Magnetic immunostaining is a technique used to accelerate the antigen-antibody immunoreaction by increasing the local density of antibody on the surface of a tissue specimen using a magnetic field. The high density of antibody is achieved by applying a magnetic force to antibody-labeled ferrite beads toward the specimen. A technical challenge of using conventional magnets for this tec... https://www.alarecre.com/Wizarding-World-Harry-Potter-Scar-and-Glasses-iPhone-13-Pro-MagSafe-Case-p90262/
