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. SIRT7, a mammalian homolog of Sir2, is localized primarily in the nucleolus and is most prominently expressed in hematopoietic cells, especially myeloid progenitor cells. SIRT7 is recruited to chromatin by sequence-specific DNA binding transcription factors such as Elk-4, where it functions to deacetylate Lys18 of histone H3 at gene promoters and facilitate transcriptional repression. Interestingly, overexpression of SIRT7 induces a global decrease in histone H3 Lys18 acetylation levels, a phenotype that has been associated with poor prognosis in prostate, lung, kidney, and pancreatic cancers in the research literature. Furthermore, studies have also shown that SIRT7 is required for the maintenance of several transformed phenotypes of cancer cells, including anchorage-independent cell growth, growth in low serum conditions, and tumor formation in xenograft assays. SIRT7 is also required for the E1A-induced decrease in histone H3 Lys18 acetylation, induction of cell-cycle entry, and escape from contact inhibition. Taken together, these findings strongly suggest that SIRT7 is an important regulator of cellular transformation. Research has shown that the SIRT7 gene is located on chromosome 17q25.3, a region that is frequently altered in acute leukemia and lymphoma, and SIRT7 overexpression and amplification have been detected in multiple types of cancer.

保存条件：
SIRT7 Rabbit Polyclonal Antibody -20ºC保存，Western一抗稀释液-20ºC或4ºC保存，一年有效。Western一抗稀释液优先推荐4ºC保存，长期不使用可以考虑-20ºC保存，但冻融可能会导致出现轻微的浑浊和少量不溶物。
注意事项：
如果本抗体用于Western blot (WB)、免疫荧光(IF)、免疫细胞化学(ICC)等实验，请注意回收使用过的稀释抗体。回收的抗体通常至少可以重复使用5-10次。稀释后的抗体，包括已经使用过的稀释抗体，请4℃保存。
回收后重复使用的抗体，使用方法同新鲜稀释的抗体。如果在重复使用过程中发现抗体出现轻微混浊现象，可以10,000g离心1-3分钟，取上清用于后续检测。如果回收的抗体出现明显的絮状物或长霉长菌等情况，则可以考虑废弃该抗体。
提供的Western一抗稀释液也可以用于免疫荧光(IF)、免疫组化(IHC)、免疫细胞化学(ICC)等适当用途。如果希望获得最佳的检测效果，请考虑使用上述检测专用的一抗稀释液。
