  • Hygromycin B(潮霉素B)應(yīng)儲(chǔ)存在干燥、陰涼的地方

    2025-8-11
    HygromycinB(潮霉素B)主要通過(guò)抑制細(xì)胞內(nèi)的蛋白質(zhì)合成來(lái)發(fā)揮其作用。它能夠特異性地結(jié)合到真核生物細(xì)胞的80S核糖體上,干擾核糖體的功能,阻礙氨基酸在核糖體上的裝配以及肽鏈的延伸過(guò)程。具體而言,可與核糖體28SRNA的某些特定區(qū)域相結(jié)合,改變核糖體的構(gòu)象,使得tRNA無(wú)法準(zhǔn)確地將氨基酸轉(zhuǎn)運(yùn)至核糖體上進(jìn)行肽鍵的形成,從而導(dǎo)致蛋白質(zhì)合成的終止。這種對(duì)蛋白質(zhì)合成的抑制作用是劑量依賴(lài)性的,在一定濃度范圍內(nèi),隨著潮霉素B濃度的增加,對(duì)蛋白質(zhì)合成的抑制效果更為顯著。Hygromy...
  • Hygromycin B(潮霉素B)的三大優(yōu)點(diǎn)

    2025-8-5
    在基因工程領(lǐng)域,HygromycinB(潮霉素B)常被用作篩選標(biāo)記。當(dāng)將含有潮霉素B抗性基因(如hyg)的外源基因?qū)肽繕?biāo)細(xì)胞后,只有成功整合并表達(dá)該抗性基因的細(xì)胞才能在含有潮霉素B的培養(yǎng)環(huán)境中存活下來(lái)。這是因?yàn)榭剐曰蚰軌蚓幋a一種特殊的酶,這種酶可以對(duì)潮霉素B進(jìn)行修飾或降解,使其失去對(duì)細(xì)胞的毒性作用。例如,在某些植物轉(zhuǎn)基因操作中,將攜帶潮霉素B抗性基因的質(zhì)粒導(dǎo)入植物細(xì)胞,經(jīng)過(guò)一段時(shí)間的培養(yǎng),未成功轉(zhuǎn)化的細(xì)胞由于缺乏抗性基因,其蛋白質(zhì)合成被潮霉素B嚴(yán)重抑制,然后死亡;而成功轉(zhuǎn)...
  • RPMI-1640培養(yǎng)基可避免血清中復(fù)雜成分對(duì)細(xì)胞生長(zhǎng)的潛在干擾

    2025-5-14
    RPMI-1640培養(yǎng)基之所以能夠在眾多培養(yǎng)基中脫穎而出,其關(guān)鍵在于其精心調(diào)配的成分和設(shè)計(jì)理念。作為一種無(wú)血清培養(yǎng)基,它避免了血清中復(fù)雜成分對(duì)細(xì)胞生長(zhǎng)的潛在干擾,使得細(xì)胞培養(yǎng)更加穩(wěn)定、可控。同時(shí),培養(yǎng)基中豐富的營(yíng)養(yǎng)物質(zhì)、氨基酸、維生素和礦物質(zhì)等成分,為細(xì)胞提供了生長(zhǎng)支持,確保了細(xì)胞在體外環(huán)境中的健康生長(zhǎng)和增殖。此外,RPMI-1640培養(yǎng)基還采用了碳酸氫鹽緩沖系統(tǒng),這一系統(tǒng)能夠有效地維持培養(yǎng)基的pH值穩(wěn)定,為細(xì)胞提供一個(gè)恒定的酸堿環(huán)境。這對(duì)于細(xì)胞的正常代謝和生理功能至關(guān)重要,...
