Description

ATAC21, a linker-immune-stimulatory compound that can be formed by conjugating a noncleavable maleimide-PEG4 linker containing a succinimide group with an immune- stimulatory compound. ATAC21 can be combined with SBT-040 (anti-CD40 antibody) to form a conjugate[1].

In Vitro

A recombinant bispecific antibody, comprises: a) a target antigen binding domain, wherein the target antigen binding domain specifically binds to a tumor associated antigen; b) an effector antigen binding domain, wherein the effector antigen binding domain specifically binds to an antigen on an antigen presenting cell and wherein the antigen is a molecule on the antigen presenting cell; c) an Fc comprising domain; and d) an immune- stimulatory compound attached to the recombinant bispecific antibody by a linker; wherein the recombinant bispecific antibody induces greater immune cell activation when the recombinant bispecific antibody is bound to the tumor associated antigen and to the antigen on the antigen presenting cell as compared to when the recombinant bispecific antibody is bound to the antigen on the antigen presenting cell but not to the tumor associated antigen[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
