Counterstains Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4338

Category: Cell Culture Protocols: Cell Staining Protocols

Counterstains are used to help differentiate the various cell types of subcellular structures seen in cell staining. They are essential for tissue sections, allowing the identification of the cell types, but also may be helpful in other staining reactions. - [Read Counterstains Protocol]

Histone H1 Kinase Activity Assay - http://www.bio.com/protocolstools/protocol.jhtml?id=p910

Category: Signalling Signal Transduction Protocols

This protocol describes assaying kinase activity of a putative kinase using Histone H1 as the substrate. Histone H1 is the canonical kinase substrate in this type of assay. Phosphorylation of Histone H1 is assessed by SDS-Polyacrylamide gel electrophoresis followed by autoradiography. Includes information: H1 Kinase Assay on Individual Xenopus Oocytes; H1 Kinase Assay on Xenopus Egg Extract Samples; H1 Kinase Assay on Tissue Culture Cells; Helpful protocol hints. - [Read Histone H1 Kinase Activity Assay]

Raf-1 Kinase Assay - http://www.bio.com/protocolstools/protocol.jhtml?id=p1980

Category: Signalling Signal Transduction Protocols: MAPK Protocols

This protocol uses mitogen-activated protein/ERK kinase (MEK) to activate the extracellular-signal-regulated (Erk) mitogen-activated protein (MAP) kinases upon agonist binding to receptors. Protocol includes information about: Harvest, Immunoprecipitation and Kinase Reaction. Also includes following solutions: Laemmli Sample Buffer (1X), ATP Mix, Kinase Buffer (10X), Lysis Buffer. Helpful protocol hints are also included. - [Read Raf-1 Kinase Assay]
