Descripciòn

Phenol red (Phenolsulfonephthalein) sodium salt is a pH indicator dye. Phenol Red sodium salt is also an antagonist of rat P2X1R. Phenol Red sodium salt enhances the halogenating activity of myeloperoxidase. Phenol Red sodium salt shows a distinct color change from pink to yellow in a positive pH reaction[1][2][3][4].

In Vitro

Guide (The following is our recommended protocol. This protocol is only a guide and should be modified according to your specific needs).
Phenol Red sodium salt acts as an indicator of AChE activity[4]
1.Solutions Preparation
Concentration of Phenol Red sodium salt in water is set to 500 µM.
2. Reaction
1) Thirty-five microliters of PBS, 25 µL of PBS 7.4 or tacrine solution, 20 µL of Phenol Red sodium salt, and 20 µL of 5 mM AChCl are consequently added to the surface of paper with immobilized AChE.
2) After 5 min of incubation, the surface of the paper is photographed using a smart phone camera placed on a 3D-printed, tube-shaped holder.
Note: in neutral pH of PBS 7.4, Phenol red gives a red color. After addition of AChCl, immediately forming acetic acid acidifying medium and the Phenol Red sodium salt turns yellow.

[1][2]

Phenol red is dissolved in 0.1% ethanol. To determine the effect of phenol red on cell proliferation, MCF-7 cells grown for 1 week before experiments in phenol red-free MEM supplemented are harvested and seeded into T-25 flasks (ca. 1.5 x 105 cells per flask). The following day, cells from three flasks are harvested and counted with a Coulter Counter. Then the medium is changed to phenol red- and insulin-free MEM, which contains various concentrations of dextran-coated charcoal-treated calf serum, phenol red (0-300 μM), tamoxifen, hydroxytamoxifen, estradiol, or ethanol vehicle (0.1%), and cell number is monitored as a function of time[1]. Phenol Red sodium salt is dissolved in distilled water as a 10 g/L stock solution[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
