[BroadPharm] MagicLink™ HRP Antibody Conjugation Kit

 

MagicLink™ HRP Antibody Conjugation Kit

 

HRP can be conjugated to antibody/protein by thiol-maleimide and hydrazone coupling approaches. The

thiol-maleimide approach is commonly performed with a bi- functional linker (such as SMCC). However,

SMCC-modified protein is extremely unstable and often self-reactive since it often contains both amine and

thiol groups that cause significant amount of homo-crosslinking. The thiol-maleimide linkageis

exchangeable when other thiol groups are present. In the hydrazone coupling approach, 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.

   A typical flow chart of HRP -antibody conjugation by MagicLink technology

 

BroadPharm's MagicLink™ technology solves all the problems by combining PEG and proprietary

crosslinking chemistry. MagicLink™ chemistry and kit do not need TCEP, DTT, or catalysts at all!

First, antibody reacts with MAGIC NHS ester to yield the MAGIC activated antibody which instantly reacts

with LINK preactivated HRP to yield antibody-HRP conjugate with a stable ring linkage.

 

Features;

· Novelty: 3rd generation protein crosslink technology

· Yield: conjugation efficiency around 95-100%

· Rate: instant reaction; the whole process less than 1 hour
