Collection: Plasma and Blood Proteins

Plasma and Blood Proteins — covers porphyrin compounds and cobalamin derivatives involved in oxygen transport and heme and vitamin B12 metabolism, including bile pigments, chlorophyllin, and substituted forms of vitamin B12. This group serves as a structural reference for biochemical studies of pigments and metal cofactors in biological systems.

Plasma and Blood Proteins is used as an analytical standard in heme metabolism research, bilirubin measurement, and studies of cobalamin biosynthesis pathways in biochemistry laboratories. Compounds such as hemin and hydroxocobalamin are also used as metal cofactor models in enzyme research and bioinorganic chemistry by biochemistry and pharmaceutical researchers.

Example products in this collection: TCI B0460 635-65-4 Bilirubin, TCI C0052 9001-05-2 Catalase from Bovine Liver, TCI S0271 Sodium Copper Chlorophyllin, TCI C0449 68-19-9 Vitamin B12, TCI M2742 288315-09-3 Methylcobalamin Hydrate, TCI H0008 16009-13-5 Hemin, TCI H1542 22465-48-1 Hydroxocobalamin Acetate.

Pay attention to the hydrate or anhydrous form, the counter-cation (acetate, chloride), and the purity level, which affect the stability of porphyrin compounds during storage and analytical use. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
