Descripción

General description

Useful in the pH range of 7.0-9.0. Has a pK_a of 8.1 at 25°C.

Widely used as a biological buffer (absorbance: ≤0.03 at 260 nm; ≤0.02 at 280 nm). Useful in the pH range of 7.0-9.0. Has a pK_a of 8.1 at 25°C.

Application

• A Fast and Automated Melanin-bleaching Method for Histopathologic Evaluation of Pigmented Melanoma Tissues.: This study presents an automated melanin-bleaching technique using a Tris-based buffer to enhance histopathologic evaluation of pigmented melanoma tissues, aiding in more accurate diagnoses (Ugolini et al., 2022).


• Improvement of plant protein solubilization and 2-DE gel resolution through optimization of the concentration of Tris in the solubilization buffer.: Highlights the optimization of Tris concentration in solubilization buffers to enhance protein solubilization and gel electrophoresis resolution, crucial for biochemical studies (Cho et al., 2010).
