Atp determination kit

Manufactured by Promega
Sourced in United States

The ATP determination kit is a laboratory tool used to measure the concentration of adenosine triphosphate (ATP) in various samples. ATP is a crucial energy-carrying molecule found in all living cells. The kit provides reagents and protocols to quantify ATP levels, which can be used to assess cellular activity and energy metabolism.

ATP was measured with a ATP determination kit (Molecular Probes), following the instructions of the manufacturer28 (link). Cells were lysed with 1× Passive Lysis Buffer (Promega) and were diluted 1:10 using the ATP determination kit reactant mix leading to a total volume of 100 μl. Luminescence was determined directly after the addition of the lysate to the reaction, and was quantified in a Luminometer (Turner Designs, Sunnyvale, CA). ATP concentrations in experimental samples were calculated by using an ATP standard curve.

Quantifying Cellular ATP Levels

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cellular ATP was quantified using an ATP determination kit according to the manufacturer's instructions (Promega, San Luis Obispo, CA, USA). Briefly, cells, which had been plated at equal densities, were lysed in passive lysis buffer. Equal volumes of cell lysate were then added to the standard reaction solution, and luminescence was measured and normalized to the protein amount of each lysate.

ATP was assessed using ATP determination kit (Invitrogen) according to manufacturer instruction. HUVECs were harvested and counted, then lysed in H2O (1 ml/1 × 106 cells) and boiled for 10 min. After spinning, the supernatants were assessed with the ATP determination kit, and luciferase activity was measured by Glomax luminometer (Promega, Madison, WI).

Calreticulin (CRT) exposure. LL/2 and MC-38 cells were seeded in duplicate onto 6 well plates at 5×105 cells/well. LL/2 cells were treated in triplicates with EV-LL/2 (10 particles/cell), EV-MC-38 (10 particles/cell), Virus (10vp/cell), EV-Virus-LL/2 (10 particles/cell), EV-Virus-MC-38 (10 particles/cell). MC-38 cells were treated in triplicates with EV-MC-38 (10 particles/cell), EV-LL/2 (10 particles/cell), Virus (10vp/cell), EV-Virus-MC-38 (10 particles/cell), EV-Virus-LL/2 (10 particles/cell). After 24 h cells were harvested and stained with 1:1000 diluted rabbit polyclonal anti-Calreticulin antibody (Abcam, Cambridge, UK) for 40 min at 4°C subsequently with 1:100 diluted Alexa-Fluor 488 secondary antibody (Invitrogen, Carlsbad, CA) and analyzed by flow cytometry (LSR II, BD, Franklin Lakes, NJ).
ATP release. LL/2 and MC-38 cell lines were seeded in triplicates onto 96 well plates at 1×104 cells/well and treated as mentioned above. Supernatants were collected after 48 h and analyzed with ATP Determination Kit according to manufacturer's protocol (Promega, Madison, WI) for luminometric analysis (Varioscan Flash, ThermoFisher Scientific, Waltham, MA).

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.
