Immunohistochemical assessment of 5-bromo-2-deoxyuridine (BrdU) in tissue sections is a widely used method to evaluate cell proliferation in vivo. However, this method requires time-consuming preparation of paraffin sections and laborious counting of BrdU-labeled nuclei on multiple sections. Here, we report the development of a rapid and reliable method to quantitate BrdU incorporation in intes...

The molecular profiles of protein expression from hundreds of cell lysates can be determined in a high-throughput manner by using fluorescent bead technologies, enzyme-linked immunosorbent assays (ELISAs), and protein microarrays. Although powerful, these tools are costly and technically challenging and thus have limited accessibility for many research groups. We propose a modification of tradi...

We report a comparative evaluation of three different laboratory methods for screening large numbers of mouthwash DNA samples for common cystic fibrosis mutations. Sensitivity, specificity, and costs of ARMS (allele refractory mutation detection system), dot blotting, and a deletion/digest/PAGE method (multiplex PCR of exons 10 and 11, digest with HincII followed by polyacrylamide gel electroph...

The gene encoding the capsid protein of Macrobrachium rosenbergii nodavirus (MrNV) was cloned into pGEX-6P-1 expression vector and then transformed into the Escherichia coli strain BL21. After induction, capsid protein-glutathione-S-transferase (GST-MrNV; 64 kDa) was produced. The recombinant protein was separated using SDS-PAGE, excised from the gel, electro-eluted and then used for immunizati...

conclusions over-expression of the synthetic cpc/β protein in the bacterial system (escherichia coli bl-21) showed that e. coli can be used as a basis for further research to produce this desired protein in large quantities. results the sds-page analysis and dot blotting confirmed the production of recombinant c-pc/β in the bacterial expression system. over-expression of cpcb gene was optimized...
