PDI2

(Synonyms: PSMA-DOTA-PEI2)

Avis client

Based on 1 Customer Validation

PDI2 (PSMA-DOTA-PEI2) is a prostate-specific membrane antigen (PSMA) ligand that acts as a tumor retention agent, renal uptake reducer, imaging agent and antitumor agent, applicable in SPECT diagnostic imaging and radiotheranostics. PDI2 specifically binds to PSMA on prostate cancer cells, enters cells via clathrin-dependent endocytosis, and exhibits higher tumor retention rate and lower renal uptake level. PDI2 is applicable in research related to prostate cancer and castration-resistant metastatic prostate cancer.

In Vitro

[¹¹¹In]In-PDI2 (0.195-50 nM; incubated on ice for 2 h) binds specifically to PSMA on LNCaP cells, with a K_d value of 22.8 nM^[1].
[¹¹¹In]In-PDI2 (37 kBq; incubated on ice for 2 h, incubated at 37°C for 0-4 h) shows an internalization rate of 38.9% in LNCaP cells^[1].

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

In Vivo

PDI2 (111 kBq; i.v.; single dose) exhibits high and persistent tumor uptake in the PSMA-positive LNCaP prostate cancer xenograft model, along with a favorable tumor-to-kidney radioactivity ratio^[1].
PDI2 (5-10 kBq; i.v.; single dose) effectively inhibits the growth of PSMA-positive LNCaP prostate cancer xenografts with no obvious toxicity^[1].

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

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.
