Lysosomal Signal Detection in HAoEC

Check if the same lab product or an alternative is used in the 5 most similar protocols
HAoEC were grown to confluence and treated as indicated. For detection of pH-dependent lysosomal signal, HAoEC were incubated with LysoID Green detection kit (ENZ51034; EnzoLife Sciences, USA) as recommended by the manufacturer and detached from surfaces using the PromoCell split kit. For flow cytometry-based quantification, cells were washed after the incubation and analysed immediately using the LSR Fortessa (BD Bioscience, USA). Data were analysed using FlowJo software (FlowJo9/10, LLC, Ashland, Ore).
For imaging of LysoID, cells were washed after incubation and carefully covered with a glass cover slip and imaged immediately (Echo Revolve Microscope) with the same exposure time throughout each imaging experiment.

Quantifying Acidic Vesicles in Live Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Acidic vesicles were detected in live cells using the Lyso-ID Green detection kit (Enzo Lifesciences, Farmingdale, NY, USA). Cells were seeded in 12 well plates (90% confluent) and incubated with 4 µl/ml Lyso-ID in assay buffer at 37 °C for 30 minutes. Cells were washed with assay buffer and fluorescence measured on a plate reader at excitation 488 nm, emission 520 nm. Following reading, buffer was aspirated, cells lysed overnight in 0.25 M NaOH and protein concentration measured. Cell fluorescence was expressed as fluorescent units/mg protein.

Measuring Lysosome Formation Induced by MG

Check if the same lab product or an alternative is used in the 5 most similar protocols
Lysosome formation induced by MG was measured using the LYSO-ID® Green Detection Kit (ENZ-51034, Enzo). 2.4×105 cells were seeded into each well of six-well plates and cultured in a CO2 incubator at 37°C overnight. MG or the vehicle were used to treat the cells for 24 h, and the cells were harvested and stained with fluorescent dyes using the LYSO-ID® Green Detection Kit as described by the manufacturer’s. Fluorescence intensity was measured using the NucleoCounter® NC-3000TM system (ChemoMetec) [37 (link)].

Lysosome Detection in Hypoxia

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were plated on 8-well coverglass slide (Sarstedt, Germany Cat.n° 94 6190802) and treated with LPS under normoxic or hypoxic conditions. For Baf A1 and CQ treatment, the compounds were added at a concentration of 100 nM and 100 µM, respectively, 6 h before the end of the experiment. After 24 h, cells were labeled by Lyso-ID Green Detection Kit (Enzo Life Sciences, Plymouth Meeting, PA, USA), and nuclear staining was performed by using DAPI. Cells were analyzed by confocal microscope and the fluorescence intensity was determined by ImageJ software, as described above.

ANE-induced lysosome formation was measured by a LYSO-ID® Green detection kit (ENZ-51034, Enzo). The dye accumulates in acidic compartments, such as endosomes, lysosomes, and secretory vesicles. Briefly, cells (2.4×105) were seeded in six-well plates overnight and then treated with the ANE or vehicle for 48 h. Cells were then harvested and stained with fluorescent dyes from a LYSO-ID® Green detection kit and measured using the NucleoCounter® NC-3000TM system (ChemoMetec).

Acidic vesicles were detected in live cells using the Lyso-ID Green detection kit (Enzo Lifesciences, Farmingdale, NY, USA). Cells were seeded in 96-well plates or 12 well plates (90% confluent) and incubated with 4 μl/ml Lyso-ID in assay buffer supplemented with 2% (v/v) FCS at 37 °C for 30 min. Cells were washed with assay buffer and fluorescence measured on a plate reader at excitation 488 nm, emission 520 nm. Following reading, the buffer was aspirated, cells lysed overnight in 0.25M NaOH and protein concentration measured. Cell fluorescence was expressed as fluorescent units/mg protein.
For live cell imaging, cells were seeded on glass bottom dishes (ibidi, Germany) and incubated with 1μl/ml Lyso-ID in HBSS for 15 min. Cells were then washed with HBSS and imaged in HBSS.

PG-induced lysosome formation was measured using the LYSO-ID Green detection kit (ENZ-51034, Enzo). The dye accumulates in acidic compartments, such as endosomes, lysosomes, and secretory vesicles. Briefly, 2.4×105 cells were seeded in six-well plates overnight. After treatment with 80 μg/ml PG or vehicle for 48 h, cells were then harvested and stained with fluorescent dyes using the LYSO-ID Green detection kit and measured using the NucleoCounter NC-3000 system (ChemoMetec).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
