Site-specific Labeling of B Cell Receptor and Soluble Immunoglobulin B细胞受体和可溶性免疫球蛋白的定位标记 作者:Yu Wang, Zhixun Shen, Zhengpeng Wan and Wanli Liu日期:09/20/2020,浏览量:469,Q&A: 0
B lymphocyte activation is regulated by its membrane-bound B cell receptors (BCRs) upon recognizing diverse antigens. It is hypothesized that antigen binding would trigger conformational changes within BCRs, followed by a series of downstream signaling activation. To measure the BCR conformational changes in live cells, a fluorescent site-specific ...

Whole-genome Identification of Transcriptional Start Sites by Differential RNA-seq in Bacteria 细菌转录起始位点的差异RNA序列全基因组鉴定 作者:Ramón Cervantes-Rivera and Andrea Puhar日期:09/20/2020,浏览量:410,Q&A: 0
Gene transcription in bacteria often starts some nucleotides upstream of the start codon. Identifying the specific Transcriptional Start Site (TSS) is essential for genetic manipulation, as in many cases upstream of the start codon there are sequence elements that are involved in gene expression regulation. Taken into account the classical gene ...
