2, 6-dichlorophenolindophenol ( DCPIP ) is a blue chemical compound used as a redox dye. In Oxidized form DCPIP is blue;whereas in reduced form DCPIP is colorless.The rate of photosynthesis can be measured by the rate at which this dye changes color (is reduced) when exposed to light in a photosynthetic system. This reaction is reversible, as colorless DCPIP can be reoxidized to blue. Blue redox indicator dye used for the determination of Vitamin C (ascorbic acid), which when Vitamin C is present reduces to a colorless hydroxy compound. May be used as an electron acceptor and to stain glutathione reductase electrophoresis gels. Also known as Tillman's reagent.

Applications:

2, 6-dichlorophenolindophenol (DCPIP) is used as a substitute for NADP+. The dye changes color when it is reduced, due to its chemical structure. The rate of photosynthesis light-dependent reaction can be measured with this property of DCPIP, because one of the stages of the light reaction is an electron transport chain that normally ends with the reduction of NADP+. When DCPIP is present, it also gets reduced by the light reaction. The amount of DCPIP reduced can be found by measuring the solution's light transmittance with a spectrophotometer. 2, 6-dichlorophenolindophenol sodium salt is a redox dye commonly used as a monitor of the light reactions in photosynthesis because it is an electron acceptor that is blue when oxidized and colorless when reduced. It is part of the Hill reagents family. DCPIP can also be used as an indicator for Vitamin C. If vitamin C, which is a good reducing agent, is present, the blue dye, which turns pink in acid conditions, is reduced to a colorless compound by ascorbic acid. 2, 6-Dichloroindophenol sodium salt hydrate is suitable for vitamin C determination. It acts as a redox dye to investigate the efficiency of gold nanoparticles (Au-NP) for the enzymatic activity of glucose oxidase. It is also used to compose UVB specific dosimeter and to measure the rate of photosynthesis. It serves as a good reducing agent.

RBFZWTMVVUVHLM-UHFFFAOYSA-M

Water soluble pH indicator used in the 6.8 (yellow) to 8.2 (red) range. Commonly employed as a cell tissue culture pH marker. Under normal conditions, phenol red added to the growth medium will have a pink-red color. Dying cells or overgrowth of contaminants will cause a change in pH resulting in a change in indicator color.

Solubility

Soluble in water yielding a dark red solution (25 mg/ml), alcohol (4 mg/ml), methanol, ethanol (200 mg/ml), and aqueous alkali hydroxides or carbonates with formation of a red colored solution.

• Storage :Store at room temperature
• pK: 7.9

Applications

It is commonly employed in cell biology laboratories as a cell tissue culture pH marker. Under normal conditions, phenol red added to the growth medium will have a pink-red color. Usually 15 mg/l is used to produce this effect. If problems arise, such as dying cells or overgrowth of contaminants, this will cause a change in pH resulting in a change in indicator color. This color change is an indication that the medium needs to be replaced. Additionally, Phenol Red could potentially be useful as a differentiation factor.Phenol red in tissue culture media can act as a weak estrogen, especially with human breast cancer cells. Phenol red can be used to measure hydrogen peroxide in supernatants from cultured macrophages in multiwell plates.Phenol Red sodium salt commonly employed in cell biology laboratories as a cell tissue culture pH marker.

Cresyl Violet Acetate is a certified solid dye used for the preparation of a staining solution to demonstrate the presence of Nissl substances in neurons and cell nuclei. Is a metachromatic basic dye for the demonstration of Nissl substance and nuclei in nerve tissue. As a working solution, Cresyl Violet Acetate can be utilized in the Luxol Fast Blue (LFB) procedure or used solely as a stand-alone nerve tissue stain. Cresyl Violet acetate is used as stain for nerve cells and tissue spinal cord section, brain paraffin, cells and granules. It is also useful to measure pyruvate dehydrogenase complex activity when its acetylation is coupled with acetyl-CoA production.

Applications:

It is also often used as a counterstain to Luxol Fast Blue. Cresyl violet acetate is used for staining nerve tissue and nerve cells and fresh tumor tissue for biopsy. Product Description. Cresyl violet acetate is a high purity biological stain to used for Nissl staining of spinal cord and brain paraffin sections and to stain mast cell and cartilage granules. Cresyl Violet acetate is used in Nissl staining of brain paraffin and spinal cord section. It is also certified for use to stain mast cell and cartilage granules. It has allowed the visualization of the arterial blood supply to the central hemispheres when dissolved in isotonic saline and DMSO.

m-Cresol Purple is a pH indicator dye used primarily in spectrophotometric pH measurement. It operates in the pH ranges 1.2 - 2.8 (red to yellow) and 7.4 - 9.0 (yellow to violet). Further, it is employed to stain epithelial cells and proteins.A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. The m-Cresol purple molecule contains a total of 48 bond(s). There are 30 non-H bond(s), 20 multiple bond(s), 2 rotatable bond(s), 2 double bond(s), 18 aromatic bond(s), 1 five-membered ring(s), 3 six-membered ring(s), 1 nine-membered ring(s), 2 aromatic hydroxyl(s) and 1 sulfonate(s) (thio-/dithio-).

Applications:

Accurate pH measurements in polar waters and sea ice brines require pH indicator dyes characterized at near-zero and below-zero temperatures and high salinities. We present experimentally determined physical and chemical characteristics of purified meta-Cresol Purple (mCP) pH indicator dye suitable for pH measurements in seawater and conservative seawater-derived brines at salinities (S) between 35 and 100 and temperatures (T) between their freezing point and 298.15 K (25 °C). Within this temperature and salinity range, using purified mCP and a novel thermostated spectrophotometric device, the pH on the total scale (pHT) can be calculated.m-Cresol Purple is a recommended indicator for open-ocean pH measurements. The compound is used in many colorimetric sensor studies.
