The type II cAMP-dependent protein kinase (PKA) is localized in certain cellular compartments through association with specific A-kinase anchoring proteins (AKAPs). A variety of blotting and electrophoresis techniques have been developed to study the protein-protein interactions that occur between the regulatory (R) subunit of PKA and AKAPs. These methods have also been used for a variety of pu...

Extracellular vesicles (EVs) are released by mammalian cells and are thought to be important mediators of intercellular communication. There are many methods for isolating EVs from cell culture media, but the most popular methods involve purification based on ultracentrifugation . Here, we provide a detailed protocol for isolating EVs by differential ultracentrifugation and analyzing EV protein...

A rapid and easy procedure for preparing Northern blots is described. RNA is denatured with glyoxal in the presence of ethidium bromide and glycerol, then electrophoresed through agarose in a buffer that does not require recirculation. Without any additional washes, the RNA is vacuum-blotted to a nylon membrane in NaOH, which simultaneously removes the glyoxal adducts. All of these steps plus p...

Background and Aims: Herpes simplex virus type 1 (HSV1) remains a potentially serious health problem world wide. All infected people, including asymptomatic ones, are potential sources for virus transmission. Virus envelope contains at least 13 glycoproteins, which glycoprotein D is the major target of immune responses. The aim of this study was development of a specific method that is a more...
