Ponceau S is a synthetic red dye commonly used as a protein stain in biological and biochemical laboratories. It binds to blotted proteins on membranes (such as nitrocellulose or PVDF) and allows rapid visualization of protein bands.

Thymolphthalein Complexone, also known as Thymolphthalexone, is a complexometric indicator and is more than just a simple pH indicator. It is particularly known for its ability to chelate (bind with) certain metal ions, which is its primary function in analytical chemistry.

Titan Yellow (also called Thiazole Yellow G or Clayton Yellow) is a thiocarbamide azo dye commonly supplied as a 65% dye content grade for laboratory and industrial use. It is widely used as a stain, adsorption reagent, and complexometric indicator due to its strong affinity for certain metal ions.

Toluidine Blue O (TBO) is a cationic thiazine dye widely used as a biological stain and indicator. It is particularly valuable in histology, cytology, and microbiology because of its ability to differentially stain acidic tissue components and exhibit metachromasia (color shift depending on the chemical environment).
