蛋白交聯(lián)劑的分類應(yīng)用和反應(yīng)基團(tuán)介紹說(shuō)明-瑞禧生物

時(shí)間:2016-7-22閱讀:3132

蛋白交聯(lián)劑的分類】:

1:同源交聯(lián)劑:

具有兩個(gè)相同活化反應(yīng)基團(tuán)。應(yīng)用:一步反應(yīng),分子內(nèi)交聯(lián),多聚反應(yīng),穩(wěn)定四級(jí)結(jié)構(gòu)

 

 

2:異源交聯(lián)劑:

具有兩個(gè)不同活化反應(yīng)基團(tuán)。應(yīng)用:兩步反應(yīng)交聯(lián),可減少聚集和自身交聯(lián)。反應(yīng)原則:先反應(yīng)不穩(wěn)定活性基團(tuán)(與*種蛋白質(zhì)),然后去除掉未反應(yīng)的交聯(lián)劑,在加入種待交聯(lián)蛋白質(zhì),短臂用于分子間交聯(lián),長(zhǎng)臂用于分子內(nèi)交聯(lián)反應(yīng):SH……NH2, NH2…… COOH

 

3:光反應(yīng)交聯(lián)劑:

反應(yīng)原則:先交聯(lián)不穩(wěn)定的熱反應(yīng)活性基團(tuán)(與*種蛋白質(zhì)),然后UV交聯(lián),將*種蛋白質(zhì)交聯(lián)到種蛋白質(zhì)的N-HC-H上。特點(diǎn):交聯(lián)非特異性,產(chǎn)率低。

 

交聯(lián)劑的使用方法】:

圖示為同源交聯(lián)劑的使用方法:先將待交聯(lián)的蛋白質(zhì)A與交聯(lián)劑在一定條件下反應(yīng),得到的蛋白質(zhì)A-交聯(lián)劑中間體,然后移除多余的交聯(lián)劑,再加入欲交聯(lián)的蛋白質(zhì)B。產(chǎn)物中可能會(huì)形成多聚體,這一副產(chǎn)物通過(guò)調(diào)節(jié)反應(yīng)條件來(lái)控制。分成兩部反應(yīng)的目的在于減少分子內(nèi)交聯(lián)以及形成蛋白質(zhì)多聚物。另外,選擇異源交聯(lián)劑也可以減少多聚物的產(chǎn)生。

 

交聯(lián)劑的應(yīng)用】:

蛋白質(zhì)結(jié)構(gòu)研究

蛋白質(zhì)間相互作用研究

抗體的標(biāo)記、標(biāo)記轉(zhuǎn)移

蛋白質(zhì)與核酸的連接

蛋白質(zhì)修飾等 

 

選擇交聯(lián)劑應(yīng)考慮的因素】:

反應(yīng)特異性

反應(yīng)指向性

間臂長(zhǎng)度性

水溶性

透膜性

一種或兩種反應(yīng)基團(tuán)

熱反應(yīng)還是光電反應(yīng)

可否切斷

可否碘標(biāo)

 

可與交聯(lián)劑反應(yīng)的基團(tuán)】:

羧基(天冬氨酸,谷氨酸,末端羧基)

羥基(或蘇氨酸)

酮基,醛基,糖鏈

苯酚衍生物(苯丙氨酸,色氨酸,酪氨酸)

放射性基團(tuán): R-N3
