Gold nanorods are rod-shaped nanoparticles made of gold, with dimensions ranging from a few nanometers to hundreds of nanometers. These nanoparticles have unique and rich physical and chemical properties, such as high surface electric field intensity enhancement and tunable photothermal conversion efficiency. These properties make gold nanorods ideal for applications...

Studying the spatial distribution of proteomes in cells is crucial for understanding various molecular mechanisms in cell biology. In recent years, proximity chemical labeling technology, especially APEX (Engineered Ascorbate Peroxidase), has rapidly advanced. This method enables proximity labeling of proteins and RNA in specific spatial regions within living cells, avoiding...

FM series fluorescent dyes include FM 1-43, FM 2-10, FM 5-95, and FM 4-64. They are a type of lipophilic styrene fluorescent dyes that are non-toxic to cells and are mainly used for living cell membranes, especially plant samples. Specific labeling of cell membranes, tracer imaging of neuronal cells, and...

Conventional methods for attaching single-stranded DNA (ssDNA) to IgG antibodies often face several challenges. These include high costs associated with ssDNA modification, low coupling efficiency, complex reaction and purification processes, and difficulties in controlling the stoichiometry between ssDNA and IgG.  Professor Hang Xing from Hunan University developed the "AND Linker”,...

The difference between spotting capillary and sealed melting point capillary1. Production methodThe production of spotting capillaries is generally made by tangentially connecting glass capillaries and pipettes. The production process mainly includes three steps: tip treatment, tube wall protection and filling. Among them, the treatment of the tube tip is the...

Syringe filters are essential consumables in laboratories and industrial applications, such as biology, chemistry, environmental science, medicine, and pharmaceuticals, designed for the filtration and clarification of liquids before analysis, chromatography, or storage. Selecting the right syringe filter ensures sample integrity, reproducibility, and protection of instruments such as High-performance liquid chromatography...
