We present a simple molecular indexing method for quantitative targeted RNA sequencing, in which mRNAs of interest are selectively captured from complex cDNA libraries and sequenced to determine their absolute concentrations. cDNA fragments are individually labeled so that each molecule can be tracked from the original sample through the library preparation and sequencing process. Multiple copi...
The genes of top athletes are a valuable genetic resource for the human race, and could be exploited to identify novel genes related to sports ability, as well as other functions. We analyzed the expressed sequence tags from top half-pipe snowboarding athletes using the SMART complementary DNA (cDNA) library construction method to elucidate the characteristics of the athlete genome and the diff...
An estimated 100,000 genes lie on our 46 chromosomes. One third of these are thought to be specifically expressed in our brains at different periods over the course of our lives. Over the past few years, a small but growing number of genes have been cloned. Mutations in a number of these genes lead to a disruption of the normal CNS developm ent . The ability to isolate genes is probably one of ...
Full-length cDNAs play an essential role in identifying genes and determining their promoter regions. Here we describe a simple method for constructing a full-length cDNA library, which has the following advantages: (i) it consists of only three steps including direct ligation between a vector and a cDNA strand using T4 RNA ligase, (ii) it contains neither a PCR process generating mutations nor...
A sensitive immunoassay was used to identify recombinant plasmids carrying cDNA fragments of bovine caseins in the cDNA library from bovine mammary gland mRNA. Colonies grown on nitrocellulose filters were lysed in situ and proteins from the lysates were blotted onto CNBr-activated cellulose filter paper. Antigens covalently bound to CNBr-activated paper or bound to nitrocellulose filters were ...
To isolate cDNA clones of low-abundance mRNAs expressed in monkey cerebral cortex but absent from cerebellum, we developed an improved subtractive cDNA cloning procedure that requires only modest quantities of mRNA. Plasmid DNA from a monkey cerebellum cDNA library was hybridized in large excess to radiolabeled monkey cortex cDNA in a phenol emulsion-enhanced reaction. The unhybridized cortex c...
Here, we describe the application of a RecA-based cloning technology to generate full-length cDNA libraries enriched for genes that are differentially expressed between tumor and normal tissue samples. First, we show that the RecA-based method can be used to enrich cDNA libraries for several target genes in a single reaction. Then, we demonstrate that this method can be extended to enrich a cDN...
Several groups have isolated cDNA clones encoding different thyroid hormone binding proteins, although in each case only one type of cDNA was characterized for a given tissue (1-5). We have found three different cDNAs in libraries prepared from mouse skeletal muscle tissue at different stages of development and from the mouse C2 muscle cell line. Two different probes were used to screen these l...
