Web1 Oct 2024 · In general, FDA assay is usually used for image analysis based on fluorescence microscopy and the green fluorescence represents the viable cell. Intracellularly, FDA can be detected spectroscopically by measuring its fluorescence (λex 405 or 485 nm, λem 520 nm) or absorbance ( λmax 490 nm) [52]. WebBiofilm viability was determined using a double live/dead staining kit (BacLight Bacterial Viability Kits [Invitrogen Molecular Probes]; Life Technologies, Carlsbad, CA, USA) containing nucleic acid stains SYTO 9 and propidium iodide (PI). The biofilm formation assay described above was performed with minor changes. WebThis kit uses Selenocystine as a Cystine Analog (CA) and can measure the cystine uptake ability of cells by a plate reader in a short time.
