FOLD4 Antibody

Potential Explanations for the Absence of "FOLD4 Antibody"

The lack of references to "FOLD4 Antibody" could stem from:

1. Nomenclature Error: The term may be a misnomer or a proprietary name not widely recognized in academic literature.

2. Emerging Research: The antibody may be in preclinical development, with no published data yet available.

3. Structural Prediction Tools: "FOLD" appears in methodological contexts (e.g., HelixFold-Multimer and IgFold in ), but these refer to antibody structure prediction algorithms, not therapeutic antibodies.
