gold nanoparticles labeled dna - Because gold nanoparticles have the properties of surface plasmon resonance spectroscopy, in the construction of DNA analysis and detection, they have the advantage of being able to convert a biometric reaction into an amplified optical or electrical signal. Therefore, the combination of nano-gold and DNA is used to detect the bases, single strands and oligonucleotides of DNA. Using nanoparticles as tags to detect DNA is an interesting alternative to standard fluorescence techniques. This method has simple detection equipment, high stability and low cost.

dna crosslinking - Cross-linking agents are widely used to modify nucleic acids, drugs and polymers. The same principle applies to protein modification and labeling. Based on factors such as reactivity and spacer length, the reagents used for cross-linking are divided into different types, each with its own specific functions and applications. Chemical crosslinking is mainly formed by covalent bonds. The cross linker may be hydrophobic to allow access to the hydrophobic protein domain, either through the cell membrane, or hydrophilic, to limit cross-linking to the water chamber. CXMS, a chemical cross-linked peptide identification technique based on biological mass spectrometry, can provide rich experimental information for the study of protein folding and protein-protein interaction.

fluorescein labeled dna - Oligonucleotides are polymer sequences of nucleotides (RNA, DNA and their analogues). Health diagnosis and drug gene research were carried out by using primers and siRNA, oligonucleotides for basic molecular research, as well as microarray and fluorophore probes. Fluorophore is a very useful biomolecule sensitive marker, and fluorescent labeling is the most commonly used synthetic oligonucleotide marker so far. Many different fluorescent groups can be easily connected to oligonucleotides, which form the basis of the detection systems used in DNA sequencing, forensic medicine, and genetic analysis.
