在pH=10含有酒石酸盐(A)的氨性缓冲液中, 用0.020 mol/L EDTA 滴定同浓度的Pb2+。已知lgK(PbY)=18.0, 化学计量点时lgaY(H)=0.5, lgaPb(OH)=2.7, lgaPb(A)=2.8 (Pb2+与A 形成1:1络合物)。则化学计量点时 lgK'(PbY)=___。(注:1、保留一位有效数字;2、答案的字体为Times New Roman)如何...
不用PBS也不用Hanks洗,只要把旧培养液吸的干净一点,直接加酶消化应该不会有什么问题。弃培养液后,用0.04%的EDTA冲洗一次,再用1/4v的0.04%的EDTA室温孵育5min,弃取大部分EDTA,加入与剩余EDTA等量的胰酶(预热)总体积1/10v。消化到有细胞脱落。不过有人说EDTA对细胞不好,有证据吗?培养的BASMC:倒掉旧培养液加入...

TIMES STAFF WRITER NEW YORK — Robert MacNeil confirmed Monday that he will retire as co-anchor of PBS’ “MacNeil/Lehrer NewsHour” next year and said his decision was influenced by funding difficulties in public television. MacNeil, 63, told “NewsHour” staffers that he intends to leave ...
从4月份起,中国中药面临着在欧盟全面退市的风险,10万从业人员可能因此失业。 欧盟是世界上最大的植物药市场,年销售额上百亿欧元。7年前欧盟出台《传统植物药注册程序令》,要求曾以食品、保健品、甚至农副土特产品名义进口的所有中草药生产企业必须在2011年3月31号前达到注册标准,才能留在欧盟市场。但因为申请注册...
