- the disclosed technologies use a disuccinimidyl crosslinker, so the reactivity of the first carbonyl group and the second carbonyl group is equally high (see 2.2.). Accordingly, the reactivity of the first carbonyl group is high, and since there is no adjacency condition for the reaction, there is a high possibility that any lysine group is labeled.
- the antibody comprising the first functional group prepared according to the present invention has high uniformity and yield.
- the high uniformity of the conjugate product through antibody labeling means that (1) the function of the antibody conjugate conjugate is uniformly guaranteed, (2) the effect is predictable, so it is safe, and (3) There is an advantage in that it is possible to label by avoiding the functional site of the antibody, thereby avoiding the reduction of the function of the antibody.
- the first carbonyl group of the crosslinker according to the open technology has high reactivity, it does not have an adjacency condition for the reaction (see 5.5.). For this reason, there is a high possibility that the first carbonyl group will react with any lysine group. Therefore, there is a disadvantage that the uniformity and yield of the antibody-labeled product is lower than that of the present application.
- the antibody comprising the first functional group according to the present invention does not have its FcRn binding site shielded, by the antibody comprising the first chemical functional group according to the present application because the FcRn binding site is not blocked. which functions of the antibody are not decreased)

- the antibody is used in the body, that is, when used as a therapeutic agent, contrast agent, etc., if the interaction between the FcRn and the antibody does not occur smoothly, the half-life of the antibody is shortened and thus it may not function properly.
- Lysine 246 and Lysine 248 are separated from the FcRn binding site of the antibody (Lys246 and Lys248 are detached from the FcRn binding site of the antibody)
- the method for producing the antibody comprising the first functional group according to the present invention is characterized in that SSAI leaves during the method according to the present invention.
- the antibody comprising the first click-chemistry functional group according to the present application does not contain a highly bioreactive chemical functional group, so that side reactions other than the conjugate formation reaction do not occur (the antibody comprising first click-chemistry functional group according to the present invention does not comprise highly bioreactive functional group, by which no side reaction other than the conjugate forming reaction occurs)
- the antibodies produced by the production method of the R 1 '-Ab of the present application has the same structure as the general formula (7):
- R 1 ′ is delivered to lysine 246, or lysine 248, X 4 will be NH and D 1 will be any alkylene, alkenylene, or alkynylene.
- -NH-(CO)- linked to the antibody is an amide bond, which is generally a stable bond in the body, and D 1 is also a structure that is not highly bioreactive.
- R 1 is manufactured by the present application '-Ab is a labeled molecule (R 1' has to be expected High is not a highly reactive biological structure except part) safety (safety).
- R 1 ' if -Ab is a click chemistry moiety is a 1 H -Ab transfer, not have high bio-reactive structure part, a click on the secondary reaction other than a chemical reaction does not occur to improve the yield of a click chemistry reaction.
