The manganese-containing superoxide dismutase (MnSOD) is a major component of the cellular defence mechanisms against the toxic effects of the superoxide radical. Within the framework of studies on anti-oxidant enzymes and their protective role in the human parasitic nematode Onchocerca volvulus, sequences encoding the MnSOD were isolated and examined in this study. Degenerate primers were desi...

Suppression subtractive hybridization (SSH) is a widely used method for separating DNA molecules that distinguish two closely related DNA samples. Two of the main SSH applications are cDNA subtraction and genomic DNA subtraction. In fact, SSH is one of the most powerful and popular methods for generating subtracted cDNA or genomic DNA libraries. The SSH method is based on a suppression PCR effe...

tree nuts, including almond (prunus dulcis) are a source of food allergens often associated with life-threatening allergic reactions in susceptible individuals. although the proteins in almonds have been biochemically characterized, relatively little has been reported regarding the identity of the allergens involved in almond sensitivity. the present study was undertaken to identify the allerge...

Hu sheep is one of the most important species in China; it is also listed as one of the 78 nationally protected domestic animals by the Chinese government in 2000. The construction of cDNA expression library of Hu sheep is of great significance for protecting individual genomes, generating transgenic sheep, and conducting clinical research using cDNA from Hu sheep. In this study, the total RNA ...

Backgrounds and Aims: Coxsakievirus B3 (CVB3), one of the six Coxsakievirus B serotypes, is a member of the Enterovirus genus within the Picornaviridae family. CVB3 is an important pathogen of viral myocarditis, which accounts for more than 50% of viral myocarditis cases. The genome of CVB3, like that of other Entroviruses, is a single-stranded, sense, polyadenylated RNA molecule with 7400 nucl...

A cDNA with 2.3 kb encoding F1-F0 ATP synthase (proton ATPase) beta-subunit homologue was isolated from a testis cDNA library of the sea urchin, Hemicentrotus pulcherrimus. The deduced amino acid sequence consisted of 523 residues which contained a 19-residue amino-terminal signal peptide and a 8-residue glycine-rich consensus sequences. Analysis of poly(A) +RNA and/or total RNA from H. pulcher...

Total RNA from wheat spikes infected with F. graminearum Fg2 was extracted and the mRNA was purified. Switching Mechanism at 5' end of the RNA Transcript (SMART) technique and CDS Ill/3' primer were used for first-strand cDNA synthesis using reverse transcriptase by RT-PCR. Primer extension polymerase chain reaction was used to construct the double-strand cDNA that was digested by proteinase K,...
