Also a great gift for students, teachers, homeschool parents, and science Enthusiasts! Methylene blue (1% aqueous solution) Methylene Blue is a popular alkaline stain used to stain animal cells to make nuclei more visible. Methylene blue binds DNA which is very abundant in the nucleus. Cell stained by methylene blue will show the nucleus with deep blue color. It also helps make cells show up against their background, where their shape can help you determine what they are (their morphology). Methylene blue is also used by aquarium hobbyist for preventing fungal disease. Eosin Y (0.5% aqueous solution) Eosin Y Stain is a counterstain to Methylene Blue. It is most commonly used as an acidic red stain for highlighting red blood cells, cytoplasmic material, cell membranes, and extracellular structures in pink or red colors. In the hospital, Eosin's most important medical uses are H&E (haematoxylin and eosin) staining. H&E staining is one of the most commonly used techniques in histology. Tissue stained with haematoxylin and eosin shows cytoplasm stained pink-orange and nuclei stained darkly, either blue or purple. All solutions are for educational use only. Not for Food, Drug or Cosmetic Use. Keep Out of Reach of Children. ## Features - Methylene Blue (1% aqueous solution) - to stain cell nuclei blue and make their morphology more visible. - Eosin Y (0.5% aqueous solution) - a counterstain to Methylene Blue to stain cytoplasmic material and extracellular structures in red color. - Both in 1 oz amber boston round blass Bottle - w/Glass Dropper - easy to use and dispense onto a microscope slide.

I have tried to perform a blood smear -nothing works. Does anyone have an insight?** A: This product is a water based stain. Unfortunately it will tend to wash the blood off the slide unless you fix the blood smear with methanol before using the stains. Even then you will tend to have poor luck. This product is useful to stain cells for counting in a hemocytometer, but not so much for blood smears. I would suggest buying some methanol to fix the smears then using Wrights stain in methanol solution for staining. A cheap source of methanol is HEET gas line additive and water remover (yellow bottle) from your auto parts store. It is pure methanol. Fixing the smear simply means putting the slide in methanol for 30 seconds. **Q: Do you have to clean the slide with deionized water or do you just put the stain directly on the slide?** A: If the slide is new, wipe off dust, if there is any. If the slide has been used and has methylene blue on it, you may need to clear the stain with a bleach solution. Otherwise, wiping a used slide with alcohol may be good enough. **Q: Are they in powder form or solution? If in solution, are they water or alcohol-based?** A: Solution, water-based. **Q: Why can't this be supplemented? It is lab grade or lower quality?** A: What do you mean by supplemented? These work as well as lab grade. What are you staining? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Support Science Education *by T***N on October 19, 2019* The stain kit arrives well-packaged. Included in the kit are some basic accessories and a set of instructions for those who are just getting into the hobby.This kit was purchased for assessing the viability of yeast for brewing. Everything works exactly as expected.This kit differs from others in that the stains are stored in superior, light-resistant brown dropper bottles. Most of the other manufacturers choose to use clear/opaque packaging. Methylene Blue stain solution is degraded by exposure to light. The choice of packaging extends the life of the stain solutions by reducing exposure to ambient light. Keep stain solutions stored in a cool, dark place away from light when not in use (the shipping package works perfectly for this).Thanks Rs' Science ! ### ⭐⭐⭐⭐⭐ Works fairly well! *by C***K on December 25, 2020* I used these stains for fungal microscopy. They worked great. The insert was fairly informative, although I ended up looking up protocols online. Decent volume in amber glass bottles. Comes with the dropper in the cap. I wanted some basic stains because I was tired of not being able to find any at work! I'm glad I ordered these, although I probably should have considered a package with more stains. Now, most stain kits come with at least methylene blue, so there will be some extra if I end up taking that route. ### ⭐⭐⭐⭐⭐ Great kit, packaged nicely. *by K***G on October 20, 2020* These solutions worked exactly as expected. The nice extra touches were the seller including an absorbing table cover and plastic gloves for use while working w/ this highly-staining solution, as well as an informative (not boring) pamphlet on how the solutions work. ## Frequently Bought Together - Methylene Blue and Eosin Y Solutions - 30 ml (1 oz) in Amber Glass Dropper Bottles (for Microscopy, Ready to use) - AmScope BS-50P-100S-22 Pre-Cleaned Blank Ground Edge Glass Microscope Slides and 100pc Pre-Cleaned Square Glass Cover Slips Coverslips - Microscope Immersion Oil, Type A, 1/2 Oz (15 mL) in an Easy-to-Use Amber Glass Dropper Bottle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/38596162-methylene-blue-and-eosin-y-solutions-30-ml-1-oz](https://www.desertcart.kr/products/38596162-methylene-blue-and-eosin-y-solutions-30-ml-1-oz) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-11*
