The yeast three-hybrid system can be used to identify a protein partner of a known RNA sequence by screening a cDNA library fused to a transcription activation domain, with a hybrid RNA as 'bait.' Most commonly, such screens are performed to identify proteins that interact with a given RNA in vivo.

RNAseq is a relatively new tool for ecological genetics that offers researchers insight into changes in gene expression in response to a myriad of natural or experimental conditions. However, standard RNAseq methods (e.g., Illumina TruSeq® or NEBNext® ) can be cost prohibitive, especially when study designs require large sample sizes. Consequently, RNAseq is often underused as a method, or is a...

To our traditional library management, pursuing small and comprehensive library blindly or big and comprehensive one, which makes amounts of waste. In information society, people have varied requirements. To meet their requirements, library must positively develop more resources, positively organize the online Chinese information resources, provide effective online video service, greatly cultiv...

We report the application of individually addressable microelectrode arrays (MEAs) to study the heterogeneity of cell exocytosis at the subcellular level. Multiple subcellular-size electrodes are covered by a single PC12 cell for the investigation of subcellular exocytosis. PC12 cells have been seeded and cultured on top of three kinds of MEAs containing 16, 25, or 36 square microelectrodes (4 ...

We have constructed cDNA microarrays from the human testis large insert cDNA library, containing 9216 genes, together with several housekeeping genes. The cDNA microarrays were used to identify gene expression differences between human fetal and adult testes. Of >8700 hybridized clones, 731 exhibited significant differential expression characteristics. About 7500 genes were identified when the ...

We wish to identify genes associated with disease. To do so, we look for novel genes whose expression patterns mimic those of known disease-associated genes, a method we call Guilt-by-Association (GBA). GBA uses a combinatoric measure of association that provides superior results to those from correlation measures used in previous expression analyses. Using GBA, we have examined the expression ...
