Nucleosomes are barriers to RNA Polymerase II (Pol II) transcribing along gene bodies in eukaryotes. We found that a fragile “tailless nucleosome” could be generated to resolve the Pol II pausing ...

Multichannel pipettes are invaluable when working with multiwell plates. However, prolonged and repetitive pipetting sessions bear the risk of strain and fatigue, often resulting in repetitive strain ...

Reliable tip sealing and firm tip attachment are of key importance for efficient pipetting. With this in mind, we have re-engineered the connection between pipette and tip. By designing the GripTips ...

Here we studied three well-characterized human medulloblastoma (Med) cells lines: Daoy, D341 Med and D283 Med. Extensive histochemical and xenograft studies have shown that these cells are arrested ...

Whenever your skin is injured—whether by accident or from surgery — your body works to repair the wound. As your skin heals, a scar may form, as this is a natural part of the healing process. The ...

Micropipettes are common laboratory devices used to accurately dispense small volumes of liquid samples. This course will focus on the principles of micropipetting used in biotechnology and other ...

Abstract: This paper presents a system integration approach for a 6-DoF (Degree of Freedom) collaborative robot to operate a pipette for liquid dispensing. Its technical development is three-fold.
