Swiss Prot	Q13501
Scientific Background	SQSTM1 or Sequestome 1 (p62) is a ubiquitin binding protein that interacts with ubiqutin, providing a scaffold for several signaling proteins and triggering degradation of proteins throught the proteasome or lysossome. This gene regulates activation of the nuclear factor kappa-B (NF-kB) signaling pathway. The protein functions as a scaffolding/adaptor protein in concert with TNF receptor-associated factor 6 to mediate activation of NF-kB in response to upstream signals. Mutations in this gene result in sporadic and familial Paget disease of bone. SQSTM1 also binds autophagosomal membrane protein LC3/ATG8.

我在做一细菌不同酸碱度生长状况时,发现这些奇怪现象:pH=3的培养基灭菌(TSB液体培养基)灭菌后pH上升到到9.2!而原来pH=9.0的降到8.7(基本没多少变化),请问各位大侠,这是什么原因?

一般做不同酸碱度生长实验时,该如何才能防止pH在湿热灭菌后基本不变化?

氨取本品50ml，加碱性碘化汞钾试液2ml，放置15分钟；如显色，与氯化铵溶液（取氯化铵31.5mg，加无氨水适量使溶解并稀释成1000ml）1.5ml，加元氨水48ml与碱性碘化汞钾试液2ml制成的对照液比较，不得更深（0.00003%）。
二氧化碳取本品25ml，置50ml具塞量筒中，加氢氧化钙试液25ml，密塞振摇，放置，小时内不得发生浑浊。
易氧化物取本品100ml，加稀硫酸10ml，煮沸后，加高锰酸钾滴定液（0.02mol/L）0.10ml，再煮沸10分钟，粉红色不得完全消失。
不挥发物取本品100ml，置105℃恒重的蒸发皿中，在水浴上蒸干，并在105℃干燥至恒重，遗留残渣不得过1mg。
重金属取本品50ml，加水18.5ml，蒸发至20ml，放冷，加醋酸盐缓冲液（pH3.5）2ml与水适量使成25ml，加硫代乙酰胺试液2ml，摇匀，放置2分钟，与标准铅溶液1.5ml加水18.5ml用同一方法处理后的颜色比较，不得更深（0.00003%）。
微生物限度取本品，采用薄膜过滤法处理后，依法检查（附录ⅪJ），细菌、霉菌和酵母菌总数每1ml不得过100个。
【贮藏】密闭保存。
【化学成分】本品为蒸馏法、离子交换法、反渗透法或其他适宜的方法制得的供药用的水，不含任何附加剂。
【分子式与分子量】H2O18.02
【药理作用】溶剂、稀释剂

这里药典纯化水标准中并无PH值项目，请问对纯化水有PH值的要求吗，范围应在多少？请说明出处？
在纯化水检测中，检验酸碱度合格，但是发现PH在8左右。如果按以上标准检验合格，是否要考虑PH值？请知道的解答，谢谢！

酸碱滴定法中为什么要用缓冲溶液调节ph值123

如何选择缓冲溶液?_123

sweetwater2021-07-21

做试验的时候用到很多种缓冲液，Tris,triethanolamine,HEPES,还有磷酸缓冲液，不知道这些缓冲液之间有没有大的区别，选择缓冲液的依据是什么？

如果只是为了缓冲酸碱度，是不是可以用一种缓冲液来代替所有其他的？这样做试验就方便多了。谢谢指教

【求助】Whatman的DEAE52到底用不用酸碱预处理?怎么说法不一...123

langfeng2021-07-26

Whatman的网站上说DE52（货号4057-200）是预膨胀的（Preswollen），有的中文网站上说DE52是即用型。
这就是说不用酸碱预处理吗？
Whatman的网站上没有DE52最大耐受压力，请问又经验的战友应该是多少？

我是菜鸟,请教各位:强酸碱性样品可以用普通C18柱吗?谢谢了~ ...123

yandongliu2021-07-24

我的实验是考察药物不同PH值（水溶液，HCL和NaOH调PH值）下的稳定性情况等，PH从2-13。请问各位大侠：这种强酸性或强碱性水溶液样品可以直接进普通C18柱进行分析吗？
因为是考察不同PH对药物的影响，样品又不好改变其PH值，这种情况怎么办？希望有经验的高手指教。

我的流动相是甲醇-水（90：10）

谢谢赐教！

请进子版按格式发贴，自行修改，谢谢。

PH值在多少为碱性水?123

wuzhixuan20032005-06-13

25倍电转缓冲液的ph＝8.3真的不能调吗？听师兄说一次配好液后它的ph值就必须是8.3，不能再进行加酸或加碱调节，可我配了一天也没达到这个要求，用的是18g甘氨酸和3.64g的trisbase加dd水到100ml，总是ph值到8.8左右，在配过程中可以加热吗，不然太难溶解了，
