我的皮肤: 刚读完大学的时候脸上不停地长痘痘,大概过了2年终于停了..现在夏天皮肤
是混合偏油或油性,冬天是偏干,总之很难侍候. 而且皮肤有时容易敏感,对大多数的
sunscreen和粉底/BB cream/ting moisturizer要么觉得很油,要么发痒或长痘.

1. Shiseido skincare purifying cleanser. 这个是我用过最最最好的cleanser,洗得
非常干净,有很细很细的磨砂,适合每天晚上用,早上用的话可能就嫌干一点.少量就气泡

每一种air purifier都有适用多大空间的说明。
放多少,就看你家的空间了。
便宜和贵的主要区别在于,做工,寿命,安静程度,和 filter的功效。
你可以去看看review就知道了。
但是对于那些说可以lifetime reuse filter的 purifier还是回避比较好。

30 nt primer and gene specific(GS) primer. Then they use close to adapter 3
'-end nested primer and another nested GS primer.
After the nested PCR, I sometimes still see multiple bands. I have to gel-
purify the PCR products with correct size and sometimes to repeat 2nd PCR to
amplify it before cloning.
One suggestion is to purify mRNA for RACE, which gives you mu... 阅读全帖

来自主题: Biology版 - 问个phusion和TA cloning
需要用pGEM T-easy这个vector,
pcr是用phusion做的,得到的是blunt end,
问一下3'端加A,
我是直接在PCR reaction里加一点taq呢(看thermo网站说加A前纯化很重要。。。)?
还是说purify以后再用taq,72度20分钟(这一步还要纯化吗?还是直接可以往下做?
)。
我上次用了purified的和taq一起,然后纯化了,然后TA,结果没连上,都是载体自连
。。。
请有经验的说说。
谢谢~~

Doesn't matter. Use pure GST to deplete anti-GST antibody, or use protein
with another tag to purify specific antibody.
20kd protein could be GST only, typical with purified GST-fusion protein.

来自主题: Biology版 - 哪位TX做过 Single site mutant?
Design primers F/R to cover you gene, then design primers F1/R1 with the
single site mutation to cover the mutation area. Do PCR1 with F/R1, PCR2
with F1/R, then purify the two products, put them in the third PCR tube as
template, with F/R as the primer, do the third PCR, purify the product, and
then clone into your target vector. Done!
