What is it?
BSA, Ovalbumin or Keyhole Limpet Hemocyanin (KLH) stimulate a large immune response and are typically used as carrier proteins to generate antibodies against small antigens (peptides or organic compounds). For success the antigen (normally referred to as a hapten) needs to be covalently linked to the carrier protein.

How it works
The imm-Link™ immunogen kits allow peptides and small molecules (Hapten) to be conjugated to a carrier protein (BSA, ovalbumin and KLH) simply by adding a solution of the hapten to a proprietary lyophilised mixture containing the carrier protein and all the required conjugation chemistry.

Hands-on time for the conjugation: Only 20-30 seconds!

Following successful conjugation the conjugate is dialysed in the supplied dialysis cartridge to remove unwanted by-products. The hapten conjugate can then be easily recovered and used.

Brilliant Flow Cytometry
Brilliant Violet™ antibody conjugates will change the future of flow cytometry, bringing new power, unparalleled sensitivity and resolution to the violet laser. Excitable at 405 nm wavelength, these fluorochromes bring dramatic improvements in brightness and signal-to-noise over the current choices for the violet laser.
Brilliant Microscopy
Where BD Horizon™ V450, Pacific Blue™ and eFluor® 405 are just too dim for fluorescence microscopy, Brilliant Violet 421™ now enables visualization of antigens with directly conjugated antibodies.
