3,3',5,5'-Tetramethylbenzidine（TMB）(Biological level) Appearance:white crystal powder Purity:≥99% ;Molecular formula:C16H20N2 ;Molecular wt:240.35 Melting point:169-170οC ;CAS No:54827-17-7 ;Prod No.:TC-001 ; Producing Area:Luoyang China The performance and application of TMB: 3,3',5,5'-Tetramethylbenzidine(TMB) is a new-type safe color primary reagent.Compared with some traditional color primary reagents such as benzidine, o-tolidine and o-diaminobenzene,the merits of TMB are high sensitive detection and excellent stability. And as a result of zoopery and Ames which is to experiment on self-acting variability of bacteria,showing that TMB is a kind of non-cancerogen and non-mutagen ,and can be used safely. Currently,TMB is taking the place of benzidine which is a strong cancerogen and other ramifications of benzidine which are carcinogenic step by step.TMB can be applied in areas like clinical assay, forensic analysis, criminal investigation and environmental detection,etc.As a new zymolyte of peroxidase,TMB has wide applications in enzyme immunoassay (EIA) and enzyme-linked-immunosorbent serologic assay (ELISA). The main items of TMB’s applications are: 1. making up test paper of uranalysis; 2. detection of hepatitis virus; 3. detection of gravidity; 4. rapid determination of glucose,hemoglobin and albumin in blood and urine; 5. occult blood test of excrement; 6. to detect the value of granulocyte in blood; 7. detection of steroid and sex hormone; 8. determination of enzyme activity; 9. analysis and detection of antigen, antibody and germ plasm; 10. rapid determination of alcoholicity in saliva; 11. pigmentation of biological specimen; 12. quality test of water and detection of fingerprint rendering; 13. detection of AIDS virus. Properties of TMB: White / primrose yellow crystalline powder, odourlessness and tastelessness. Difficult to dissolve in the water, but easy to dissolve in the organic solvents such as acetone, aether, dimethylsulphoxide and dimethylformamide, etc.
