Time-resolved fluorometric assay for the detection of endostatin in chromatographically separated extracts of natural peptides

We present a heterogeneous non-competitive immunological detection assay for peptide and protein antigens from crude extracts of biological sources. This time-resolved fluoroimmunoassay (TR-FIA) has been designed in a solid-phase mode using 96-well microtiter plates. Using the rare-earth metal europium as a fluorescent marker, a highly sensitive, selective and efficient procedure was developed. This technique prevents from interferences of intrinsic protein fluorescence which is highly important for antigen measurement in complex matrices. The TR-FIA has been applied for the detection of circulating forms of the potential anti-tumor agent endostatin, a C-terminal fragment of collagen XVIII, and its close homolog collagen XV (restin) from hemofiltrate. Endostatin was detected with a limit of detection of 3 ng (150 fmol/well) and a broad dynamic range from 10-1000 ng/well.     

A versatile shuttle cosmid vector for the efficient construction of genomic libraries and for the cloning of fungal genes

A shuttle cosmid vector, pANsCos1, has been constructed for Escherichia coli and filamentous fungi. This vector contains two cos sequences separated by a single XbaI restriction site. pANsCos1 allows the efficient construction of representative genomic libraries from as little as 15–20 g of genomic DNA. Due to the presence of a functional hygromycin B phosphotransferase gene (hph) transformation of fungal protoplasts with pANsCos1, or derivatives of it, results in the formation of hygromycin B-resistant transformants. The T7 and T3 RNA polymerase promoter sequences flanking the cloning site, in combination with two adjacent NotI sites facilitate genomic walking and the rapid construction of restriction maps of cloned inserts.Dedicated to Professor Dr. K.

以馆藏资源助力地域文化符号搭建文旅融合底蕴平台

地域文化符号是地方历史文化发展的载体,也是地域文明的象征。图书馆作为地域信息及文献资源的收藏地,在地域文化发展中起着至关重要的作用,在当前经济社会发展的背景下,也是文旅融合发展的重要组成部分。本文以图书馆助力地域文化符号搭建文旅融合底蕴平台为出发点,通过分析找准地域文化符号的意义和方法,探究图书馆在充分利用馆藏资源的基础上,找准文旅融合的契合点,厚积地域文化底蕴的方式和路径,通过进一步融合现代发展元素,打造文化旅游特色品牌项目,使文旅产业成为带动地域经济发展的"动力产业"。     

Profiling celiac disease antibody repertoire

The aim of this study was to dissect the autoantibody response in celiac disease (CD) that remains largely unknown, with the goal of identifying the disease-specific autoantigenic protein pattern or the so called epitome. Sera from CD patients were used to select immunoreactive antigens from a cDNA phage-display library. Candidate genes were identified, the corresponding proteins produced and their immunoreactivity validated with sera from CD patients and controls. Thirteen CD-specific antigens were identified and further validated by protein microarray. The specificity for 6 of these antigens was confirmed by ELISA. Furthermore we showed that this antibody response was not abolished on a gluten free diet and was not shared with other autoimmune diseases. These antigens appear to be CD specific and independent of gluten induction. The utility of this panel extends beyond its diagnostic value and it may drive the attention to new targets for unbiased screens in autoimmunity research.
