ATP | 2x 250mM, pH 7.4

Product name

ATP, Synonyms: Adenosine 5′-triphosphate,  ATP disodium salt

Product description

Adenosine 5′-triphosphate (ATP) is a central component of energy storage and metabolism in vivo. Proteins like actin and myosin have a functional ATPase activity.
ATP 250mM is pre-adjusted to pH 7.4 upon the addition of 1ml ultrapure water. Addition of the ATP solution thus keeps the pH of the solution stable and does not rapidly decrease the pH as pure ATP powder does. Hence the additional adjustment of the buffer pH is not necessary.     

Overview

Suited to supplement all buffers and solutions buffered at ~pH 7.4.

Form

Lyophilized, ready-to-use.

Quantity

Powder: 2x 250mM ATP, 5.0mM Tris-Cl, pH 7.4 (sterile filtered before freeze-drying). Add 1.0ml of ultrapure H₂O to each tube to obtain a fresh 250mM stock solution, suited e.g. to make 250ml buffer with a final concentration of 1mM ATP. 

Formula

Empirical Formula (Hill Notation) C₁₀H₁₄N₅Na₂O₁₃P₃ • xH₂O; Molecular Weight 551.14 (anhydrous basis)

Purity

Ultrapure reagents.
