34487-61-1 Usage
Description
Phenol Red sodium salt is a water-soluble pH indicator that exhibits a color change within the pH range of 6.8 (yellow) to 8.2 (red). It is commonly used in cell biology laboratories as a cell tissue culture pH marker.
Uses
Used in Cell Biology Laboratories:
Phenol Red sodium salt is used as a cell tissue culture pH marker for monitoring the pH levels in growth media. Under normal conditions, the indicator will have a pink-red color, and a concentration of 15 mg/l is typically used to produce this effect. Changes in pH due to dying cells or overgrowth of contaminants will result in a color change, signaling the need to replace the medium. Additionally, Phenol Red may potentially serve as a differentiation factor.
Used in Zebrafish Embryo Microinjection:
Phenol Red sodium salt has been utilized as an indicator during single-guide RNA microinjection into one-cell stage zebrafish embryos, aiding in the visualization and monitoring of the microinjection process.
Used in Microfluidic Assays:
Phenol Red has been employed in the preparation of phosphate buffer saline (PBS) with phenol red for microfluidic assays, enabling the simultaneous culture of multiple cell types. This application allows for the study of cell interactions and responses in a controlled microenvironment.
Used in Horseradish Peroxidase-Phenol Red Assays:
Phenol Red has been utilized in horseradish peroxidase-phenol red (HRP-PR) H2O2 (hydrogen peroxide) detection assays to identify redox cycling compounds. This application leverages the color change properties of Phenol Red to detect the presence of reactive oxygen species and assess the redox activity of compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 34487-61-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,4,8 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34487-61:
(7*3)+(6*4)+(5*4)+(4*8)+(3*7)+(2*6)+(1*1)=131
131 % 10 = 1
So 34487-61-1 is a valid CAS Registry Number.
