Specificity / Sensitivity

Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb (Biotinylated) detects endogenous levels of histone H3 only when phosphorylated at Ser10.

Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb兔单抗(Biotinylated)能够检测仅在Ser10位点磷酸化的内源性histone H3的蛋白水平。

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser10 of human histone H3.

通过合成的与人源histone H3蛋白Ser10位点周围相应的磷酸化片段去免疫动物从而制备出此单克隆抗体。


This Cell Signaling Technology antibody is conjugated to biotin under optimal conditions. The unconjugated Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb #3377 reacts with phospho-histone H3 (Ser10) from human, mouse, rat, and monkey. CST expects that Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb (Biotinylated) will also recognize phospho-histone H3 (Ser10) in these species.

Cell Signaling Technology antibody以最佳条件偶联了biotin。非偶联的Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb #3377可与人源、小鼠、大鼠和猴的phospho-histone H3 (Ser10)发生反应。CST公司的Phospho-Histone H3 (Ser10) (D2C8) XP® Rabbit mAb (Biotinylated)也可能识别这些物种的phospho-histone H3 (Ser10)蛋白。

Modulation of chromatin structure plays an important role in the regulation of transcription in eukaryotes. The nucleosome, made up of DNA wound around eight core histone proteins (two each of H2A, H2B, H3, and H4), is the primary building block of chromatin (1). The amino-terminal tails of core histones undergo various post-translational modifications, including acetylation, phosphorylation, methylation, and ubiquitination (2-5). These modifications occur in response to various stimuli and have a direct effect on the accessibility of chromatin to transcription factors and, therefore, gene expression (6). In most species, histone H2B is primarily acetylated at Lys5, 12, 15, and 20 (4,7). Histone H3 is primarily acetylated at Lys9, 14, 18, 23, 27, and 56. Acetylation of H3 at Lys9 appears to have a dominant role in histone deposition and chromatin assembly in some organisms (2,3). Phosphorylation at Ser10, Ser28, and Thr11 of histone H3 is tightly correlated with chromosome condensation during both mitosis and meiosis (8-10). Phosphorylation at Thr3 of histone H3 is highly conserved among many species and is catalyzed by the kinase haspin. Immunostaining with phospho-specific antibodies in mammalian cells reveals mitotic phosphorylation at Thr3 of H3 in prophase and its dephosphorylation during anaphase (11).

染色质结构的修饰在调节真核细胞的转录中扮演着重要的角色。由DNA围绕和八聚体组蛋白(H2A,H2B,H3和H4各两个)共同组成的核小体是染色质的主要组成(1)。核小体的组蛋白氨基酸尾端进行不同的转录后修饰,包括乙酰化,磷酸化,甲基化和泛素化(2-5)。这些修饰通过不同的刺激产生并且对转录因子能否接近染色质有着直接的影响,所以也影响着基因的表达(6)。在大多数的物种中组蛋白H2B主要在Lys5,,12,,15和20位点上发生乙酰化(4,7)。组蛋白H3主要是在Lys9,14,18,23,27和56位点上发生乙酰化。在某些物种里H3上的Lys9位点发生乙酰化并应该在组蛋白沉积和染色质组装中扮演着重要的角色(2,3)。组蛋白H3上Ser10,Ser28和Thr11位点的磷酸化在有丝分裂和无丝分裂中都与染色质的缩合紧密相连(8-10)。H3的Thr3位点的磷酸化在许多物种中都是高度保守的,是由kinase haspin所催化的。在哺乳动物中用磷酸化特异性的抗体做免疫组化显示H3的Thr3位点在有丝分裂的前期发生磷酸化,后期发生去磷酸化(11)。
