连续120h的细胞杀伤分析助力TP53新型抗体发现

；（B）绿色荧光蛋白（GFP）标记的TYK-nu与T细胞共培养，E:T比为5:1，有或没有H2-scDb在Incucyte®系统中连续监测，显示24小时和96小时拍摄的相位和绿色荧光图像。 研究人员基于 CRISPR 的技术对携带内源性 HLA-A*02:01 和 p53R175H 的 KMS26、KLE 和 TYK-nu 癌细胞系中的 TP53 进行了基因破坏。H2-scDb 介导的细胞毒性通过破坏这些细胞中的 TP53 类似地减轻，通过Incucyte® 连续检测超过120h，呈现动态的定量

Virion Attachment and Entry: HIV gp120 Env Biotinylation, gp120 Env, or Integrin Ligand-Binding Assay

The HIV-1 entry receptors are CD4 and a chemokine receptor (CCR5 or CXCR4). In addition it has recently been demonstrated that HIV-1 gp120 binds to and signals through integrin α4 β7 , the gut-homing receptor (Arthos et al., Nat Immunol

Inhibition of HIV Infection by Lectin Binding to gp120

Human immunodeficiency virus (HIV) is the causative agent of AIDS (acquired immunodeficiency syndrome). The polypeptide precursor gp160 of HIV-1 forms the external glycoprotein, gp120 and the transmembrane glycoprotein, gp41 (1 ). Sequence
