——下面是ELN的二則po文—-搬來搬去, SF你真是有夠煩——–
2014/04/03 by mmiiee關於EBV infection的實驗, 以下是我的構想, 歡迎大家提供意見討論!
2014/04/02 sufang : 想不想把 TGF-b1 那一步拿掉? 我建議加一個6 h, 去掉72 h, 然後10天改為7天
2014/04/02/ mmiiee : from Dr. Chang 紀錄一下
- 重現之前high GFP(+) rate的實驗(穩定/確定條件)(30 % is good)
- 觀察GFP何時開始亮? GFP(+)細胞有無/何時分裂?
- control做好 (eg, UV-inactivated virus)
2014/04/03 mmiiee: 60~70% confluence細胞數 (in 6-well plate)
OKB2: 2×10^5/well
NP460hTert: 2.1~2.2 x10^5/well (ingrid noted)
- sufang: What about p21 and SFN、有p63也很不錯!, 另外、妳有LANA的PCR primer嗎? 有RCR, LCR那附近的gene primer嗎? thanks.
- mmiiee: 手上有的…p21, SFN, EBNA1(LCR), BKRF3, BKRF4(RCR), BHLF1, BHRF1(oriLyt)都有primer 剩下p63待設計!
- sufang: well, 那就不ㄧ定要p63
- natsumi : AC550 根據AC550 EBV infect into TW05,有加TGFb還是有差的,尤其是在濃縮病毒情況下。
- 1xSup -TGFb: 5.4% ==> +TGFb: 7.6%
- 10xSup -TGFb: 22% ==> +TGFb: 34%
- sufang : 可是、從來也沒有過只有1.1%這麼差呀! 難道culture medium也很有關係? drop 太多了,令人擔心…
- sufang: 加錯medium的問題 (1): 那Infection時,都還是在有10%FBS的情況下吧? (2): 可以請natsumi comment一下有沒有CO2真的會影響嗎? –> 在這講求省電環保的時代裡,為了一個可能不會影響太多的assay, 特別去開一個incubator實在很不環保啊. 知道為什麼要在沒有CO2的狀態下asasy嗎? thanks.
- ingrid : 那Infection時,還是在有10%FBS的情況下。(DF-K+ 10%FBS)
- natsumi: Sigma出的senescence kit上面有說明,如下 Note: The staining of senescent cells is pH dependent. Therefore, the cells cannot be incubated in a CO2 enriched atmosphere during the staining step. 其實之前在細胞培養箱染也沒有什麼問題,要解決的話,就放在細菌培養箱,周邊用Parafilm封好避免乾掉就好了。
- sufang: 周邊用Parafilm封好? 那放在原來有CO2的incubator不是也可以杜絕CO2進去? 就這樣子辦吧! 大家意下如何?
2014/04/11 ingrid: 部分結果出爐
2014/04/24 sufang: 來試寫一份我們家感染上皮細胞的Protocol怎麼樣? Ingrid: 是你將功贖罪的大好時機呦!! 你可以署名 「AMO」。
2014/04/28 ingrid: Rta蛋白質在EBV感染OKB2後有表現出來喔!!
- sufang: 讚! 濁水溪的Zta抗體好嗎? 我們沒有4F10了嗎? 同理,Argene的Rta比濁水溪的Rta好嗎? 張堯老師對我們的homemade Rta抗體真是讚不絕口。
- ingrid: 重新strip後,Zta抗體(4F10)及濁水溪的Rta皆沒有band。
- mmiiee : AC619_film 附上之前做HEK293 cells的結果與之比較(Akata EBV infected HEK293 cells for 48 hrs) Rta和Zta的size都比預期小(預期Rta約95 kDa, Zta約36 kDa), 這張blot出現的Rta約85 kDa, Zta約32 kDa和27 kDa
2014/05/15/2014 ingrid: Zta蛋白質在感染後的48h有偵測到,且size如預期大小一樣約為36kDa
- mmiiee : 抗體&時間點. NP460是不是沒希望啦, 50% positive還是測不到R/Z的話(還是來測測看EBNA1, 會不會全部都走latent去了?)
- 在OKB2這組實驗裡感覺Rta要用Argene比LTK更加sensitive, Zta用4F10比LTK好.
- Zta若一樣用75 ug/lane搞不好也可以在24h偵測到.
- 另外, 若用IF(免疫螢光染色)的話, 就可以區分GFP(+)到底走latent或lytic了!
- OKB2真是酷斃了! 可惜不是NP細胞 (嘆)
- sufang: LTK的抗體是兔子來的, 所以blocking時加入BSA是不是可以減少background? Cell Signaling或是Santa Cruz的兔子抗體,有沒有類似的建議 ?
2014/05/16 sufang 若能區分 latent vs lytic infection…
那就太好了, 我們現在有幾個點要釐清:
1. NP460hTert的50%感染率要能reproducible
2. hTert, the human terlomerase, 會不會幫助EBV走latency (if so, OKF4-hTert就會和NP460hTert一樣,只能感染卻測不到Z或R, 另外,maruko看到的那個primary NP cell就很值得購買)
3. NP cell vs oral keratinocyte是不是先天就有差。想像 DA Thowerly-Lawson大師提過EBV如何在口腔部細胞長成active lytic replication的plaque。相反的, NPC這邊多是latency狀態居多。
2014/04/23 ingrid: EBV Infection-II
2014/04/28 ingrid: 雖然細胞培養在不對的培養液中,但病毒綠光感染率仍有13% (w/TGF-b1)。
2014/04/29
- sufang: 恭喜, 但不懂.. 這次不是改正成養在正確的medium中了嗎? 妳是說infection前細胞都是養在DF-K的意思嗎? Infection 時細胞density仍然小於70%嗎?
- mmiiee: 幫忙回答: 完全正確的medium還沒有做喔, 這次實驗seeding下去仍發現很多漂的細胞, 加了TGF-b隔天選了一個接近70%的滿度做infection, 是做了infection之後才發現medium是錯的
- ingrid: 謝謝mmiiee的幫忙回答, 沒錯,是做了infection的當天下午,才想到medium是錯的……….
2014/05/05 ingrid: WB結果顯示測不到Rta及Zta蛋白質的表現
2014/05/05 ingrid : AE601
