Check if the same lab product or an alternative is used in the 5 most similar protocols
The cytotoxic effects of resveratrol (1.56-100 μM), doxorubicin (0.01-0.92µM) and their combination were analyzed in HUVECs by ATP assay kit (ATP Bioluminescent Somatic Cell Assay Kit; Sigma, Steinheim, Germany). Briefly, HUVECs were seeded at a density of 5×10 3 cells per well of 96-well plates in triplicate. The cells were treated with resveratrol (1.56-100 μM concentration), doxorubicin (0.01-0.92 µM) and their combinations for 48h. After 48h treatment, 150 μl of media was removed from each well and 50 μl of somatic cell ATP-releasing agent (ATP Bioluminescent Somatic Cell Assay Kit; Sigma, Steinheim, Germany) was added. The plate was well agitated and allowed to stand for 30 min at room temperature. At the end of the incubation, 50 μl of a mixture from each well was transferred to a white non-translucent plate. 50 μl of ATP Assay Mix (ATP Bioluminescent Somatic Cell Assay Kit, Sigma, Steinheim, Germany) was added to each well and the emitted light was measured using a 96-well Microplate Luminometer (Bio-Tek, Winooski, VT, USA). ATP viability assay was performed at least twice and the results are given as mean±SD of independent experiments.

Blastocyst ATP Quantification Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Individual blastocysts obtained from control, lipid-free and lipid-rich RN treatments were collected in 10 µL of PBS + 0.01% PVP and frozen at −80°C. ATP concentrations were determined by the ATP bioluminescent somatic cell assay kit (Sigma Chemical Co.) as previously described with minor modifications (Cukurcam et al. 2004 (link), Simsek-Duran et al. 2013 (link), Silva et al. 2015 (link)). Briefly, 1:5 diluted ATP assay mix was added to individual wells in an opaque 96-well plate. In a separate tube, somatic cell ATP-releasing reagent was mixed with each sample or standards, and added to the assay mix. The amount of light emitted was immediately measured using a Synergy 2 plate reader for luminescence (BioTek). ATP concentration was calculated by comparison to a standard curve ranging from 60 fmol to 2 pmol/100 µL and normalized (per cell) using the average total cell number for blastocysts from each treatment.

The intracellular ATP was quantified by using an ATP bioluminescent somatic cell assay kit (Sigma-Aldrich). Briefly, mutant epimastigotes (107 parasites per tube, 0.1 ml) were incubated in a solution containing 100 mM sucrose, 50 mM KCl, and 50 mM Tris–HCl (pH 7.2 adjusted with HCl). Cellular extracts were prepared by mixing 0.1 ml epimastigotes with 0.1 ml somatic cell ATP releasing reagent and the mixture was left on ice for 1 min. Half of the cellular extract (0.1 ml) was transferred to MTS-11C minitubes (Axygen, Union City, CA, USA) containing 0.1 ml ATP assay mix and stirred for 10 s at room temperature. The total amount of light emitted was measured with a GloMax Multi JR detection system (Promega, Madison, WI, USA). Total intracellular ATP concentration per cell number was calculated using a standard ATP curve, prepared, and analyzed in each experiment (Carvalho-Kelly et al., 2020 (link)).

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.
