CCR5 Knockout HEK293T Cells (CCR5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)。

Gene Summary | This gene encodes a member of the beta chemokine receptor family, which is predicted to be a seven transmembrane protein similar to G protein-coupled receptors. This protein is expressed by T cells and macrophages, and is known to be an important co-receptor for macrophage-tropic virus, including HIV, to enter host cells. Defective alleles of this gene have been associated with the HIV infection resistance. The ligands of this receptor include monocyte chemoattractant protein 2 (MCP-2), macrophage inflammatory protein 1 alpha (MIP-1 alpha), macrophage inflammatory protein 1 beta (MIP-1 beta) and regulated on activation normal T expressed and secreted protein (RANTES). Expression of this gene was also detected in a promyeloblastic cell line, suggesting that this protein may play a role in granulocyte lineage proliferation and differentiation. This gene is located at the chemokine receptor gene cluster region. An allelic polymorphism in this gene results in both functional and non-functional alleles; the reference genome represents the functional allele. Two transcript variants encoding the same protein have been found for this gene. |
