A lymphoid structure that arises within follicles after immunization with, or exposure to, a T cell-dependent antigen. It is specialized for facilitating the development of high-affinity, long-lived plasma cells and memory B cells. Aminophospholipid asymmetry of the plasma membrane The distribution ...
For RT-qPCR, it is ideal to choose a reverse transcriptase with high thermal stability, because this allows cDNA synthesis to be performed at higher temperatures, helping ensure successful transcription of RNA with high levels of secondary...

Protein structure蛋白质结构是指蛋白质分子在空间中的三维构象,包括其原子之间的相对位置和构象。蛋白质结构对蛋白质的功能和活性起着重要作用,因为蛋白质的结构决定其与其他分子的相互作用和信号转导的能力。蛋白质的结构可以分为四个层次:一级结构、二级结构、三级结构和四级结构。一级结构是指蛋白质分子中的氨基酸...
These nucleosomes form the building blocks of higher order chromatin structure. In its completely unfolded confirmation, the chromatin structures are visualised microscopically as 11-nm polymers with a “bead-on-string” appearance. According to the solenoid model of chromatin fiber, the nucleosomes ar...
106 Visualization of the microvascular structure of the tumors by magnifying NBI is therefore a useful tool for the differential diagnosis of T1a from T1b cancers. Esophagography is used for evaluating the shape, length, and location of tumor.107 EUS and CT are also used for evaluating the T...
