Abstract

Monoclonal antibodies (mAbs) of the IgG1 isotype obtained to the full-length recombinant pneumolysin (rPly) did not recognize or poorly recognized conformational epitopes of native pneumolysin in ELISA. At the same time, polyclonal antibodies (pAbs(rPly)) detected native pneumolysin in sandwich ELISA when they were used as capture and detecting antibodies simultaneously. All mAbs(rPly) inhibited erythrocyte hemolysis induced by native pneumolysin. The combined use of mAbs(rPly) did not reveal an increase in optical density in ELISA and an increase in inhibition hemolytic activity, which suggests that mAbs(rPly) are directed to the same or spatially closely located epitopes. pAbs(rPly) more effectively inhibited erythrocyte hemolysis than mAbs(rPly).

重组型溶血素单克隆抗体的免疫化学特性及功能活性。
在ELISA中获得的IgG1同型单克隆抗体(mab)不识别或不识别天然溶气素的构象表位。同时,夹心ELISA法检测多克隆抗体(pAbs(rPly))作为捕获抗体和检测抗体同时使用时,可检测到天然溶血素。所有单克隆抗体(rPly)均抑制天然溶气血素诱导的红细胞溶血。联合使用单克隆抗体(rPly)在ELISA中没有显示出光密度的增加和抑制溶血活性的增加,这表明单克隆抗体(rPly)是针对相同或空间上紧密定位的表位。pAbs(rPly)比mAbs(rPly)更有效地抑制红细胞溶血。

期刊介绍: Bulletin of Experimental Biology and Medicine presents original peer reviewed research papers and brief reports on priority new research results in physiology, biochemistry, biophysics, pharmacology, immunology, microbiology, genetics, oncology, etc. Novel trends in science are covered in new sections of the journal - Biogerontology and Human Ecology - that first appeared in 2005. World scientific interest in stem cells prompted inclusion into Bulletin of Experimental Biology and Medicine a quarterly scientific journal Cell Technologies in Biology and Medicine (a new Russian Academy of Medical Sciences publication since 2005). It publishes only original papers from the leading research institutions on molecular biology of stem and progenitor cells, stem cell as the basis of gene therapy, molecular language of cell-to-cell communication, cytokines, chemokines, growth and other factors, pilot projects on clinical use of stem and progenitor cells. The Russian Volume Year is published in English from April.
