Phenylalanine CAS:63-91-2 Manufacturer Supplier
Phenylalanie is an essential amino acid and it is the precursor of the amino acid tyrosine. The body cannot make phenylalanie but it needs phenylalanie to produce proteins. Thus, human needs to obtain phenylalanie from food. 3 forms of phenylalanie are found in the nature: D-phenylalanine, L-phenylalanine, and DL-phenylalanine. Among these three forms, L-phenylalanine is the natural form found in most foods that containing proteins, including beef, poultry, pork, fish, milk, yogurt, eggs, cheeses, soy products, and certain nuts and seeds.

3,3′,5,5′-Tetramethylbenzidine CAS:207738-08-7
3,3′,5,5′-Tetramethylbenzidine, also known as TMB, is a chemical compound commonly used as a chromogenic substrate in enzyme-linked immunosorbent assays (ELISA) and other biochemical assays. It is often used to detect and quantify the presence of enzymes such as horseradish peroxidase (HRP) in various biological samples. TMB undergoes a color change from colorless to blue in the presence of these enzymes. Subsequently, the reaction can be stopped by adding an acid which converts the blue color to a final yellow color. The intensity of the yellow color is proportional to the amount of enzyme present, allowing for quantification.
