Million's Reagent (Test Of Proteins)
Million's Reagent (Test Of Proteins) (Product Code: SCL403/0111) is the protein-test reagent more commonly spelled Millon's reagent, used to detect tyrosine-containing proteins in school and college biology practicals. Supplied as an analytical reagent in a 125 ml pack, it gives senior secondary and college students a second, more specific protein test to set beside the biuret test. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, with an MSDS.

What Is Millon's Reagent Used For?
A few drops of the reagent are added to a small volume of protein solution, such as diluted egg white or milk, in a test tube. A precipitate forms, and on gentle warming it turns red, confirming a tyrosine-containing protein. Comparing egg albumin with gelatin, which contains very little tyrosine and reacts only weakly, helps students see that different protein tests detect different chemical features. Because only a few drops are needed per tube, one pack covers many practical groups, making it a sensible addition to the biology lab equipment schools in India use for biomolecule tests.
Millon's-type reagents are traditionally prepared from heavy-metal salts in acid, so check the MSDS supplied with this pack for its composition, hazards and disposal advice. The heating step is best done by the teacher or in a chemical fume cupboard, with goggles and gloves, and all used tube contents should be collected in a labelled waste container rather than poured down the sink.
Supplier
This reagent is supplied by Jain Scientific Equipments Private Limited, which is known in the market as ScienceLab.

Frequently Asked Questions
Is Million's Reagent (Test Of Proteins) the same as Millon's reagent?
Yes. Million's Reagent (Test Of Proteins) is the reagent used in Millon's test for proteins; "Million's" is simply the spelling used in the product name on this site, and enquiries under either spelling refer to the same item.
What does a positive result with Million's Reagent (Test Of Proteins) look like?
With Million's Reagent (Test Of Proteins), a precipitate that turns red on gentle warming indicates a protein containing tyrosine. No red colour means tyrosine is absent or present only in traces, as with gelatin compared with egg albumin.
How is Million's Reagent (Test Of Proteins) different from the biuret test?
The biuret test responds to the peptide bonds present in all proteins, while Million's Reagent (Test Of Proteins) responds specifically to the amino acid tyrosine. Running both tests side by side gives students a fuller picture of a protein sample.
How much reagent is in one pack of Million's Reagent (Test Of Proteins)?
Each pack of Million's Reagent (Test Of Proteins) holds 125 ml of analytical reagent grade reagent and includes an MSDS. Only a few drops are needed per test tube, so one pack covers many practical groups.
What is the shelf life of Million's Reagent (Test Of Proteins)?
The shelf life of Million's Reagent (Test Of Proteins) depends on the chemical, its grade and storage conditions, so no fixed period is quoted. Ask us for the expiry date of the batch you are quoted, and store the bottle as the MSDS directs.
How should used Million's Reagent (Test Of Proteins) be disposed of?
Collect all used Million's Reagent (Test Of Proteins) and tube contents in a labelled waste container, and dispose of them according to the MSDS and local rules for hazardous chemical waste. Never pour the reagent or its reaction mixtures into the drain.
Who supplies Million's Reagent (Test Of Proteins)?
Million's Reagent (Test Of Proteins) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. It can be quoted together with other biomolecule test reagents under code SCL403/0111; transport arrangements for hazardous reagents are confirmed per order.
