PBS Only antibodies refer to antibody preparations formulated solely in PBS as the storage buffer, typically without the addition of stabilizers or preservatives such as BSA, gelatin, glycerol, or sodium azide. Compared with conventional antibody preparations containing protein stabilizers or ...

Once a cell sample enters a preservation system, the analytical result is no longer determined solely by its original biological state, but is instead jointly influenced by the anticoagulation mode, osmotic environment, buffering conditions, degree of metabolic suppression, and processing ...

Fluorophores are light-emitting molecules or materials that absorb energy upon excitation at specific wavelengths and emit photons at longer wavelengths. They are widely used in cell imaging, flow cytometry, immunoassays, nucleic-acid quantification, protein–protein interaction analysis, and ...

Experimental Steps for Methanol Permeabilization & Triton X-100 Permeabilization

The detection of cell surface proteins mainly targets antigens on the cell membrane. Antibodies can directly bind to antigens on the cell surface, so fixation and permeabilization treatment are usually not required. The experimental operation is relatively simple, and the main focus is on the ...

Flow cytometry is a powerful technique that is often used to analyze surface and internal antigens of cells. When detecting intracellular antigens, cells usually need to be fixed and permeabilized.

An isotype control antibody appears like a typical antibody but it does not attach itself to a specific target protein like the primary antibody used in the experiment.

Flow cytometry (FCM) is a single-cell quantitative analysis and sorting technique using flow cytometry. Flow cytometry is a product of highly developed and comprehensive use of monoclonal antibodies and immunocytochemistry, lasers and computer science, etc. It can effectively differentiate ...
