    • 摘要: 2-DE is the most commonly used technology to separate hundreds of proteins from the plant tissues.We analyzed and studied the processes of sample preparation,IFE,second-phase electrophoresis,gel-staining.The result showed that the sample preparation due to different elements (CHAPS,Triton X-100,DTT etc)should be selected according to different pyrolysis liquid elements.Longer of gel requires more loading amount of sample (5 times loading amount of sample in G250-stainning more than silver-stainning).Higher isoelectric focusing voltage the longer is the process of focusing.The volume fraction of SDS-PAGE is 10%—15%,commonly used 12%.polyacrylamide gel.The second -phase electrophoresis should select constant current and firstly 10 mA /gel should be set to run 0.5—1.0 h then 30 mA /gel till second-phase electrophoresis was finished.%双向电泳技术是目前最常用的能够从植物组织中分离出上千种蛋白的技术.因此,需对蛋白样品制备过程、等电聚焦、第二相电泳、染色等进行分析探讨,结果表明,样品制备需根据样品的成分选择不同的裂解液成分(如:CHAPS,Triton X-100和 DTT 等);胶条越长要求上样量越大(考染上样量约为银染上样的5倍),等电聚焦电压越大,聚焦过程也越长;SDS-PAGE 胶体积分数为10%~15%,常用12%;第二相电泳需选择恒定电流,且先以10 mA /胶,跑0.5~1.0 h,再以大电流30 mA /胶至第二相电泳完成.

    • 摘要: 通过蛋白组学技术研究生物体最终的执行功能是后基因组时代的重点之一。目前,双向电泳因成本低、分离效果好仍然是蛋白组学研究的一项经典技术。为了得到高质量的双向电泳图谱,首先需制备出蛋白含量高、杂质少、稳定性好的植物样品。因此,结合植物蛋白提取的原理和方法,对蛋白制备结果影响较大的细胞破碎、预分级、杂质去除、裂解液配置以及对蛋白的溶解等几方面提出了针对性的建议。%It is one of the key focus in the post genome era that the final executive function of biology is studied through proteomics technolo-gy.At present,the two-dimensional electrophoresis is still a classic technology of proteomics research because of its low cost and good separa-tion effect.In order to get high quality map of two-dimensional electrophoresis,it is necessary to produce good plant samples with high protein content,less impurity and good stability.Combining the principle and method of plant protein extraction,we put forward the targeted suggestions that influence the result of the protein preparation,such as cell crushing,grading,impurity removal,lysis buffer content and so on.

    • 摘要: 应用单链构象多态性(SSCP)方法研究榨菜低盐腌制条件下的微生物群落结构与变化.研究了凝胶质量浓度、电泳前处理、银染操作条件对SSCP分析方法的影响.结果表明,在凝胶质量浓度为22 g/dL、丙烯酰胺与双丙烯酰胺质量比为29:1,并加入体积分数6%的甘油,4°C条件下1×TBE缓冲液中250 V电泳18 h,通过强碱性显影液和甲醛作还原剂的银染方法显色,可以获得理想的SSCP图谱.对榨菜低盐腌制不同时期样品的SSCP图谱分析结果,发现在榨菜腌制初期优势菌群为肠膜明串珠菌(Leuconostoc mesenteroides),随后转变为植物乳杆菌(Lactobacillus plantarum)和短乳杆菌(Lactobacillus brevis)占优势;腌制后期主要存在的优势菌群为植物乳杆菌和Lactobacillus versmoldensis,结合感官分析证实这些优势乳酸菌对保持制品高品质具有功能作用.%Microbial community and its changes in pickled mustard tuber were investigated at the low salinity by using single-strand conformation polymorphism (SSCP) method. Effects of gel concentration, glycerol addition, foretreatment of electrophoresis and silver s taining methods on SSCP pattern were also examined in this manuscript. The results demonstrated that an ideal SSCP method was obtained as the optimum conditions, gel concentration of 22 g/dL at the crosslinking degree of 29: 1 (a ratio of acrylamide and bisacrylamide), glycerol concentration of 6%, voltage of 250 V, electrophoresis buffer of 1×TBE, electrophoresis at 4 C for 18 hours,and using silver staining method of strong alkaline solution and formaldehyde as reducing agent.Based on the optimized SSCP method for pickled leaching liquid measurement, it was found that the Leuconostoc mesenteroides is the dominant microorganism in the initial stage of pickling, then Lactobacillus plantarum and Lactobacillus brevis grown up with the alteration of environmental conditions. At the later stage, the dominant microorganism are Lactobacillus plantarum and Lactobacillus versmoldensis, respectively. The contribution of lactic acid bacteria was confirmed by microbial community structure analysis in pickled mustard tuber with low-salinity, which is carried out by combining the sensory evaluation method.
