An Improved Method For Transferring Nucleic Acids To Nylon Membranes, Bruce D. Parker
An Improved Method For Transferring Nucleic Acids To Nylon Membranes, Bruce D. Parker
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Methods currently in use for the separation and identification of specific segments of nucleic acids involve long transfer periods or elaborate apparatuses and result in the production of a single blot. Contamination by organisms or enzymes is always a factor to be dealt with. An improved method for transferring nucleic acids from acrylamide or agarose gels for use in hybridization has been developed. This method uses NaOH as the blotting medium to improve the rate and efficiency of transfer to nylon membranes. As many as six blots can be obtained within one hour using this method. This method is effective …

A recent study showed that cAMP analogs lowered cAMP levels in rat hepatocytes. The present work demonstrates that cAMP analogs also lowered cAMP in a rapid, concentration-dependent manner in heart and fat cells. In order to determine if the cAMP-dependent protein kinase mediated this effect, techniques were developed to assay the protein kinase activity ratio in hepatocytes treated with cAMP analogs. The activation of protein kinase and phosphorylase in hepatocytes by 8-pClΦS-cAMP (where 8-pClΦS- indicates 8-parachlorothiophenyl-) was concentration-dependent and occurred in parallel to proportionate decreases in cAMP. More than 20% of the cAMP binding sites on the protein kinase were …
