Background | Nucleotide excision repair (NER) is a process by which cells identify and repair DNA lesions that result from chemical and radiation exposure. The DNA binding protein XPA is an essential part of a pre-incision complex that forms at sites of damage, and is necessary for the initiation of nucleotide excision repair. XPA is one of eight NER proteins (XPA-G, XPV) encoded by genes that are defective in cases of xeroderma pigmentosum, a disorder characterized by sensitivity to sunlight, predisposition to exposed tissue cancers, and neurological defects in some patients. Activation of XPA follows phosphorylation at Ser196 and results in increased NER activity. Phosphorylation of XPA at Ser196 is induced by UV exposure in an ATR-dependant fashion and promotes nuclear accumulation of XPA. Research studies suggest that XPA may be a direct substrate of the serine/threonine kinase ATR and that NER activity may be negatively regulated through dephosphorylation of Ser196 by the phosphatase WIP1. |

保存條件:
XPA Rabbit Polyclonal Antibody (KO Validated) -20ºC保存,Western一抗稀釋液-20ºC或4ºC保存,一年有效。Western一抗稀釋液優先推薦4ºC保存,長期不使用可以考慮-20ºC保存,但凍融可能會導致出現輕微的渾濁和少量不溶物。
注意事項:
如果本抗體用于Western blot (WB)、免疫熒光(IF)、免疫細胞化學(ICC)等實驗,請注意回收使用過的稀釋抗體。回收的抗體通常至少可以重復使用5-10次。稀釋后的抗體,包括已經使用過的稀釋抗體,請4℃保存。
回收后重復使用的抗體,使用方法同新鮮稀釋的抗體。如果在重復使用過程中發現抗體出現輕微混濁現象,可以10,000g離心1-3分鐘,取上清用于后續檢測。如果回收的抗體出現明顯的絮狀物或長霉長菌等情況,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)、免疫細胞化學(ICC)等適當用途。如果希望獲得最佳的檢測效果,請考慮使用上述檢測專用的一抗稀釋液。
本產品僅限于專業人員的科學研究用,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。
