Background
The Silent Information Regulator (SIR2) family of genes is a highly conserved group of genes that encode nicotinamide adenine dinucleotide (NAD)-dependent protein deacetylases, also known as Class III histone deacetylases. The first discovered and best characterized of these genes is Saccharomyces cerevisiae Sir2, which is involved in silencing of mating type loci, telomere maintenance, DNA damage response and cell aging. SIRT3, a mammalian homolog of Sir2, exists in human cells in two forms. The full-length 44 kDa protein localizes to the nucleus, while a processed 28 kDa protein lacking 142 amino terminal residues localizes exclusively to the mitochondria. The single murine form of SIRT3 is equivalent to the processed human SIRT3 protein. Full-length SIRT3 protein is processed in the mitochondrial matrix by the mitochondrial matrix processing peptidase (MMP). Both full-length and processed forms of SIRT3 are enzymatically active and de-acetylate histone H3 at Lys9 and histone H4 at Lys16 in vitro . SIRT3 also de-acetylates Lys642 of acetyl-CoA synthetase 2 (AceCS2) and activates AceCS2 activity in the mitochondria. Restricted caloric intake, which is linked to increased lifespan in multiple organisms, increases SIRT3 expression in white and brown adipocytes of obese mice, suggesting a role for SIRT3 in aging. Two observations implicate SIRT3 in the regulation of mitochondrial thermogenesis. First, exposure to cold temperatures increases SIRT3 expression in brown adipocytes, while elevated temperatures reduce SIRT3 expression. Second, over-expression of SIRT3 results in increased levels of the mitochondrial uncoupling protein 1 (UCP1). SIRT3 protein levels are also elevated in certain breast cancers.

保存條件：
SIRT3 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?；厥盏目贵w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。
