Evaluation of Root pH Change Through Gel Containing pH-sensitive Indicator Bromocresol Purple (CAT#: STEM-PPA-0045-LJX)

Name: Evaluation of Root pH Change Through Gel Containing pH-sensitive Indicator Bromocresol Purple
SKU: STEM-PPA-0045-LJX
Rating: 5 (1 reviews)

Introduction

The Rapid Alkalinization Factor (RALF) is a plant hormone peptide that inhibits proton transport causing alkalinization of the extracellular media. To detect the alkalinization response elicited by RALF peptides in root cells, Arabidopsis seedlings are carefully transferred to a gel containing the pH-sensitive indicator bromocresol purple, treated with the peptide and photographed after 30 min.

Principle Applications Procedure Materials Notes

Principle

Acid-base indicators produce different colors in aqueous solutions of their specific pH range. The indicator is added to the standard buffer solution, and the resulting color is used as the standard colorimetric tube. The pH value of the water sample can be measured by visual colorimetric comparison with the water sample colorimetric tube with the same indicator.

Applications

For determining the approximate PH value of solutions in food production, wastewater treatment, pharmaceutical and chemical industries

Procedure

1. Add ph indicator to the standard solution, and the solution with different pH will show different colors. Use these solutions as standard colorimetric tubes
2. Add the same ph indicator to the solution to be tested, and compare the color of the solution to be tested with the standard colorimetric tube to determine the approximate ph value of the solution
