Methylene Blue (Cellulose)
Methylene Blue (Cellulose) (Product Code: SCL455/0138) is a blue biological stain used to add contrast to plant cell walls, nuclei and cell outlines for observation under a compound microscope. It is listed for cellulose, meaning plant cell wall work, although students also meet it in cheek-cell and simple bacterial smears, and it comes as 500 ml of analytical reagent grade with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for school biology lab equipment lists.

What Is Methylene Blue Stain Used For?
In a typical practical, a thin plant peel or section is laid on a clean glass slide, a drop of methylene blue is added and left briefly, the excess is drained or blotted away, and a coverslip is lowered at an angle so that no air bubbles are trapped. The blue dye binds to acidic components of the cell, so walls and nuclei stand out against a pale background. Outside plant work, the same dye is familiar from cheek-cell smears in introductory cell biology and from simple staining of bacterial smears in microbiology.
A 500 ml stock is far more than one class uses in a session, so most labs decant a working quantity into a small dropper bottle and keep the main container tightly closed and out of direct sunlight. Methylene blue marks skin, clothing and bench surfaces easily, so gloves, a lab coat and a tray under the slides are sensible precautions. The MSDS supplied with the reagent covers storage, handling and disposal for secondary and senior-secondary practicals on cell structure.

Frequently Asked Questions
How much stain is in one container of Methylene Blue (Cellulose)?
Each container of Methylene Blue (Cellulose) holds 500 ml of analytical reagent grade stain. Because only a drop or two is used per slide, one container covers many practical sessions, although the exact number depends on class size and how the stain is dispensed.
What is the shelf life of Methylene Blue (Cellulose)?
Shelf life depends on the chemical, its grade and storage conditions, so we do not quote a fixed period for Methylene Blue (Cellulose). Ask us for the expiry date of the batch you are quoted, and keep the container tightly closed in a cool place away from direct light.
Is a safety data sheet provided with Methylene Blue (Cellulose)?
Yes. Methylene Blue (Cellulose) is supplied with an MSDS, which sets out safe handling, storage, first-aid and disposal information for the lab in-charge. Keep it with the laboratory's chemical records and share the key points with students before the practical.
Can Methylene Blue (Cellulose) be used for animal cells or bacteria?
Methylene blue is widely used in teaching labs for cheek-cell smears and simple bacterial staining as well as plant material. Methylene Blue (Cellulose) is listed for cellulose work, so if your protocol needs a particular strength, please confirm it with us before ordering.
Is Methylene Blue (Cellulose) supplied ready to use?
The listing for Methylene Blue (Cellulose) does not state the concentration or form of preparation. Please contact us through the contact page to confirm the form and strength of the current supply against your practical manual before ordering.
Who supplies Methylene Blue (Cellulose)?
Methylene Blue (Cellulose) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company quotes schools, colleges and distributors in India and international markets; include the product code SCL455/0138 and the quantity you need in your enquiry.
