing medium with chemoattractant. Chemotaxis of the cells from the upper chamber into the lower chamber can be quantified. - [Read TransWell Chemotaxis Protocol.]
