RIPA裂解液?(RIPA?Lysis Buffer) ????C1053

?

描述:?RIPA裂解液(RIPA Lysis Buffer)對(duì)動(dòng)物細(xì)胞胞膜、胞漿、胞核成分均有較強(qiáng)裂解作用,是經(jīng)典最常用的細(xì)胞組織快速裂解液。使用RIPA?裂解緩沖液制備用于Western特別是用于免疫共沉淀的裂解產(chǎn)物已經(jīng)是一種首選的標(biāo)準(zhǔn)操作,適用于大部分抗原表位檢測(cè),特別免疫共沉淀等實(shí)驗(yàn)

?

組成:?100 ml??RIPA裂解緩沖液。

成分:50 mM Tris-HCl (pH 7.4), 150 mM NaCl, 1% NP-40, 0.1% SDS.

?

儲(chǔ)存:4?℃保存 ?12個(gè)月有效

?

制備細(xì)胞裂解產(chǎn)物

1.?800g ?4℃離心5分鐘收集培養(yǎng)細(xì)胞,估計(jì)細(xì)胞離心后的體積(PCV,?106?cells=~20?ml, 107?cells =~100?ml?PCV);

2.?50100?ml PCV加入5倍體積RIPA裂解緩沖液(250~500?ml,冰浴放置10分鐘,并每隔5分鐘在漩渦混合儀上振蕩30秒;

3.?12000g ?4℃離心10分鐘,將上清轉(zhuǎn)移到新的離心管中,即得細(xì)胞總蛋白產(chǎn)物。

注意:如所得蛋白產(chǎn)物較為粘稠,可先95℃加熱5分鐘,迅速冰浴5分鐘,再進(jìn)行步驟3

?

制備組織裂解產(chǎn)物

1.?50-100?mg組織在冰上剪成碎片,用預(yù)冷的PBS洗滌2次離心棄去PBS

2.?加入?0.5-1 ml?預(yù)冷?RIPA?裂解緩沖液;

3.?4℃用玻璃勻漿器勻漿20-40次,直到95%的細(xì)胞被破碎,然后在冰浴中放置10分鐘,并每隔5分鐘在漩渦混合儀上振蕩30秒;

4.?12000g ?4℃離心10分鐘,將上清轉(zhuǎn)移到新的離心管中,即得組織總蛋白產(chǎn)物。

注意:如所得蛋白產(chǎn)物較為粘稠,可先95℃加熱5分鐘,迅速冰浴5分鐘,再進(jìn)行步驟4

?

說明:?

1.?轉(zhuǎn)移上清液時(shí)不要吸入底部的沉淀物;

2.?在做免疫沉淀或免疫共沉淀時(shí)最好在實(shí)驗(yàn)前進(jìn)行蛋白提取,避免某些不穩(wěn)定蛋白的降解;

3.?RIPA裂解緩沖液中未加入蛋白酶抑制劑,用戶可自行選擇添加。
