用于检测、定量和定位抗原与抗体的技术——ELISA、免疫印迹、免疫组化与流式细胞术。以下是我们知识库中标注该主题的实验方案、常见问题与技术文章。
Nucleases are enzymes that catalyze the hydrolysis of phosphodiester bonds in DNA or RNA. They play fundamental roles in nucleic acid extraction, sample purification, contamination control, and molecular experiment quality control.
核酸酶是一类能够催化DNA或RNA磷酸二酯键水解的酶，在核酸提取、样本纯化、污染控制和分子实验质控中具有基础性作用。
RNA提取是转录组学研究与分子检测流程的基础环节。其关键在于：在最短时间内失活RNase并完成充分裂解，使RNA以尽可能完整的形态释放。
RNA extraction is a foundational step in transcriptomics research and molecular diagnostic workflows. The key requirements are to inactivate RNases and achieve thorough lysis as rapidly as possible, thereby releasing RNA in a form that is as intact as feasible.
In molecular biology workflows, RNA exhibits relatively low chemical stability because its single-stranded conformations often expose bases and the phosphate backbone, and because the 2′-hydroxyl group enables base-catalyzed transesterification. Under these conditions, even trace RNase ...
The DNA of apoptotic cells is cut into fragments of about 200 base pairs under the action of caspase-activated nuclease (CAD), forming DNA ladders. By detecting DNA fragmentation during apoptosis, the degree of apoptosis can be evaluated.
凋亡细胞的DNA会在caspase激活的核酸酶（CAD）作用下被切割成约200个碱基对的片段，形成DNA梯状结构（DNA ladders）。通过检测细胞凋亡过程中DNA片段化现象，可以评估细胞凋亡的程度。
RNA extraction and reverse transcription experiments are key technologies used in molecular biology to study gene expression and function. RNA extraction is the separation of complete, impurity-free RNA from cells or tissues, while reverse transcription is the conversion of RNA into cDNA for ...
RNA提取和反转录实验是分子生物学中用于研究基因表达和功能的关键技术。RNA提取是从细胞或组织中分离出完整、无杂质的RNA，而逆转录则是将RNA转化为cDNA，以便用于后续的PCR扩增或测序分析。
