An Effective Method for Raising Antisera Against β-defensins: Double-copy Protein Expression of mBin1b in E. coli

Defensins are a family of evolutionarily relatedvertebrate antimicrobial peptides with a characteristicβ-sheet-rich fold and a framework of six disulphide-linkedcysteines. The two main defensin subfamilies, α- andβ-defensin, differ in the length of pep…     

Statures in Han populations of China

<正>Dear Editor,Shortly after initiating the"Physical Anthropological Research on Han Chinese"research project,we applied uniform sampling methods as well as methods and instruments of measurement to obtain a complete set of measurements of physical anthropological indicators among Han populations across China.Among these measurements,body stature was a key indicator.Currently,there should be reliable     

建立多重液相基因芯片方法快速检测狐狸、水貂成分

基于xMAP液相芯片新型生物技术平台,分别以狐狸线粒体DNA D-loop区序列、水貂线粒体DNA细胞色素b基因序列为模板设计特异扩增引物和探针,并对探针进行锁核酸修饰,建立了二重xMAP液相基因芯片方法,用于快速检测狐狸和水貂源性成分。该法能准确鉴定鉴别狐狸和水貂DNA,对其他18种动物物种DNA均呈检测阴性,对狐狸、水貂DNA的检测低限分别为2. 8pg/μl、0. 9pg/μl,对肉类混样检出限为0. 05%(m/m)。对目标源性DNA含量为1%(V/V)的32份饲料与食品核酸添加样本均呈对应目标检测阳性。结果表明,该方法特异性强、灵敏度高,适用于食品与饲料领域相关原料和产品的质量与安全检验。

棉花根醇提物与水提物的止咳祛痰抗炎作用研究

制备棉花根醇提物和水提物,止咳实验采用小鼠浓氨水引咳法,祛痰实验采用气管酚红排泌法,抗炎实验采用二甲苯致耳肿胀法,观察棉花根醇提物和水提物的止咳祛痰抗炎作用。实验小鼠分正常对照组,醇提物与水提物高低剂量组及阳性药物对照组。结果发现棉花根醇提物、水提物均能延长小鼠的咳嗽潜伏期,减少咳嗽次数,均能增加气管内的酚红排泌量,对二甲苯所致的耳肿胀均有显著的抑制作用。
