CaF2: An Ideal Substrate Material for Infrared Spectroscopy?
2020年5月27日 · CaF 2 seems to be the ideal substrate material for the infrared spectroscopy of organic and biological layers, since its refractive index is very similar to that of these materials. As a consequence of this similarity, the baseline, i.e., the signal strength in nonabsorbing regions, is nearly flat and does not show notable interference fringes.

2022年9月1日 · Here, we demonstrate that Cdr1p localizes in the lipid rafts of both the C. albicans WT and ergosterol deficient (erg11Δ/Δ) strains using a novel spot variation fluorescence correlation spectroscopy (svFCS) technique [10], which was confirmed by the analysis using Optiprep tm and Western Blot.
Spatial Transcriptomic and Metabolomic Landscapes of Oral …
The immune cell membrane molecule CMKLR1, after interacting with RARRES2, a receptor on the surface of CAF2 cells, activates lipid metabolism in CAF2 cells, resulting in the accumulation of large amounts of lipid-associated metabolites in the mesenchymal area of fibroblast aggregates and the OSF area.

2020年1月10日 · Sterols (μg/mg dry mass of isolated plasma membrane lipids, mean ± SD, n = 3) in Candida albicans CAF2‐1 and CAF4‐2 strains grown in the following conditions: control without antimicrobial agents, Flc—treated with fluconazole 4 μg/ml, Gent—treated with gentamicin 256 μg/ml, Flc + Gent—simultaneously treated with fluconazole 4 μg ...
Membrane-specific and calcium-dependent binding of the
2024年2月15日 · Membrane binding of the protein CaLB is analysed by ATR-FTIR spectroscopy. Use of biomimetic membranes reveal increased affinity to PI (3)P lipids. Binding affinity is calcium-dependent. Higher calcium concentration increases binding affinity. Only minor conformational changes occur upon binding.
The complex nature of calcium cation interactions with …
2016年12月1日 · We demonstrate that lipid membranes have substantial calcium-binding capacity, with several types of binding sites present. Significantly, the binding mode depends on calcium concentration with...
Formation of the CRS2-CAF2 Group II Intron Splicing Complex Is …
In this work we show that the CRS2-CAF complexes are stable in the absence of their intron targets and that CRS2 binds a 22 amino acid motif in the COOH-terminal region of CAF2 that is conserved in CAF1.
