Biological Description

Alternative Names	APG4 autophagy 4 homolog C Antibody, APG4 C Antibody, Atg4c Antibody, AUTL1 Antibody, Autophagin 3 Antibody, Cysteine protease ATG4C Antibody
Research Areas	Cancer, Autophagy, Cardiovascular System
Cellular Localization	Cytoplasm
Accession Number	NP_116241.2
Gene ID	84938
Swiss Prot	Q96DT6
Scientific Background	ATG4C belongs to the peptidase C54 family. It is a cysteine protease required for the cytoplasm to vacuole transport (Cvt) and autophagy. Is not essential for autophagy development under normal conditions but is required for a proper autophagic response under stressful conditions such as prolonged starvation (By similarity). Cleaves the C-terminal amino acid of ATG8 family proteins MAP1LC3 and GABARAPL2, to reveal a C-terminal glycine. Exposure of the glycine at the C-terminus is essential for ATG8 proteins conjugation to phosphatidylethanolamine (PE) and insertion to membranes, which is necessary for autophagy. It also has an activity of delipidating enzyme for the PE-conjugated forms (1).

磷酸钠缓冲液的配制方法 123

高展远瞩2014-10-12

看了GE公司的NiSephrose6FastFlow说明书，说bindingbuffer建议20mMsodiumphosphate,0.5MNaCl,pH7.4,elutingbuffer中是在bindingbuffer中加了高浓度的咪唑，我想问一下，这个怎么配制啊？那个sodiumphosphate是什么？磷酸钠溶液？貌似不具有缓冲性，磷酸钠缓冲液？有可能，但是这个咋配啊？有我能想到的三个配制方法，想求助一下;
1.直接用固体磷酸钠配制成50mM的磷酸钠溶液，再调pH到7.4；（我们试着用这个做了下，发现挂不上柱）
2.配置磷酸钠盐缓冲液：按NaH2PO4：Na2HPO4以19：81的摩尔比配制成pH7.4的缓冲液？（附一张百度出来的配方
）

3.如果是磷酸钠盐缓冲液，可以直接将50mM的NaH2PO4的水溶液用NaOH调成pH7.4吗？
再者，2和3这两个方法配制的磷酸钠盐缓冲液有什么区别？最终效果是一样的吗？如果不一样，有什么理论的知识支撑呢？个人感觉是分析化学中酸碱理论中的缓冲液那里的知识。求帮忙解答这些疑问。
另外，我还想问一下，pH对于Ni柱对His-tagged的蛋白的分离纯化影响大吗？是怎么影响的？谢谢大家了！

缓冲物质更重要。
由弱酸及其盐、弱碱及其盐组成的混合溶液，能在一定程度上抵消、减轻外加强酸或强碱对溶液酸碱度的影响，从而保持溶液的pH值相对稳定。这种溶液称为缓冲溶液。

【求助】蛋白质酸碱性对离子交换色谱填料的选择蛋白质和糖学...123

ldx74226632009-08-05

求助：我目前需用离子交换法进行蛋白质的分离和纯化，但是我不知道要纯化的蛋白质的等电点，怎么样选择柱料及洗脱缓冲液呢？如果必须知道，有没有什么简便的方法测定蛋白质的等电点呢？谢谢

凝胶电泳缓冲液的配制123

haina1682021-07-23

我按下面方法配制电泳缓冲液：
Tris-base15.1g
甘氨酸94g
SDS5g
H2O1000ml
听人说就这样配制，PH值就会在8.3左右，都不要怎么调PH的，但不知我这样配制后PH值在6.4左右？迷惑，配制了几次还是这样。本人初次做sds-page，请前辈们指教。
另外Tris是以前师兄留下的，几年了已经，SDS也是以前的，但是没有开封，密封的很好。甘氨酸是新买进口封装的。会不会试剂过期的原因？

培养基高压蒸气灭菌后pH值的变化及其对细菌生长的影响123

mars7472005-08-25

:)
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?

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

一种缓冲溶液是一个共轭酸碱的混合物,那么为什么邻苯二甲酸氢钾、四硼 ...123

TWDAFRA01242017-10-03

缓冲溶液是含共轭酸碱对的，其中共轭酸与共轭碱都必须是弱酸或弱碱，这样才能组成缓冲液。因为邻苯二甲酸是弱酸，氨是弱碱，并且它们的同浓度的电离度相似，所以组成的缓冲溶液缓冲能力强。

药典中,纯化水酸碱度能用PH计测量吗?《中国药典》2020版讨论区...123

rainbow09282021-07-25

药典上说取本品10ml，加甲基红指示液（变色范围ph4.2-6.3，红~黄）2滴不得显红色；加溴麝香草酚蓝（变色范围ph6.0-7.6，黄~蓝）5滴不得显蓝色。
是否可以理解为纯化水得PH范围为6.3-7.6？能否直接用pH计测量？谢谢!
