Background
DNA topoisomerases play essential roles in many DNA metabolic processes including DNA repair. Topoisomerases can introduce DNA damage upon exposure to drugs that stabilize the covalent protein-DNA intermediate of the topoisomerase reaction. Lesions in DNA are also able to trap topoisomerase-DNA intermediates. DNA topoisomerase I (Top1) catalyzes the relaxation of supercoiled DNA by a mechanism of transient DNA strand cleavage characterized by the formation of a phosphotyrosyl bond between the DNA end and active site tyrosine. The antitumor agent camptothecin (CPT) reversibly stabilizes the covalent enzyme-DNA intermediate by inhibiting DNA religation. When a replication fork collides with a DNA Top1 cleavage complex, the covalently bound enzyme must be removed from the DNA 3' end before recombination-dependent replication restart. The tyrosyl-DNA phosphodiesterase Tdp1 and the structure-specific endonuclease Rad1-Rad10 function as primary alternative pathways of Top1 repair in Saccharomyces cerevisiae. In the budding yeast S. cerevisiae, DNA topoisomerases I and II can functionally substitute for each other in removing positive and negative DNA supercoils.

保存條件:
???????Topoisomerase I Rabbit Monoclonal Antibody -20℃保存，Western一抗稀釋液-20℃或4℃保存，一年有效。Western一抗稀釋液優(yōu)先推薦4℃保存，長(zhǎng)期不使用可以考慮-20℃保存，但凍融可能會(huì)導(dǎo)致出現(xiàn)輕微的渾濁和少量不溶物。
注意事項(xiàng):
???????如果本抗體用于Western blot (WB)、免疫熒光(IF)、免疫細(xì)胞化學(xué)(ICC)等實(shí)驗(yàn)，請(qǐng)注意回收使用過(guò)的稀釋抗體?；厥盏目贵w通常至少可以重復(fù)使用5-10次。稀釋后的抗體，包括已經(jīng)使用過(guò)的稀釋抗體，請(qǐng)4℃保存。
???????回收后重復(fù)使用的抗體，使用方法同新鮮稀釋的抗體。如果在重復(fù)使用過(guò)程中發(fā)現(xiàn)抗體出現(xiàn)輕微混濁現(xiàn)象，可以10,000g離心1-3分鐘，取上清用于后續(xù)檢測(cè)。如果回收的抗體出現(xiàn)明顯的絮狀物或長(zhǎng)霉長(zhǎng)菌等情況，則可以考慮廢棄該抗體。
???????提供的Western一抗稀釋液也可以用于免疫熒光(IF)、免疫組化(IHC)、免疫細(xì)胞化學(xué)(ICC)等適當(dāng)用途。如果希望獲得的檢測(cè)效果，請(qǐng)考慮使用上述檢測(cè)專用的一抗稀釋液。
???????本產(chǎn)品僅限于專業(yè)人員的科學(xué)研究用，不得用于臨床診斷或治療，不得用于食品或藥品，不得存放于普通住宅內(nèi)。
???????為了您的安全和健康，請(qǐng)穿實(shí)驗(yàn)服并戴一次性手套操作。
