| Background | Protein kinase R (PKR) is transcriptionally induced by interferon and activated by double-stranded RNA (dsRNA). PKR inhibits translation initiation through phosphorylation of the α subunit of the initiation factor eIF2 (eIF2α) and also controls the activation of several transcription factors, such as NF-κB, p53, and the Stats. In addition, PKR mediates apoptosis induced by many different stimuli, such as LPS, TNF-α, viral infection, and serum starvation. Activation of PKR by dsRNA results in PKR dimerization and autophosphorylation of Thr446 and Thr451 in the activation loop. Substitution of threonine for alanine at position 451 completely inactivated PKR, while a mutant with a threonine to alanine substitution at position 446 was partially active. Research studies have implicated PKR activation in the pathologies of neurodegenerative diseases, including Alzheimer's disease. |

| AZ050 | Western一抗稀釋液 | 50ml |
| — | 說明書 | 1份 |
保存條件：
PKR/Eif2ak2 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(yōu)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(dǎo)致出現(xiàn)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(xué)(ICC)等實驗，請注意回收使用過的稀釋抗體�；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)使用過的稀釋抗體，請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。如果回收的抗體出現(xiàn)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(xué)(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(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，請穿實驗服并戴一次性手套操作。
