查询词典 S

Nucleoprotein is also a major immunogenetic antigen for SARS; however, several tests have shown that N protein had the reactivity with other coronavirus positive sera. It is therefore an advantage of S protein as recombinant target antigen for SARS serum diagnosis compared with recombinant N protein. Moreover, S protein has been shown to be the major antigenic determinant that induces neutralizing antibodies and protective immunity to SARS-CoV, so it is also important in designing SARS genetic engineering vaccine.

SARS-CoV S 蛋白由1255 个氨基酸组成，体外表达如此大的蛋白很困难，而且表达蛋白的可溶性不高；其次，实验已经证实，全长S 蛋白含有大量无关的表位，致使表达的全长S蛋白对SARS 阳性血清的检出率低于S 蛋白片段；另外作为疫苗研究，S 蛋白上大量无关表位作为异体蛋白进入体内，会引发机体的过度免疫反应，这也是SARS-CoV 可能的致病机理之一。

Sulfur isotope measurements of deposits such as those in the 1.1 Ga Duluth Complex, the Per-mo-Triassic intrusions of the Noril'sk area, and the 1.4 Ga Kabanga intrusions provide evidence for the derivation of S from both sulfide-and sulfate-bearing country rocks. The 1.3 Ga Voisey's Bay deposit provides an example where δ^34 S values of the ores commonly fall within the accepted mantle range of 0±2‰, but detailed studies of Proterozoic metasedimentary country rocks show that their weighted average δ^34 S value is also within this range.

In the study, a set of near isogenic lines of CMS-S, S-Mo17Rf3Rf3 and S-Mo17rf3rf3, were adopted, and TdT-mediated dUTP nick-end labeling, in situ immunolocalization of cytochrome c and DNA ladder assay were employed to study the programmed cell death process on cytology and DNA level. The microscope observation evidenced that tapetal cells of fertile anthers kept intact until microspores, and then were disintegrated on later developmental stage.
