一般描述
双硫腙（Diphenylthiocarbazone）可用作锌的螯合剂。 由于它可与金属形成稳定的络合物，因而广泛用于各种金属的液-液和固相萃取中。
应用
双硫腙（Diphenylthiocarbazone）可用于体外分化胚胎干细胞培养中分化胰岛簇的表征，因为它与胰岛中大量存在的锌形成螯合物，从而选择性染色。在用火焰原子吸收法对银进行痕量级别定量之前，可在浊点预浓缩步骤中与银离子形成络合物。

Embryonic stem (ES) cells have a pluripotent ability to differentiate into a variety of cell lineages in vitro. We have recently identified the emergence of cellular clusters within differentiated ES cell cultures by staining with dithizone (DTZ). DTZ is a

In this work, a new coupling of spectrophotometric determination with preconcentration method named as ultrasound-assisted emulsification dispersive liquid-liquid microextraction (UAE-DLLME) for trace silver was firstly established. Disperser solvent in traditional DLLME was substituted by ultrasound-assisted emulsification, which could afford more

Despite improvements in outcomes for human islet transplantation, characterization of islet preparations remains poorly defined. This study used both light microscopy (LM) and electron microscopy (EM) to characterize 33 islet preparations used for clinical transplants. EM allowed an accurate identification
