Check if the same lab product or an alternative is used in the 5 most similar protocols
Human bronchial epithelial BEAS-2B cells, transformed by adenovirus, were purchased from American Type Culture Collection (Rockville, MD, USA). Epithelial cells were cultured with DMEM/F12 medium supplemented with 100 international units of penicillin, 100 μg/mL streptomycin, 2 μg/mL of amphotericin B, and heat-inactivated 10% fetal bovine serum (Invitrogen, Carlsbad, CA, USA) at 37 °C and 5% CO2. Cell suspensions at 5 × 104 cells/well were grown to 80% confluence for further studies.
To determine the cytotoxic effects of ASD, BEAS-2B cells were incubated with 0, 10, 100, or 500 μg/mL of ASD for 72 h. Cell cytotoxicity was determined using a CellTiter-96® aqueous one solution cell proliferation assay kit (Promega, Madison, WI, USA). For this assay, tetrazolium compound and phenazine etho-sulfate were added to each well and incubated for 4 h at 37 °C in a 5% CO2 chamber. Color intensities were assessed using a microplate reader at wavelength of 490 nm. The cytotoxic effects of KRG (0 to 500 μg/mL) and Rg3 (0 to 1000 μg/mL) were also determined using a CellTiter-96® aqueous one solution cell proliferation assay kit (Promega).

To measure AR-mediated cell proliferation, 10,000 VCaP cells (AR positive prostate cancer cells) were plated in each well of a 96-well plate and incubated in steroid-free assay medium for 12 hours. After adherence, VCaP cells were treated with increasing concentrations of Zeta55, MDV3100 or SAHA together with 10 nM DHT for AR antagonist assays or without DHT for AR agonist assays. After 7 days, cell viability was measured using a CellTiter 96® AQueous One Solution Cell Proliferation Assay kit (Promega). 8,000 LNCaP cells, 5,000 DU145 cells (AR negative prostate cancer cells) or HEK293 cells (AR negative noncancerous cells) per well were cultured in DMEM with 10% FBS for 12 hours. After treatment with increasing concentrations of Zeta55, MDV3100 or SAHA for 3 days, the cell viability was measured using a CellTiter 96® AQueous One Solution Cell Proliferation Assay kit (Promega).

FACS Analysis of Cd-Induced Apoptosis and Cell Cycle

Check if the same lab product or an alternative is used in the 5 most similar protocols
Fluorescence-activated cell sorting (FACS) analysis was done to test the effect of Cd exposure on cell cycle distribution and apoptosis of all cell lines. Equal numbers of cells were seeded and cultured for 24 hours. Cells were then harvested, washed with cold PBS, and stained with propidium iodide (PI-A) and Annexin-V-FITC using FITC-ANNEXIN V-PI-A KIT (BD Biosciences) for apoptosis and nuclear stain 4′,6-diamidino-2-phenylindole (DAPI) (BD Biosciences) for cell cycle analysis according to the manufacturer’s protocol. Stained cells were immediately analyzed by FACS (BD FACSVerse; BD Biosciences). Cell viability/proliferation was determined by using the CellTiter 96 AQueous One Solution Cell Proliferation Assay kit (Promega, Madison, WI) according to the manufacturer’s protocol. For cell viability assay, cells were seeded in 96-well microplates at a density of 5×103 cells per well. After 24 hours of culture, cell viability was determined by adding 20ul/well of the CellTiter 96 AQueous One Solution Cell Proliferation Assay kit (Promega, Madison, WI) according to the manufacturer’s protocol. Absorbance at 490 nm was measured with a kinetic microplate reader (Spectra MAX 190; Molecular Devices Co., Sunnyvale, CA).

Cell Proliferation Assay Protocol

Cells were seeded at 1 × 104 cells/well in 96-well plates in 200 μL medium and left to adhere overnight. The following afternoon, media was replaced with media containing 0.5% FCS and incubated overnight once more. After each timepoint, cell proliferation assays were carried out using the Promega CellTiter 96® Aqueous One Solution Cell Proliferation Assay kit (Promega, Southampton, UK) following the manufacturer’s instructions. Spent media was removed from all wells, followed by addition of 100 μL of 0.5% FCS-containing media and 20 μL of CellTiter 96® Aqueous One Solution Reagent. The plate was then incubated at 37 °C with 5% CO2 for 4 h. Absorbance was read at 490nm using a GloMax® Discover Microplate Reader (Promega, UK).

For cell viability analysis, an MTS assay was performed using the Promega CellTiter 96 AQueous One Solution Cell Proliferation Assay kit (Promega Corporation, Wisconsin, USA) based on the manufacturer's instructions. Briefly, 50 μl of MTS reagent was added to the respective Ramos lymphoma cell medium (500 μl) and incubated for about 4 hr at 37°C in a 5% CO2 in air atmosphere. Absorbance reading at 490 nm using a spectrophotometer ELISA reader was taken (mQuant; BioTek, Winooski, VT, USA).

Cell Proliferation Assay with Glutamine

Check if the same lab product or an alternative is used in the 5 most similar protocols
We typically plated 0.5 million cells per 10-cm dish in duplicate in culture medium without glutamine and with dialyzed fetal bovine serum (glutamine-free medium), with glutamine and with dialyzed fetal bovine serum (glutamine-containing medium), and with glutamine and regular fetal bovine serum (complete medium). We added the test compounds at the same time as the trypsinized cells were plated on the dishes. We examined the cultures under microscope, and stained with crystal violet when appropriate. If a treatment had an effect, we waited for the surviving cells to yield colonies (approximately 3 weeks) before staining and photographing or scanning stained dishes. To determine whether a test compound had any effect on cell growth in actively proliferating cells, we performed a similar experiment in a 96-well format and determined relative cell proliferation with MTS assay using CellTiter 96® AQueous One Solution Cell Proliferation Assay kit (Promega Corporation, Madison, WI).

Comparing NF1+ and NF1KD Cell Growth

Check if the same lab product or an alternative is used in the 5 most similar protocols
To compare cell growth between NF1+ and NF1KD cells, cells stably expressing NF1 shRNA were first seeded in estrogen-deprived medium, typically in triplicate, with DOX added at the same time. Two days later (Day-0), the medium was replaced with a fresh medium containing either vehicle control or compound(s) under investigation, with medium change every three days thereafter. The number of viable cells was measured using the CellTiter 96 Aqueous One Solution Cell Proliferation Assay kit (Promega) six days later (Day-6). Cell growth between parental and NF1 knock-out cells was similarly examined except no DOX was added. Apoptosis was measured by FITC-Annexin (Becton Dickinson) staining followed by FACS.

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.
