NOTA-SP2A-PSMAL

NOTA-SP₂A-PSMAL is a ligand targeting prostate-specific membrane antigen (PSMA), which competitively binds to PSMA with high binding affinity and an IC₅₀ value of 0.26 nM. ¹⁸F-labeled NOTA-SP₂A-PSMAL can be used as a PET tracer for positron emission tomography imaging of prostate cancer. NOTA-SP₂A-PSMAL can be used for the synthesis and research of radionuclide conjugates (RDCs).

In Vitro

NOTA-SP₂A-PSMAL exhibits a binding energy of -10.2 K_cal/mol and forms equivalent hydrogen bonds with human PSMA protein compared to NOTA-PSMA-BCH, indicating comparable binding stability^[1].
NOTA-SP₂A-PSMAL (10^-12 to 10^-5 M; 60 min) competitively binds to PSMA in 22Rv1 cells with high binding affinity (IC₅₀ = 0.26 nM)^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
