oYo-Link® Tetrazine Antibody Labeling Kit - Labels 100ug

Research Use Only Applications: Click Chemistry with TCO (trans-cyclooctene)-bound molecules. oYo-Link® Tetrazine allows for the site-specific labeling of oYo-Link®-compatible antibodies with up to two tetrazine labels per antibody for subsequent copper-free click chemistry reactions with TCO (trans-cyclooctene)-bound molecules. oYo-Link® Tetrazine limits the attachment of the tetrazine labels to the heavy chains of the antibody and therefore ensures that the tetrazine label does not interfere with antibody binding. Furthermore, site-specific labeling limits 1-2 tetrazine labels to be attached per antibody, providing precise antibody-conjugate ratios. The antibody labeling procedure simply requires mixing oYo-Link® Tetrazine with the desired antibody followed by photocrosslinking with non-damaging black light (365 nm). Photocrosslinking can be carried out in most buffers, including those containing amine-containing molecules (e.g. TRIS, glycine) or storage proteins (see Buffer Compatibility Table) . Requirements: To label your compatible antibodies with oYo-Link®, you will need a Light Source emitting at 365nm (6-10W). Use your own Compatible Device from our list or purchase AlphaThera's LED Photo-Crosslinking Device.
