Homotrimer. Interacts with p300/EP300; the interaction occurs on chromatin in UV-irradiated damaged cells. Interacts with CREBBP (via transactivation domain and C-terminus); the interaction occurs on chromatin in UV-irradiated damaged cells. Directly interacts with POLD1, POLD3 and POLD4 subunits of the DNA polymerase delta complex, POLD3 being the major interacting partner; the interaction with POLD3 is inhibited by CDKN1A/p21(CIP1). Forms a complex with activator 1 heteropentamer in the presence of ATP. Interacts with EXO1, POLH, POLK, DNMT1, ERCC5, FEN1, CDC6 and POLDIP2. Interacts with APEX2; this interaction is triggered by reactive oxygen species and increased by misincorporation of uracil in nuclear DNA. Forms a ternary complex with DNTTIP2 and core histone (By similarity). Interacts with KCTD10 (PubMed:15982757). Interacts with PPP1R15A (By similarity). Directly interacts with BAZ1B. Interacts with HLTF and SHPRH. Interacts with NUDT15. Interaction is disrupted in response to UV irradiation and acetylation. Interacts with CDKN1A/p21(CIP1) and CDT1; interacts via their PIP-box which also recruits the DCX(DTL) complex. The interaction with CDKN1A inhibits POLD3 binding. Interacts with DDX11. Interacts with EGFR; positively regulates PCNA. Interacts with PARPBP. Interacts (when ubiquitinated) with SPRTN; leading to enhance RAD18-mediated PCNA ubiquitination. Interacts (when polyubiquitinated) with ZRANB3. Interacts with SMARCAD1. Interacts with CDKN1C. Interacts with PCLAF (via PIP-box). Interacts with RTEL1 (via PIP-box); the interaction is direct and essential for the suppression of telomere fragility. Interacts with FAM111A (via PIP-box); the interaction is direct and required for PCNA loading on chromatin binding. Interacts with LIG1. Interacts with SETMAR. Interacts with ANKRD17. Interacts with FBXO18/FBH1 (via PIP-box); the interaction recruits the DCX(DTL) complex and promotes ubiquitination and degradation of FBXO18/FBH1. Interacts with POLN.
功能:
Auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase's processibility during elongation of the leading strand. Induces a robust stimulatory effect on the 3'-5' exonuclease and 3'-phosphodiesterase, but not apurinic-apyrimidinic (AP) endonuclease, APEX2 activities. Has to be loaded onto DNA in order to be able to stimulate APEX2. Plays a key role in DNA damage response (DDR) by being conveniently positioned at the replication fork to coordinate DNA replication with DNA repair and DNA damage tolerance pathways. Acts as a loading platform to recruit DDR proteins that allow completion of DNA replication after DNA damage and promote postreplication repair: Monoubiquitinated PCNA leads to recruitment of translesion (TLS) polymerases, while 'Lys-63'-linked polyubiquitination of PCNA is involved in error-free pathway and employs recombination mechanisms to synthesize across the lesion.
亚细胞位置:
Nucleus
Forms nuclear foci representing sites of ongoing DNA replication and vary in morphology and number during S phase. Together with APEX2, is redistributed in discrete nuclear foci in presence of oxidative DNA damaging agents. Colocalizes with CREBBP, EP300 and POLD1 to sites of DNA damage (By similarity).

大鼠增殖细胞核抗原(Pcna)ELISA试剂盒原理?
双抗体夹心法:用纯化的抗体包被微孔板,制成固相抗体,往包被有固相抗体的微孔中依次加入标准品或受检样本、生物素化抗体、HRP标记的亲和素,经过彻底洗涤后用底物TMB显色。用酶标仪在450nm波长下测定吸光度(OD值),计算样本浓度。
竞争法:用纯化的抗体包被微孔板,制成固相抗体,往包被有固相抗体的微孔中依次加入标准品或受检样本和生物素标记的目标分析物,受检标本中抗原与生物素标记抗原竞争结合有限的抗体。再加入HRP标记的亲和素,经过彻底洗涤后用底物TMB显色。用酶标仪在450nm波长下测定吸光度(OD值),计算样本浓度。

大鼠增殖细胞核抗原(Pcna)ELISA试剂盒中需要使用的样品量是多少?
夹心法100μL/孔,竞争法50μL/孔。如样本浓度过高时,应对样本进行稀释,以使稀释后的样本符合试剂盒的检测范围,计算时再乘以相应的稀释倍数。
[6].
如何分析大鼠增殖细胞核抗原(Pcna)ELISA试剂盒数据?
建议标准曲线,并计算样本浓度。对于elisa的曲线拟合,一般建议采用4参数曲线拟合,4参数曲线拟合通常更适合免疫分析。推荐使用专业软件进行曲线拟合,例如curve expert 1.3。根据样本的OD值由标曲查出相应的浓度,再乘以稀释倍数;或用标准物的浓度与OD值计算出标曲的回归方程式,将样本的OD值代入方程式,计算出样本浓度,再乘以稀释倍数,即为样本的实际浓度。以下链接是curve expert 1.3软件拟合曲线的方法。

收集大鼠增殖细胞核抗原(Pcna)ELISA试剂盒血浆样本,用什么作为抗凝剂?
一般建议用EDTA和肝素作为抗凝剂。
