Adp glo reagent

Manufactured by Promega
Sourced in United States, United Kingdom

The ADP-Glo reagent is a laboratory product designed to detect and quantify the presence of ADP (Adenosine Diphosphate) in a sample. It functions by converting ADP into ATP (Adenosine Triphosphate), which is then measured using a luminescent assay. The core purpose of the ADP-Glo reagent is to provide a sensitive and reliable method for the analysis of ADP levels in various experimental settings.

Kinetic analyses of FLT3-ITD were performed using a luminometric kinase assay varying the concentration of ATP using the ADP-Glo reagents (Promega). The serially diluted A674563 and FLT3-ITD (40 ng/μL) were assayed in a reaction (10 μL) containing 40 mM Tris (pH 7.6), 20 mM MgCl2, 2 mM MnCl2, 50 μM DTT. After 60 min incubation at RT, various concentrations of ATP, 0.2 μg/μL FLT3 substrate Poly (4:1 Glu, Tyr) peptide added and incubated for 60 min at 37°C. The overall rate of reaction is determined as the slope of the decreasing phase of the reaction. Each data point was collected in duplicate and kinetic parameters were obtained using Prism 5.0 (GraphPad Software, San Diego, CA).

SIRK1-GFP and QSK1-GFP fusion proteins were affinity purified over anti-GFP beads (see above). A luciferase-based kinase activity assay was performed as described (36 (link)). The agarose beads with GFP-tagged proteins were re-suspended into 30 μl kinase reaction buffer with ATP and the generic kinase substrate myelin basic protein (40 mm Tris/HCl pH 7.5, 10 mm MgCl2, 0.1% BSA, 2 mm DTT, 100 μm ATP, 0.4 μg/μl myelin basic protein). After incubation for one hour, 30 μl ADP-GLO Reagents (Promega, Mannheim, Germany) was added and incubated for 40 min. Then Kinase Detection Reagents were added and incubated for another hour. Luminescence as a measure of ATP conversion from ADP was recorded with a luminometer (Tecan M200 Pro, Crailsheim, Germany). In general, protein isolations from three independent batches of roots were tested, and the average activity value is presented.

Optimal Reaction Time for PERK Kinase Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
To determine the optimal reaction time, 87 nM of PERK reacted with 50 μM of ATP and 0.26 μM of SMAD3, in presence of 0.87 μM of GSK2606414 (inhibition curve) or calcineurin-B (activation curve), or kinase buffer A (basal curve). Similar to previous experiments, all solutions were prepared in kinase buffer A, at a final reaction volume of 5 μL, and run in white 384-well microplates (Greiner), in triplicates. The kinase reaction was terminated at different time-points—15, 30, 60, and 120 min—by adding 5 μL of ADP-Glo reagent (Promega) and incubating for 40 min at RT. The ATP consumption was measured on a FLUOstar® Omega plate reader (BMG LabTech), after a 40 min incubation with 10 μL of kinase detection reagent (Promega), at RT, protected from light. After correcting the background as before, data was normalized to PERK basal activity (i.e., condition where neither GSK2606414 nor calcineurin-B were added), in order to calculate the percentage of relative PERK activity. The GSK2606414 (inhibition) and calcineurin-B (activation) curves were obtained by plotting the percentage of relative PERK activity against the respective time-point.

RIPK2 Kinase Inhibition Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
Recombinant RIPK2 protein (20 ng per reaction) is diluted in the reaction buffer consisting of 40 mM Tris (pH 7.5); 20 mM MgCl2; 0.1 mg/ml BSA; 50 μM DTT. Diluted protein is added to low volume white 384 well plates (2 μL/well). Inhibitors are diluted in reaction buffer (final 25% DMSO), 1 μL is added to each well and incubated 5 min at room temperature. Reactions are initiated by the addition of 2 μL of 100 μM ATP and 1 mg/ml RS repeat peptide (SignalChem) in the reaction buffer. Plates are sealed with plastic coverslips and incubated at room temperature for 2 h. Reactions are stopped by the addition of 5 μL of ADPGlo reagent (Promega) and ADP generation reaction is performed for 40 min at room temperature. Luminescence signal is generated by the addition of 10 μL of Kinase detection reagent (Promega) for 30 min at room temperature. Luminescence signals are determined using appropriate luminescence plate-reader (typical integration time 0.3-1 sec). To calculate percent inhibition, average background signal is subtracted from test well and maximal signal wells. Inhibition, % = (1- (test signal/maximal signal))*100. The percent inhibition at a specified concentration is determined or IC50 values are calculated based on a dose range of inhibitor concentrations using non-linear regression in GraphPad Prism software.

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.
