A microcrystalline silicon (μc-Si) layer is amalgamated with a-Si, forming a tandem membrane to form a micromorphous silicon. 2.4.5.4 A-Si/pc-Si tandem cell In addition, a-Si can be fused into a tandem cell with protocrystalline silicon (pc-Si). For high open-circuit voltage, pc-...
For example, covalent conjugation of peptides or Abs to the surface of therapeutic cells may affect membrane protein function and disturb relevant signaling patterns, leading to abnormal ligand-receptor binding and altered cell fate10. As a safe alternative, NPs have a history of successful ...
higher luminescence intensities: the highest activity was observed with the ArM2351 ⊂ Sav S112A. This highlights the importance of the “membrane permeability” and the “internalization” features of the cell-penetrating ArM. The cell viability, reflected by the SEAP activity, is essentially...
SUSD2 membrane staining was graded by two reviewers in a blinded, randomized fashion using the slides annotated for tumor presence. Staining intensity was graded as negative, weak, intermediate, or strong and received scores of 0, 1, 2, or 3 respectively. Percent tumor positivity coefficient ...
(See the drawing of a plant cell on page 435.) Plasma membrane. The plasma membrane of the cell is often described as selectively permeable. That term means that some substances are able to pass through the membrane but others are not. For example, the products formed by the breakdown ...

Schematic Drawing of Fluidic 219 Fluidic 219 Fluidic 219 Cross Flow Membrane Chips The cross-flow membrane chips have two in- and outlet ports above and below the membrane. This allows for experiments such as small molecule transfer measurements, on-chip dialysis or cell culture experiments. Upon...
Drawing on diverse aspects of cell biology and phylogenetic data, we invert the traditional interpretation of eukaryotic cell evolution. We propose that an ancestral prokaryotic cell, homologous to the modern-day nucleus, extruded membrane-bound blebs beyond its cell wall. These blebs functioned to fa...
(2 mM, in-house) for 30 min at 4 °C. Colonic crypts were subsequently plated in basement membrane extract (BME; Cultrex PC BME RGF type 2, Amsbio). Organoids were grown in human intestinal stem cell medium (HISCM), which is composed of Advanced Dulbecco’s modified Eagle ...
