That is good. What is your concentration of CHX? you can try 100ug/ml,
although most protocol say around 50ug/ml
What is the concentration of your gradient, w/v or w/w? 15-45% w/w gradient
and 15-50% w/v gradient work good.
How did you make the gradient? Usually, a gradient marker (machine)
generates highest quality and most reproducible gradients. If no such
equipment available, you can use freeze-thaw method to make gradient.
Specifically, lay heaviest, in you case 40%, in to the bottom, put ... 阅读全帖 |

If we only count the difficulty, double helix is really one of the "lightest"

If we compare the impact on science, double helix can in no way be compared
with quantum mechanics or relativity, even with field theory and renormalization
Its impact is mostly limited to biochemistry and has little impact on other
areas.(Not to say those breakthroughs in mathematics)

graduation year. With CK or step 1 failure, even AMGs have great trouble
matching into their ideal programs. Step 3 failure penalty is the lightest,
followed by CS. If I were you, I would focus on inside connection or great
LORs from big cows. So-so LORs+CK failure+long GY almost amount to no

探索星系的捷径
A Shortcut to Galaxy Exploration
1. 问苍天情为何物？
1. Ask what love is heaven?
有人类的历史以来，人类就不断地探索自然，扩展了解自然的疆界。哥伦布发现新大陆
就是最好的例子。人类探索自然的勇气是从哪儿来的呢？来自人类情感的力量。那么，
情感是什么东西呢？这是千万年来，文学家探索的主题。在有一些文学家的眼中，物理
学家是没有情感的冷血动物。我就是一个物理学家。但是，我一点也不埋怨这些文学家
。虽然物理学家在自然界的探索中做出了伟大的贡献，但是，物理学家从来就没有给出
情感的物理定义是什么，也没有找到自然界蕴含情感的丝毫证据。所以，虽然人类知道
自己的生存发展跟自然环境是密不可分的，但是，很少有人类表达出对自然环境感谢的
情感。在很多人的眼中，自然界是死亡无情的物质世界。中国有一句古语，叫做“天若
有情天亦老”。因为几乎所有人类相信天是不老的，所以，认为苍天是没有情感的，就
不足为奇了。我提出了一个宇宙生长衰老的模型。虽然这个模型及其简单，能解释大多

we know there's pi^{0} and pi^{\pm}, pi^{0} doesn't have anti-particle. So
it should be a unit representation of SU(3), cause under SU(3) transform-
ation it remains unchanged. Similiarly, pi^{\pm} obey SU(2) flavor symmtry
