alkaline phosphatase staining to track cell reprogramming
28 Jun 2021
A new non-invasive technique scans “chemical fingerprints” to see if ordinary cells’ reprogramming into stem cells is on track and verify transformation success by matching “print” patterns.

We developed a multidimensional vibrational circular dichroism system with position and time coordinates using a quantum cascade laser (QCL) as a light source to achieve high intensity and narrow focusing. The QCL emitted light in the wavenumber range of 1500–1740 cm-1, which encompassed absorption bands assigned to the stretching vibrations of amides I and II. A scanning device was installed to move an attached motorized stage in two dimensions.

Researchers at Kanazawa University report in Analytical Chemistry an efficient method for filling a batch of nanopipettes with a pore opening below 10 nanometer. The method is based on the application of a temperature gradient to the nanopipette tips so that residual air bubbles are driven out.
