Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 NCCIT cells and either 10 μl of Oct-4A (C52G3) 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 Oct-4 Promoter Primers #4641, SimpleChIP® Human Sox2 Promoter Primers #4649, and SimpleChIP® Human α Satellite Repeat Primers #4486. 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将4 x 106 NCCIT细胞与10μl Oct-4A (C52G3)Rabbit mAb兔单抗或2μl Normal Rabbit IgG#2729进行染色质免疫共沉淀。富集到的DNA使用SimpleChIP® 人Oct-4启动子引物#4641,SimpleChIP® 人Sox2启动子引物#4649和SimpleChIP® 人α卫星重复序列引物#4486进行荧光实时PCR定量。各样品沉淀得到的DNA量显示为与input染色质总量相对定量,Input中染色质量设定值为1。


Oct-4 (POU5F1) is a transcription factor highly expressed in undifferentiated embryonic stem cells and embryonic germ cells (1). A network of key factors that includes Oct-4, Nanog, and Sox2 is necessary for the maintenance of pluripotent potential, and downregulation of Oct-4 has been shown to trigger cell differentiation (2,3). Oct-4 is a useful germ cell tumor marker (4). Oct-4 exists as two splice variants, Oct-4A and Oct-4B (5). Recent studies have suggested that it is the Oct-4A isoform that has the ability to confer and sustain pluripotency and that Oct-4B may exist in some somatic, non-pluripotent cells (6,7).

Oct-4 (POU5F1)是一类高表达于未分化胚胎干细胞和原始胚胎生殖细胞中的转录因子(1),一系列关键因子包括Oct-4, Nanog和 Sox2对保持多潜能性是必需的,Oct-4的下调显示能起始细胞分化(2,3)。Oct-4是一种非常有用的生殖细胞肿瘤标志物[4]。Oct-4存在两种剪接异构体Oct-4A and Oct-4B(5)。近来研究暗示Oct-4A异构体能给予并保持干细胞多潜能,而Oct-4B可能存在于某些体细胞和非多潜能性细胞中(6,7)。
