C19orf48 Knockout HEK293T Trizol Lysate (C19orf48基因敲除HEK293T细胞Trizol裂解液)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敲除的多克隆HEK293T细胞的Trizol裂解液。该细胞中目的基因的敲除已经通过T7EI法的验证。本产品可用于该目的基因敲除后其信号通路相关RNA表达的研究。
本Trizol裂解液源于可同时表达Cas9、目的基因sgRNA和puromycin抗性基因的慢病毒感染HEK293T细胞并经过puromycin筛选后获得的多克隆HEK293T细胞。制备该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。

该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Trizol裂解液用于实验时，建议同时选购无任何靶向的对照细胞Trizol裂解液Control Knockout HEK293T Trizol Lysate (L00031)或靶向GFP的对照Trizol裂解液GFP Knockout HEK293T Trizol Lysate (L00033)。

| Gene Summary | C19orf48 as the gene encoding a novel minor H antigen presented by HLA-A*0201 and recognized by CTL clones isolated from two patients with metastatic RCC who were treated with nonmyeloablative HLA-identical allogeneic HCT. The C19orf48 gene, first identified by the Mammalian Gene Collection Program, was subsequently cloned from a cisplatin-resistant human lung adenocarcinoma cell line. Sequence analysis of C19orf48 transcripts predicted a 117-residue translation product encoded by the largest ORF that is located in both the NM_199250 and NM_199249 transcripts. The studies of T cell recognition of C19orf48 provide direct evidence for a translation product derived from a novel ORF in the +2 frame of NM_199250 that encodes a predicted polypeptide of only 48 residues. Although differential splicing of 5 exons result in the alternative C19orf48-derived transcripts NM_199249 or NM_199250 that are discordant for the ORF encoding the antigenic 48-residue protein, our analyses of transcript expression by both northern blot and Q-PCR demonstrate that the NM_199250 transcript encoding the antigenic 48 residue polypeptide is the dominant transcript, with expression levels that are 100- to 600-fold greater than the expression levels of NM_199249. Discovery of the C19orf48-encoded minor H antigen within an unrecognized ORF adds to a growing body of data demonstrating that minor H peptides can be derived from surprisingly short protein species encoded by unconventional or occult ORFs. The C19orf48 genomic locus lies between the androgen-regulated testicular acid phosphatase (ACPT) gene and the androgen-regulated kallikrein gene cluster on chromosome 19q. |
