Application Notes
This antibody binds to The original version of this antibody (mouse Fab) was shown to bind testosterone with a Kd of 0.3 nM and an ED50 of 4.8 nM (Valjakka et al., 2002; PMID: 12196551). The binding mechanism of this antibody was explored via crystallography (Niemi et al., 2011; 21360611).
Antibody First Published
Valjakka et al. Crystal structure of an in vitro-affinity- and specificity- matured anti-testosterone Fab in complex with testosterone. Improved affinity results from small structural changes within the variable domains. Journal of Biological Chemistry 2002; 277(46):44021-44027 PMID:12196551
Note on publication
The original publication describes the generation and structural analysis of a highly selective, high-affinity anti-testosterone Fab fragment, highlighting small structural changes within the variable domains that result in improved affinity and specificity through comprehensive packing of testosterone with the protein.
