Techniques for detecting, quantifying and localizing antigens and antibodies — ELISA, Western blotting, immunohistochemistry and flow cytometry. Below are the protocols, FAQs and technical articles in our knowledge base tagged with this topic.
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.
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.
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 ...
