Description

Fluorogenic Zn(II) sensor for isolation of stem cell derived β cells

DA ZP1 (diacetylated Zinpyr1) is a fluorogenic Zn(II) sensor (Kd Zn2+ = 0.6 nM). It can be used to image and isolate pancreatic β-cells and β-like cells in vitro. Used to purify live stem cell-derived β-like cells. It can image transplanted islet grafts and endogenous mouse islets in vivo. DA ZP1 is non-fluorescent in the absence of Zn(II) ions but its binding with Zn(II) promotes hydrolytic cleavage of the acetyl groups, generating a strong fluorescent signal. Excitation and emission maxima (λ) are 490 nm and 522 nm, respectively.
