The oYo-Link® Technology
Simple, fast, site-Specific antibody labeling
How it works
oYo-Link® reagents consist of low molecular weight (~8 kDa), high-affinity antibody-binding domains that possess a photo-crosslinker within their Fc-binding site. Upon illumination with non-damaging Black-light, oYo-Link forms a covalent bond with the antibody.
Site Specific Antibody Labeling
Uniform labeling of up to 2 labels per Antibody on the heavy chain resulting in improved antibody performance, highly uniform product, and consistent, predictable results.
