Ninhydrin Sol (Test Of Amino Acids)
Ninhydrin Sol (Test Of Amino Acids) (Product Code: SCL404/0112) is a ninhydrin solution used to reveal amino acids in spot tests and on paper chromatograms in biology and biochemistry labs. Listed as analytical reagent grade in a 125 ml pack, it develops a deep purple colour with free amino acids on warming, which makes it the developing reagent in a paper chromatography kit for school biochemistry. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, with an MSDS in each pack.

What Is Ninhydrin Solution Used For?
In paper chromatography, students spot a mixture of amino acids, or a digested protein sample, on chromatography paper and run it in a solvent inside a closed jar. Once the paper is dry, it is sprayed or dipped in ninhydrin and gently warmed; purple spots appear where each amino acid has travelled, so students can measure distances and calculate Rf values. As a simple tube test, a few drops added to a sample and heated in a water bath show whether amino acids are present, which is handy for demonstrating that a protease has broken a protein down.
Ninhydrin reacts with the amino acids in skin, so it will leave purple stains on fingers; wear gloves and handle chromatograms by the edges. Spray only in a ventilated area, keep the bottle closed when not in use and check the MSDS for the solvent and any flammability warnings. Labs ordering from a chemistry consumables supplier in India usually buy it together with chromatography paper and jars.
Supplier
Ninhydrin solution is supplied by Jain Scientific Equipments Private Limited, trading as ScienceLab and located in Ambala, Haryana, India.

Frequently Asked Questions
What colour does Ninhydrin Sol (Test Of Amino Acids) give with amino acids?
Ninhydrin Sol (Test Of Amino Acids) gives a purple to blue-violet colour with most amino acids after warming. A few, such as proline, give a yellow colour instead, which students can note when identifying spots on a chromatogram.
Does Ninhydrin Sol (Test Of Amino Acids) detect whole proteins?
Ninhydrin Sol (Test Of Amino Acids) reacts mainly with free amino groups, so it is most useful for amino acids and digested protein samples. For intact proteins, the biuret test is the more suitable classroom test.
Is Ninhydrin Sol (Test Of Amino Acids) ready to spray on chromatograms?
Ninhydrin Sol (Test Of Amino Acids) is supplied as a solution in a 125 ml pack. Whether to use it directly or dilute it depends on your method, so follow your practical manual and the MSDS supplied with the pack.
Why does Ninhydrin Sol (Test Of Amino Acids) stain fingers purple?
Ninhydrin Sol (Test Of Amino Acids) reacts with the amino acids naturally present on skin, leaving purple marks that fade over a few days. Wearing gloves and handling chromatograms only by their edges prevents both stained fingers and stray spots.
What is the shelf life of Ninhydrin Sol (Test Of Amino Acids)?
The shelf life of Ninhydrin Sol (Test Of Amino Acids) 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 it tightly closed away from heat and light.
Who supplies Ninhydrin Sol (Test Of Amino Acids)?
Ninhydrin Sol (Test Of Amino Acids) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges and dealers in India and international markets, usually together with chromatography paper, jars and other biomolecule reagents.
Can Ninhydrin Sol (Test Of Amino Acids) be quoted with chromatography apparatus?
Yes. Send one list with Ninhydrin Sol (Test Of Amino Acids), code SCL404/0112, plus the chromatography paper, jars and any other items through the contact page, and a single combined quotation will be prepared.
