Phenol Red (Sulfonphthal) is a pH indicator, red dye, and diagnostic aid for measurement of renal function. It is used also for researches of the gastrointestinal and other systems.

Ponceau S (Acid Red 112) is an azo protein dye commonly used as a stain in spot blotting assays for protein quantification.

Naphthoresorcinol (1,3-Dihydroxynaphthalene) is a fluorescent dye with an excitation wavelength (λex) of 330 nm and an emission wavelength (λem) of 380 nm.

MitoSOX Red is a fluorescent dye serving as a mitochondria-targeted fluorescent probe for superoxide, with cell membrane permeability and specificity. Upon oxidation, MitoSOX Red subsequently binds to nucleic acids within mitochondria/nuclei, producing intense red fluorescence, and is employed for detecting mitochondrial superoxide in live cells.

Nuclear Fast Red is an anthraquinone dye that serves as a red nuclear counterstain when aluminum ions are present in excess, thereby aiding in histological visualization of nuclear components. Nuclear Fast Red additionally functions as a histochemical and colorimetric reagent for calcium detection,Nuclear Fast Red further acts as a highly sensitive “off/on” fluorescent probe for the detection of guanine, making it a multifunctional research reagent.

MitoSOX Red TFA (Mito-hydroethidine TFA) is a fluorescent probe that specifically targets mitochondria in living cells.MitoSOX Red is susceptible to oxidation by superoxide, but is not easily oxidized by other ROS or RNS-generating systems.MitoSOX Red acts as a fluorescent indicator and can be used for live cell imaging.

Red-HyP-1 is a red dye that can be used for in vivo hypoxia imaging. The maximum emission maximum of Red-HyP-1 is 798 nm.

ATP-Red 1 is a fluorescent probe with good membrane permeability that selectively and rapidly responds to intracellular ATP concentrations in live cells.

Phenol Red sodium salt is a water-soluble pH indicator used in the range from 6.8 (yellow) to 8.2 (red).

C.I. Disperse Red 15 is a red dye. C.I. Disperse Red 15 is used as a fluorescent indicator.

Acridine red is an indicator of fluorescent.

D & C Red no. 31 is an agent of dye.

D&C Red No. 27 Aluminum Lake is a drug and cosmetic synthetic dye. The FDA lists it as a safe additive for drugs and cosmetics as per FDA standards.

DQ-BSA-RED is a red-fluorescent-labeled bovine serum albumin (BSA) derivative specifically designed for monitoring lysosomal proteolytic activity. DQ-BSA-RED can be used for live-cell imaging or for observation following formaldehyde fixation. DQ-BSA-RED exhibits excitation and emission maxima at 590 nm and 620 nm, respectively, and contains multiple dye moieties resulting in fluorescence self-quenching until proteolytic cleavage occurs within lysosomes, upon which bright fluorescence is emitted. DQ-BSA-RED therefore enables the visualization and quantification of lysosomal functionality in live-cell assays, while inactive lysosomes fail to generate fluorescence, providing a valuable tool for studying autophagy and intracellular degradation processes.

D & C Red no. 30 is an agent of red dye.

2-Hydroxy nile red trifluoromethanesulfonate is a fluorescent probe that can be incorporated into oligonucleotides as a nucleotide substitute. It serves as a DNA probe to detect polarity changes in the tumor microenvironment.

Perylene Red is a fluorescent dye.

Celltrack Deep Red is a fluorescent dye with a stable fluorescence signal that lasts for at least 72 hours. It is suitable for cell tracking and monitoring cell movement across multiple generations. Within a cell population, Celltrack Deep Red only transfers to daughter cells and does not transfer to adjacent cells (Ex/Em = 630/650 nm).

CytoTrace Red CMTPX is a cell-permeable, long-lasting cell tracer (Ex=577 nm, Em=602 nm).

Fluorescent Red Mega 485 NHS-ester is an amine-reactive fluorescent biolabel suitable for protein labeling.

Sudan Red 7B is a red non-fluorescent dye used for staining lipid bodies.

C.I. Acid Red 4 is a red dye.

ER-Tracker Red (solution) dye is a derivative of BODIPY dyes conjugated to Glibenclamide, exhibiting high selectivity for binding to the endoplasmic reticulum without toxicity to cells at low concentrations. This environmentally sensitive probe retains some fluorescence even after formaldehyde treatment and is characterized by high fluorescence lifetime and good extinction coefficients. Glibenclamide acts as an ATP-sensitive K+ channel blocker (Kir6, KATP) and CFTR Cl- channel blocker, binding within the endoplasmic reticulum. Note that ER-Tracker is not suitable for staining fixed cells. Ex/Em=587/615 nm.
