目的制备人高迁移率非组蛋白N2(HMGN2)多克隆抗体,并用于HMGN2的亚细胞定位分析。方法提取人淋巴因子激活的杀伤细胞(LAK)总RNA,应用RT-PCR从其总RNA中分离HMGN2cDNA,以pGEX-1λT为载体,构建HMGN2基因大肠杆菌表达载体。应用GST亲合层析柱分离GST-HMGN2融合蛋白,将此融合蛋白免疫新西兰兔,获得抗血清经正辛酸-硫酸铵分步沉淀法初步纯化。用ELISA法检测HMGN2抗体,免疫细胞化学染色法分析HMGN2的亚细胞分布。结果经酶切产物电泳分析和DNA序列测定证明成功构建出HMGN2基因重组原核表达载体pGEX-1λT-HMGN2。转化大肠杆菌经异丙基-b-D-硫代半乳糖苷(IPTG)诱导后获得相对分子质量约35×103的GST-HMGN2融合蛋白。该融合蛋白免疫所得免疫血清经ELISA检测显示获得滴度为1∶2000的较高效价的兔抗人HMGN2多克隆抗体。并应用此抗体对THP-1细胞进行的免疫细胞化学染色显示,经LPS刺激后除细胞核外,胞浆亦明显着色。而且用ELISA法在细胞培养液亦检测到HMGN2。结论本实验成功制备出HMGN2特异多克隆抗体,免疫细胞化学分析初步证明在LPS刺激下HMGN2不仅分布于单核吞噬细胞核,还分布于细胞浆,并可释放到细胞外。

为探讨人子宫颈黏液的抗菌机制,采用酸性尿素聚丙烯酰胺凝胶电泳和反相高压液相色谱技术,从人子宫颈黏液酸溶性提取物鉴定出对大肠杆菌氨苄青霉素耐药株ML-35p有较强的抗菌活性的多肽HCP-21和HCP-26.蛋白质N端氨基酸序列测定和精确质谱分子质量测定证明,HCP-21为HMGN2,HCP-26为SLPI片段.提取原代培养宫颈上皮细胞的总RNA,采用RT-PCR技术扩增出一条与HMGN2 cDNA大小相同(270bp)目的基因片段,表明在生理状况下,宫颈上皮细胞即可表达其mRNA.制备HMGN2多克隆抗体,对生理状态下宫颈组织切片和宫颈黏液涂片进行HMGN2分子免疫组化分析表明,该分子主要分布于子宫颈黏膜层,并存在于子宫颈黏液.HMGN2分子在宫颈黏膜上皮组织和黏液中固有表达,可能在子宫颈天然免疫防御中起重要作用.

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.
