| 背景 | Suppressor of Ty-16 (SPT16) and structure-specific recognition protein-1 (SSRP1) are subunits of the facilitates chromatin transcription (FACT) complex that is essential for transcription elongation (1,2). FACT facilitates RNA polymerase-dependent transcription of chromatin templates by destabilizing the nucleosomes within the open reading frames of active genes (3-5). FACT destabilizes the nucleosomes, which would otherwise act as barriers to RNA polymerase transcription activity, by disrupting histone-histone and histone-DNA contacts that lead to the eviction of the histone H2A-H2B dimer (2,3,6). FACT may also function as a histone chaperone to reassemble nucleosomes after RNA polymerase passage (7). In addition to transcription, FACT activity has been shown to have a role in DNA replication in yeast and in DNA repair by contributing to the activation of p53 by CK2 and by facilitating histone H2AX-H2B exchange upon DNA damage (8-10). |

Western blot analysis of extracts from various cell lines using SSRP1 (E1Y8D) Rabbit mAb.Western blot方法检测不同细胞系的提取物，使用的抗体为SSRP1 (E1Y8D) Rabbit mAb。 | |
Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HCT 116 cells starved for 48 hr then serum stimulated with 20% FBS for 15 min and either 10 μl of SSRP1 (E1Y8D) Rabbit mAb or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human c-Fos Promoter Primers #4663, SimpleChIP® Human c-Fos Exon 3 Primers #12010, SimpleChIP® Human EGR1 Promoter Primers #5549, and SimpleChIP® Human EGR1 Intron 3 Primers #11953. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.使用SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003 对4 x 106 HCT 116细胞中交联过的染色质进行染色质免疫沉淀，细胞经过48小时饥饿培养并用20% FBS进行15min 血清刺激，所用抗体为10 µl SSRP1 (E1Y8D) Rabbit mAb或2 µl Normal Rabbit IgG #2729，富集到的DNA经过实时PCR定量，所使用产品为SimpleChIP® Human c-Fos Promoter Primers #4663, SimpleChIP® Human c-Fos Exon 3 Primers #12010, SimpleChIP®Human EGR1 Promoter Primers #5549,以及 SimpleChIP® Human EGR1 Intron 3 Primers #11953。每个样品中免疫沉淀得到的DNA量由与input chromatin( 相当于1)的相对信号值来表示。 |
