MLLT3 Knockout HEK293T Cells (MLLT3基因敲除HEK293T细胞)是通过同时表达Cas9、目的基因sgRNA和puromycin抗性基因,并实现了目的基因CRISPR敲除的HEK293T细胞。本细胞中目的基因的敲除已经通过T7EI法的验证。本细胞株是多克隆细胞,可用于该目的基因的生物学功能研究,也可以用于该基因相应抗体的验证。
本HEK293T Cells为可同时表达Cas9、puromycin抗性基因和目的基因sgRNA的慢病毒感染HEK293T细胞并经过puromycin筛选后获得的多克隆HEK293T细胞。制备本细胞的相应慢病毒的基因序列的关键图谱信息请参考图1。

本细胞中目的基因的敲除已经通过T7EI法的验证。
由于本细胞是通过CRISPR/Cas9技术获得的多克隆细胞,基于CRISPR/Cas9技术的特点,理论上平均有2/3的细胞发生移码突变而导致了目的基因的敲除,平均有1/3的细胞并未发生移码突变。很多情况下有约2/3的细胞发生目的基因的敲除,已经足以进行很多的目的基因的生物学功能的研究了。如果希望获得100%基因敲除的细胞,可以自行使用本产品筛选单克隆细胞,或者委托碧云天进行单克隆细胞株的筛选服务。
本细胞用于实验时,建议同时选购无任何靶向的对照细胞Control Knockout HEK293T Cells (L00020)或靶向GFP的对照细胞GFP Knockout HEK293T Cells (L00022)。
碧云天同时提供基于CRISPR/Cas9技术的MLLT3基因敲除的质粒(L28670 pLenti-MLLT3-sgRNA)、慢病毒(L28671 MLLT3 Knockout Lentivirus)、HEK293T细胞(L28672 MLLT3 Knockout HEK293T Cells)、HEK293T敲除细胞的RIPA裂解液(L28673 MLLT3 Knockout HEK293T RIPA Lysate)、HEK293T敲除细胞的Trizol裂解液(L28674 MLLT3 Knockout HEK293T Trizol Lysate)等产品等产品,具体请在碧云天网站查询或在本产品网页点击相应产品。

Gene Summary | Chromatin reader component of the super elongation complex (SEC), a complex required to increase the catalytic rate of RNA polymerase II transcription by suppressing transient pausing by the polymerase at multiple sites along the DNA (PubMed:20159561, PubMed:20471948, PubMed:25417107, PubMed:27105114, PubMed:27545619). Specifically recognizes and binds acylated histone H3, with a preference for histone H3 that is crotonylated (PubMed:25417107, PubMed:27105114, PubMed:27545619, PubMed:30374167, PubMed:30385749). Crotonylation marks active promoters and enhancers and confers resistance to transcriptional repressors (PubMed:25417107, PubMed:27105114, PubMed:27545619). Recognizes and binds histone H3 crotonylated at 'Lys-9' (H3K9cr), and with slightly lower affinity histone H3 crotonylated at 'Lys-18' (H3K18cr) (PubMed:27105114). Also recognizes and binds histone H3 acetylated and butyrylated at 'Lys-9' (H3K9ac and H3K9bu, respectively), but with lower affinity than crotonylated histone H3 (PubMed:25417107, PubMed:27105114, PubMed:30385749). In the SEC complex, MLLT3 is required to recruit the complex to crotonylated histones (PubMed:27105114, PubMed:27545619). Recruitment of the SEC complex to crotonylated histones promotes recruitment of DOT1L on active chromatin to deposit histone H3 'Lys-79' methylation (H3K79me) (PubMed:25417107). Plays a key role in hematopoietic stem cell (HSC) maintenance by preserving, rather than confering, HSC stemness (PubMed:31776511). Acts by binding to the transcription start site of active genes in HSCs and sustaining level of H3K79me2, probably by recruiting DOT1L (PubMed:31776511). AF9_HUMAN,P42568 |
