you are waiting for the knock out mice. It can easily take up to 1 year
before you have enough mice to perform your experiment. Also make sure that
the gene hasn't been knocked out by others. It would save you a lot of time if you can get the mice somebody already made. |

The onset of wrinkles, muscle wasting and cataracts has been delayed and

It was done by "flushing out" retired cells that had stopped dividing. They
accumulate naturally with age.
The scientists believe their findings could eventually "really have an
impact" in the care of the elderly.
Experts said the results were "fascinating", but should be taken with a bit

腹腔注射,小分子,最终会扩散达到平衡吧?

(b) adult mice injected ip with tamoxifen (2 mg) for 5 days,
(c) adult mice injected ip with tamoxifen (2 mg) for 10 days,
and (d) adult mice injected ip with tamoxifen (4 mg) for 10 days.
都远远高过 1 uM
对斑马鱼胚胎做小分子处理用10-15 uM 很常见。
按照我的估算,和老鼠里 1-3mg/kg 大体相当。

一組觀察樣本只要老鼠推桿子十次,就把飼料投進籠子裡。老鼠很快地就發現推桿子的
次數和飼料有固定的關連。
而第二組樣本則是不固定的隨機投放飼料,有可能推三次就投飼料,也有可能推50次才
投,老鼠也很快的發現推桿子與飼料有關連,但是卻無法找到其關聯模式。
在這裡問大家一個問題,請問您覺得哪一個籠子的老鼠會持續不斷的推桿子?
答案是第二組。行為科學家發現,老鼠會因為希望重現吃到飼料的驚喜,而持續不斷的
推桿子。甚至即便飼料已經掉很多了,老鼠還是不願意停。反而是推固定次數就有飼料
的老鼠,也許嘗試兩三次吃到飼料之後就會停下來,等餓了再去推。
