A simple and accurate high-performance liquid chromatography (HPLC) coupled with diode array detector (DAD) and evaporative light scattering detector (ELSD) was established for the determination of six bioactive compounds in Zhenqi Fuzheng preparation (ZFP). The monitoring wavelengths were 254, 275 and 328 nm. Under the optimum conditions, good separation was achieved, and the assay was fully v...
Zinc Finger Targeter (ZiFiT) is a simple and intuitive web-based tool that facilitates the design of zinc finger proteins (ZFPs) that can bind to specific DNA sequences. The current version of ZiFiT is based on a widely employed method of ZFP design, the 'modular assembly' approach, in which pre-existing individual zinc fingers are linked together to recognize desired target DNA sequences. Seve...
The vertebrate genome contains a large number of Krüppel-associated box-zinc finger genes that encode 10 or more C(2)-H(2) zinc finger motifs. Members of this gene family have been proposed to function as transcription factors by binding DNA through their zinc finger region and repressing gene expression via the KRAB domain. To date, however, no Krüppel-associated box-zinc finger protein (KRAB-...
ZFN technology is a powerful research tool and has been used for genome editing in cells lines, animals and plants. The generation of functional ZFNs for particular targets in mammalian genome is still challenging for an average research group. The modular-assembly method is relatively fast, easy-to-practice but has a high failure rate. Some recent studies suggested that a ZFP with low binding ...

For the first time, artificial cellulosome structures were created on DNA scaffolds based on zinc finger protein (ZFP)-guided assembly. These resulting two-component cellulosome structures exhibited enhancement in cellulose hydrolysis compared to the non-complexed mixture depending on the number of CBMs and cellulases assembled.
Zinc finger transcription factors (TFs(ZF)) were designed and applied to transgene and endogenous gene regulation in stably transformed plants. The target of the TFs(ZF) is the Arabidopsis gene APETALA3 (AP3), which encodes a transcription factor that determines floral organ identity. A zinc finger protein (ZFP) was designed to specifically bind to a region upstream of AP3. AP3 transcription wa...
BACKGROUND It has been hypothesized that the critical closing pressure of cerebral circulation, or zero-flow pressure (ZFP), can estimate intracranial pressure (ICP). One ZFP estimation method used extrapolation of arterial blood pressure as against blood-flow velocity. The aim of this study was to improve ICP predictions. METHODS Two revisions have been considered: (1) the linear model used ...
