Our focus: antibodies targeting small molecules

ImmuSmol stands for “immunoglobulins [antibodies] against small molecules”. While traditional antibodies only recognize large molecules such as proteins, ImmuSmol designs and develops antibodies capable of targeting low molecular weight entities (<900 Da).

Amino acids, lipids, saccharids, toxins, drugs, … virtually any small molecule can thus be addressed with high affinity and specificity. Fully compatible with existing antibody-based technologies, small molecule antibodies are opening a whole new set of possibilities in research, diagnostics and therapy.

Three core applications

  • Research antibodies - ImmuSmol sells validated primary antibodies, for small molecule detection and visualization in cells and tissues.


Target class:


Kynurenine pathway metabolites

Serotonin pathway metabolites


Catecholamine metabolism


Food safety

Neuroendocrine tumor markers

Arginine metabolism

Amino acids
