Flow characterisitcs in a peristaltic bioreactor.
KAGAKU KOGAKU RONBUNSHU, 1989 蠕動型バイオリアクターの流動特性を流れの可視化実験により検討した.染料注入法による実験から, 蠕動壁面近傍の流体は前進, 後退を繰り返しながら次第に前進し, 容器中央部の流体は同様に前進, 後退を繰り返しながら次第に後退することが観察された.また, 容器内の流体は仮想壁面で区切られた領域内でのみ運動することがわかった.トレーサー追跡法によって求めた水平方向速度分布から, 仮想壁面の存在が実際に示された.さらに, 水平方向速度分布の相似性が認められた.断面流量について解析的に考察を加え, 仮想壁面が波長の整数倍ごとに存在することを示した.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Three-Dimensional Flow Analysis of Peristaltic Flow.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1998 A peristaltic flow is solved by finite difference method. The flow in peristaltic pump is three-dimensionally by the effect of the side walls. Since the actual peristaltic flow has a secondary flow in its cross section against the streamwise direction, so the three-dimensional flow analysis should be employed.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments
FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

FEBS Open Bio, EarlyView.We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...
