MagicLink™ Protein Protein Crosslinking Kit

Overview     
Protein-protein crosslinking can be achieved by the hydrazone method and thiol-maleimide method.
Thiol-maleimide method is commonly performed with a bifunctional linker, such as the commonly used SMCC. However, SMCC-modified protein is extremely unstable and often self-reactive since proteins often contain both amine and thiol groups that cause significant amount of homo-crosslinking. The maleimide conjugates can re-arrange, hydrolyze, or exchange in the presence of thiols/cysteine.

In the hydrazone coupling method, the conjugation reaction is based on a reaction between hydrazine and aldehyde. This method is low yielding although a catalyst is used. The size of the molecule and inaccessibility of the functional group contribute to low yield. In addition, linkage stability is an issue.

The novel technology of BroadPharm's MagicLink™ has been engineered to solves all the problems above and allow rapid and quantifiable conjugation of all classes of biomolecules. MagicLink™chemistry and kit and do not need TCEP, DTT, or catalysts at all!
First, two proteins are activated by MAGIC NHS ester and LINK NHS ester separately, and then the MAGIC activated proteins reacts instantly with the LINK preactivated protein to yield protein- protein conjugates with a stable ring linkage.
  • Novelty: 3rd generation protein crosslink technology
  • Yield: conjugation efficiency around 95-100%
  • Rate: instant reaction; the whole process less than 1 hour
  • Linkage stability: most stable covalent bonded conjugates on the market
  • Consistence: good reproducibility from batch to batch
  • Flexible: use your own protein-protein ratio
  • Shelf life: long, stable freeze dried ship at ambient temperature
  • Antibody selection: any proteins/antibody, antibody fragment
  • Post-conjugation clean-up step not necessary
  • Protein selection: any proteins/antibody, antibody fragment, fluorescent polymer such as BV 421, BV510, BV570, BV605, BV 650, BV 711, BV 785, PE, APC, or amine modified oligo, oligo- BV tandem dye, oligo-PE, oligo-APC conjugates, enzyme, oligo, etc.
