g*****n 发帖数: 241 | 1 我替我们系的一个朋友问个问题,他想在zebrafish的上皮细胞特异性的表达GFP,但他
不研究zebrafish,所以不知道该到哪里找相关的zebrafish的promoter的资料。请研究
zebrafish的同僚帮忙指点一下。
谢谢 |

x***m 发帖数: 184 | 2 最近也对zebrafish感兴趣,可惜周围都没有实验室可以交流。
请问现在大家用zebrafish做模式生物的研究热点有那些? 较之于其它vertebrate模式
生物如frog, chicken和mice有那些特别的优势呢, 除了比较透明?
美国有哪些做zebrafish的好实验室? |
|
x***m 发帖数: 184 | 3 为什么在frog和chicken里面做genetic screen但在zebrafish里可以呢? 记得很多年前
就读到过用EMS突变老鼠进行genetics screen啊.
记得zebrafish也有genome duplication, 所以在downregulate gene expression上很
依赖morpholino. |
|
s******y 发帖数: 137 | 4 其实从transgenetic 和genetic screen来说zebrafish未必及的上medaka(是一种东亚
特有的鱼类),zebrafish的基因组测序的质量也一般吧。历史上主要由于其鱼卵子互
相不粘连比较适合观察不同发育时期而广泛使用。 |
|
b*********l 发帖数: 490 | 5 I am thinking another issue. During the process of zebrafish like fixation-
dehydration-rehydration, all of the MeOH+PBT solution should be with DEPC
treated water or what? Is it possible that the mRNAs in zebrafish have been
deteriated before the hybridizaion? I am not sure how bad the
invivo mRNA will be if I don't use RNase free reagents. The thing is I
couldn't see any difference between negative control and the real samples.
Thank you for any suggestions. |

M*****n 发帖数: 16729 | 13 not possible.
we have many fish facilities on campus and that department has at least
three faculty studying zebrafish, as I know.
i think only relatively smaller universities will have that kind of concern.
for bigger unversities, investing for a fish facility is not a big deal.
btw, for that mm, if she wants to kick off her proposed project, she does not need a big facility, besides, my feeling is she is going to migrate to mouse genetics. |

m****9 发帖数: 128 | 14 We submitted a paper to Cell and got response, the reviewer asked for in

We identified a tumor suppressor via activating TGF-b signaling, the

Can anyone give some information about this or recommend some nice guys that
we can cooperate with? It is better in Boston area.

w***y 发帖数: 493 | 15 我把3xHA的tag接到蛋白的N端, 然后做了in vitro transcription得到了mRNA. 接着把
mRNA注射到了鱼的卵里,另外准备了一些uninjected fish作为negative control, 一段
时间后做western观察蛋白表达情况. 我发现在那些negative control的样品里也有带,
而且量还不少, 大概在75KD 左右. 我试过两个不同的 anti-HA的抗体, 结果都一样.
请问有人在zebrafish里面表达过HA-tag的蛋白么, 有没有看到这种情况呢? |
|
s********8 发帖数: 619 | 16 你的意思是IRES更reliable吗? 刚才研究了下,好像说IRES的表达不能保证两个蛋白的
比例是1:1,而且zebrafish里面这个IRES的活性比较低,不知道是不是这样?
请大家多提意见吧,现在还没有决定到底用那个. |
