實驗注意事項:
1、 把聚丙烯酰胺凝膠中的蛋白質(zhì)電泳轉(zhuǎn)移到硝酸纖維膜上;
a. 轉(zhuǎn)移緩沖液洗滌凝膠和硝酸纖維素膜,將硝酸纖維素膜鋪在凝膠上,用5ml移液管在凝膠上來回滾動去除所有的氣泡
b. 在凝膠/濾膜外再包一張3mm濾紙(預(yù)先用轉(zhuǎn)移緩沖液浸濕),將凝膠夾在中間,保持濕潤和沒有氣泡
c. 將此濾紙/凝膠/薄膜濾紙按照廠家建議方法放入電泳裝置中,凝膠面向陰極
d. 將上述裝置放入緩沖液槽中,并灌滿轉(zhuǎn)移緩沖液以淹沒凝膠
e. 按照廠家所示接通電源開始電泳轉(zhuǎn)移
f. 轉(zhuǎn)移結(jié)束后,取出薄膜和凝膠,棄去凝膠
2、 將薄膜漂在氨基黑中快速染色,直至分子量標(biāo)準(zhǔn)顯現(xiàn)時取出,記錄下標(biāo)準(zhǔn)位置;
3、 用100ml水洗滌纖維素膜,必要時可用脫色緩沖液;
4、 膜置印跡緩沖液中于37℃保溫1小時;
5、 室溫下,用PBS-Tween緩沖液洗滌薄膜
6、 用封口機將薄膜封入塑料袋中,盡可能不留空氣;
7、 袋的一角剪一緩沖液的小口,用透析袋夾緊;
8、 混合:NGS(100微升),印跡緩沖液中的抗體(2.5-5毫升),加在裝薄膜的袋中,于室溫下?lián)u動2小時(或4℃過ye);
9、 用總體積300ml PBS-Tween緩沖液,分4次在一淺盤中洗滌薄膜,每次75ml;
10、將連接*的羊抗兔IgG(40微升溶于10毫升印跡緩沖液/100微升 NGS)加在袋內(nèi),于室溫下?lián)u動1小時;
11、按步驟9洗滌;
12、加入抗生素蛋白-HRP(40微升溶于10毫升印跡緩沖液/100微升 NGS),于室溫下?lián)u動;
13、Western Blot中轉(zhuǎn)移在膜上的蛋白處于變性狀態(tài),空間結(jié)構(gòu)改變,因此那些識別空間表位的抗體不能用于Western Blot檢測。這種情況可以將表達目的蛋白的細胞或細胞裂解液中的所有蛋白物素化,再用酶標(biāo)記親和素進行Western Blot。實驗中取膠和膜需帶手套。

背景介紹:The widely studied P53 tumor suppressor gene has been found to contain mutations in over 50% of human cancers. The level of P53 protein is low in normal cells, but is increased in response to DNA damage or various other cellular distress signals. Overexpression of the P53 transcription factor can induce ether cell cycle arrest or apoptosis through transcriptional regulation of several genes including the cell cycle ingibitor P21, DNA repair gene GADD45, and the apoptotic inducer Bax. P53 has also been shown to induce apoptosis by meas of s direct signaling pathway. P53 directly binds to and acts on several cellular protein involved in various pathway, including c-Abl, basal transcription factor TFIIH and WT1. P53 can be functionally inactivated by mutation, binding to DNA tumor virus encoded proteins, such as SV40 large T antigen, Adenovirus E1B and papilloma virus E6 proteins or as a consequence of its interaction with the oncogene-encoded protein MDM2. This antibody is recognize the Human P53 Core Domain Mutant N235KN239Y.
