ZD2 peptide

ZD2 peptide is an EDB-FN-binding peptide with a K_d value of 11 μM. ZD2 peptide binds specifically to the EDB protein fragment of extradomain B fibronectin, a tumor microenvironment biomarker. ZD2 peptide can be conjugated to imaging agents. ZD2 peptide can be used for the research of cancer.

Description

In Vitro

Cyclic ZD2 peptide exhibits moderate binding affinity to the EDB-FN protein fragment with a K_d of 11 μM as measured by surface plasmon resonance^[1].
Linear ZD2 peptide conjugated to Gd(HP-DO3A) exhibits higher binding affinity to the EDB-FN protein fragment with a K_d of 1.7 μM as measured by surface plasmon resonance^[1].
Linear ZD2 peptide conjugated to Gd(HP-DO3A) as ZD2-N3-Gd(HP-DO3A) (MT218) exhibits moderate binding affinity to the EDB-FN protein fragment with a K_d of 3.45 μM as measured by surface plasmon resonance^[1].
Cyclic ZD2 peptide specifically binds to EDB-FN in aggressive human prostate cancer sections, as confirmed by competitive blocking with an anti-EDB-FN monoclonal antibody^[1].

In Vivo

ZD2−N3-Gd(HP-DO3A) (0.02-0.04 mmol/kg; i.v.; single dose) produces dose-dependent MRI signal enhancement in PC3 prostate cancer xenografts in rats, with a 3-fold CNR at 0.02 mmol/kg and a 6-fold CNR at 0.04 mmol/kg, while showing no significant enhancement in EDB-FN_low tumors^[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.
