DOTA-SMIC-1014

DOTA-SMIC-1014 is a DOTA chelator-conjugated precursor of the c-Met-targeting peptide SMIC-1014 (HY-P11863). DOTA-SMIC-1014 binds to the extracellular domain of c-Met (K_d = 42.83 nM). After radiolabeling to [⁶⁸Ga]Ga-SMIC-1014, DOTA-SMIC-1014 acts as a positron emission tomography (PET) probe that achieves specific tumor uptake in xenografts and functions as a diagnostic probe targeting c-Met. SMIC-1014 can be used in research related to colon cancer, hepatocellular carcinoma, and prostate cancer.

For research use only. We do not sell to patients.

In Vitro

[⁶⁸Ga]Ga-SMIC-1014 binds to c-Met on HCT-116 human colon cancer cells, with a K_d value of 42.83 nM and a B_maxvalue of 188291 CPM, indicating high binding affinity^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

DOTA-SMIC-1014 (800-fold molar excess; i.v.; single coinjection with [⁶⁸Ga]Ga-SMIC-1014) significantly blocks specific c-Met-targeted tumor uptake of [⁶⁸Ga]Ga-SMIC-1014 in HCT-116 xenografts mice, reducing uptake by ~66% at 30 minutes post-injection^[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.
