Description

This recombinant monoclonal antibody is a research-grade biosimilar of empasiprubart (ARGX-117), targeting complement component C2, a soluble complement protein that is essential to the classical and lectin pathways. Upon pathway activation, C2 associates with C4b to form the C4bC2 (C3 proconvertase) complex, which is then processed to generate the C3 convertase (C4b2a)—a central enzymatic step that amplifies complement activation and drives downstream effector processes such as opsonization, inflammatory mediator release, and terminal pathway activation.

Empasiprubart is described as a humanized “sweeping” anti-C2 monoclonal antibody with pH- and Ca²⁺-dependent binding, designed to inhibit C2 function and thereby block classical/lectin pathway activation upstream of C3 by preventing formation of the C4bC2 complex. This biosimilar enables researchers to investigate C2-driven complement biology, including pathway initiation/amplification mechanisms and complement-dependent injury models, and to develop/benchmark assays that quantify classical/lectin pathway inhibition (e.g., C3 deposition readouts) in controlled experimental systems.

Usage
It is a non-therapeutic biosimilar antibody, owning the same variable region from the corresponding approved therapeutic antibody. In conclusion, it is a research-grade biosimilar antibody and expressed in mammalian cell, which can be directly used as positive controls in drug discovery or used for rapid verification of the biological functions of target protein.

Target Background

Function
Component C2 which is part of the classical pathway of the complement system is cleaved by activated factor C1 into two fragments: C2b and C2a. C2a, a serine protease, then combines with complement factor C4b to generate the C3 or C5 convertase.

  1. Vag8 binding to human C1-inhibitor (C1-inh) interferes with the binding of C1-inh to C1s, C1r and MASP-2, resulting in the release of active proteases that subsequently cleave C2 and C4 away from the bacterial surface. PMID: 28742139

  16. Upon cleavage by C1s, C2a domains undergo conformational rotation while bound to C4b and the released C2b domains may remain folded together as seen in the intact protein. PMID: 19237749
