應用

在琼脂糖凝胶中染色DNA,DAPI比溴化乙锭敏感几倍。它可用于DNA的光足迹图谱,通过对双链复合体的特殊可视化检测印迹应用中的退火探针,并使用流式细胞分析术研究DNA中的变化并分析凋亡过程中的DNA含量。DAPI染色也是一种敏感和特异的支原体检测方法。

生化/生理作用

DNA的细胞渗透性荧光小沟结合探针。与双链DNA的小沟(富含AT的DNA优先)结合,形成稳定的复合物,其发出的荧光比单独的DAPI高约20倍。

Polycomb repressive complexes are evolutionarily conserved complexes that maintain transcriptional repression during development and differentiation to establish and preserve cell identity. We recently described the fundamental role of PRC1 in preserving intestinal stem cell identity through the inhibition of non-lineage-specific

Infection induces the expression of inflammatory chemokines that recruit immune cells to the site of inflammation. Whereas tissues such as the intestine and skin express unique chemokines during homeostasis, whether different tissues express distinct chemokine profiles during inflammation remains unclear.

Autographa californica multiple nucleopolyhedrovirus (AcMNPV) ac96 is a core gene, but its role in virus replication is still unknown. To determine its role in the baculovirus life cycle, we used the AcMNPV bacmid system to generate an ac96-null virus (vAc(96)(null)).

Rearrangement hotspot (Rhs) and related YD-peptide repeat proteins are widely distributed in bacteria and eukaryotes, but their functions are poorly understood. Here, we show that Gram-negative Rhs proteins and the distantly related wall-associated protein A (WapA) from Gram-positive bacteria mediate

In stroke and proliferative retinopathy, despite hypoxia driven angiogenesis, delayed revascularization of ischemic tissue aggravates the loss of neuronal function. What hinders vascular regrowth in the ischemic central nervous system remains largely unknown. Using the ischemic retina as a model
