RNA fluorescence in situ hybridization
A nucleic acid probe is a tool for detecting a specific nucleic acid molecule at the molecular level. For better qualitative, semi-quantitative or relative positioning analysis, specific nucleotides can be labeled with a reporter group (such as biotin or fluorescein). Such labeling can be visualized by immunochemical reaction or directly by fluorescence detection, so that the nucleic acid to be detected (such as mRNA, lncRNA, circRNA, miRNA) can be analyzed under the mirror. This method is relatively simple and has a wide range of applicability, so it is widely used in the field of biology.
Technical principle
RNA-FISH is an experimental method for analyzing a target nucleic acid in a cell or tissue section to be detected. This method uses homologous complementary nucleic acid probes to form hybrids with the target nucleic acid through a process of denaturation-annealing-renaturation. One of the nucleotides in the nucleic acid probe is labeled with a specific reporter molecule, such as biotin or fluorescein. Through immunochemical reaction or fluorescence detection system, using the role of reporter molecules and fluorescein labeled avidin, can be detected nucleic acids (mRNA, lncRNA, circRNA, miRNA) qualitative, semi-quantitative or relative positioning analysis. The principle of this method is clear, easy to operate, and can provide accurate and attractive experimental results.

Plasma experiment service
Cold atmospheric plasma (CAP) is an emerging tumor treatment method that has been shown to be selective for many types of cancer cells, providing new opportunities for effective treatment of various cancers. CAP is a plasma generated at room temperature and atmospheric pressure, and has shown great potential for biomedical applications due to a favorable combination of reactive physical and chemical species, such as UV radiation, electrons, free radicals, ions, and excited molecules. Recently, it has been found that plasma activated medium (PAM) produced by exposure of aqueous media to CAP is as effective as direct CAP in inhibiting cancer cells, thereby increasing the range and flexibility of plasma-based therapy.

Electrophysiological Experiment Service
Electrophysiological platform: The brain slice patch clamp system consists of amplifier, digital-to-analog converter, micro-operation, electrode drawing instrument, microscope and perfusion system. With a special glass micropipette adsorbed on the cell surface membrane, and then the implementation of the membrane voltage clamp, can measure the current of the magnitude of pA generated by the opening of a single ion channel. It can also be used to detect the cell excitability (action potential and model index), ion channel (potassium sodium calcium ion) and synaptic transmission (excitatory synaptic transmission and inhibitory synaptic transmission) in the brain slice of the desired site of drug/experimental treatment.
