Absolute Mag™ SARS-CoV-2 Spike S1 protein Conjugated Magnetic Particles(WHM-AB04)


Absolute Mag™ SARS-CoV-2 Spike S1 protein Conjugated Magnetic Particles (# WHM-AB04 #) are obtained by coupling the biotinylated SARS-CoV-2 Spike S1 protein to streptavidin conjugated magnetic particles, which can capture the Anti- SARS-CoV-2 antibody or ACE2 protein from cell or serum sample and easily to follow up with other tests, such as immunocapture, biopanning and flow cytometry. These magnetic particles will be supplied as lyophilized powder (from 0.22 μm filtered PBS pH7.4 including 0.05% Tween-20 and 10% trehalose).
