It's likely an aggregate of supercoiled DNA, the 300nm loops I think would still be way too small. And if you recently ate something especially with starches, you might be seeing a lot of alpha-amylase proteins! We did some similar things in my Biotechnology lab.

I am sure you can do fluorescence microscopy . You could use a DNA fluorochrome stain such as Acridine Orange to stain the DNA. Alternatives are natural DNA staining fluorochromes include Berberine (from Barberry - Berberis spp.), and extracts from Greater Celandine (Chelidonium majus) which is a common plant in many parts of the world, and Plume Poppy (German = Federmohn) (Macleaya sp). You don't specifically need UV for this fluorescence, because most of these stains can be excited with Blue light and emit a yellow gold color.
Sir you could use lens cleaner as protease to degrade proteins (histone) that binds up dna and see in micro scope of high resolution you may get a better view of dna
you should've used eye drops as they have cellulase and amylase and starch would be destroyed, more chances of actually seeing DNA. although i think the micrographs you got at the end, the little beads on string are actually DNA. you madman Oliver I love you you did it
Im learning a lot more with your videos than with my classes at the university. I've seen your gallery, it's fantastic, I use the pictures to compare what Im looking in the microscope. Your job is amazing
point of classes at university is to give you the background to allow you to get to these types of things on your own, designing and figuring things out. just watching and learning specific things is mostly only beneficial for a particular job or task. it can be more motivating because its more interesting, but it should motivate you to learn the class stuff.
Dishwashing solution. A non ironic surficant dissolves away the fatty acid in the cell membrane and lets the contents spill out. Great for disinfecting also
Most excellent spit sample microscopy analysis. Whether or not we could see dna is compensated by impressive discussion of observed micro forms and structures. Bravo!
Must admit the title and thumbmail got me it - "look at my DNA under the microscope" and the head of Microbehunter - I'm thinking, wrong website/hub. But no, it's educational, what a surprise.
You have the best channel on microscopy, but you need more videos about vintage microscopes, vintage (and modern) staining methods, and diy staining (there's something on the internet, but I only believe in your recipes 😉).
I don't have my microscope yet. It will be here Wednesday. But I still find y our videos fascinating. I had no idea one could isolate DNA like this. I guess I better start saving up for my very own Scanning Electron Microscope. :)
Hello, I’m currently a freshman starting veterinary medicine and I’ve been looking for information on how “far” a microscope can let us observe. My question is, and I would appreciate if you help me answer it, could one observe the DNA of an animal thru the microscope? Other than bacteria and cells, what else can a microscope let us observe? Please and thank you.
I had experienced and did many experiments in the high equipped lab while doing my post graduation in microbiology discipline... ! My researches included microbiology, biotechnology, biochemistry,cell biology and molecular biology... !
DNA reacts with diphenylamine based on the conversion of deoxyribose sugar in the DNA molecule (not in RNA), so when hydrolyzed at high temperature in an acidic environment to form hydroxylevulinyl aldehyde which reacts with diphenylamine to form a blue complex sustainable construction. So you can do this extra step to identify colored DNA when observed under a microscope and see :)
I know that the DNA, which is an acronym for De-oxy-ribo-Nucleic-Acid, is a double helix structure with some tiny steps and phosphate sugars on it but, I don't think I can actually see those things under my personal microscope. What is the name of the detergent you made use of? Is it Persil, Tide or Gain?? Or did you make use of any common detergent? I'll try this experiment once again and make sure I get the right viewing under the microscope. BTW, this video was amazing! Thanks for sharing.🎆🎆😁😁😊
Incredible video! Seeing any amount of DNA under a light microscope of all things is far better than nothing at all. Thank you for the tip. However, can you go more into detail about this procedure? Never heard of this before and not too sure about the materials, for example if it is better to use 99% isopropyl alcohol or something much lower like 70%. Many Thanks again!
I have used 96% (about) ethyl alcohol. It works better when the alcohol is ice cold, but I did not cool it and it also worked. The DNA participation with alcohol is standard procedure in molecular biology. The alcohol reduces the polarity of the water to the extent that DNA can not be dissolved anymore. Normally one would collect the DNA by centrifugation after the addition of alcohol.
It's an Olympus BX53 with Planfluorite objectives (4x 10x 20x 40x 100x oil) and Differential Interference Contrast (DIC), which is expensive but produces very nice images. You need a separate prism for each objective and they need to be fit in into a condenser with a rotating turret. I obtained several offers, all similar in the price range, some even more expensive.
How it possible to see a small molecule to under the compound microscope because the resolution is 0.3 micrometer and magnification power is 1500x while the size of DNA molecules is 0.6 manometer.
First of all how do u know this steps i mean did u learn it somewhere or read it in some text book ? How can i make sure that what u did now is real science ? Thank u
I’m a cosmetology teacher and I have thoroughly enjoyed this. I want to find a microscope with proper lenses and magnification to view hair at its cellular level. I’d also like to be able to view things like hair color’s molecular structure. Any ideas on which strengths I may need?
I still wonder if my science teachers were this amazing ..I would have choosen science for rest of my life... Though with no regrets ... Being a commerce graduate...I still carry my interest for science experiments. 😀
i've never done more than school microscopy, but i wondered if just putting like an piece of plant or insect on a glass was enough to see inside and since you said something with dish soap, that breaks the structure and makes the cells inside visible, is this the way to make the inside visible? or is the inside visible anyway? i've read thing about microscopic knife too...
Not only is the video cool, but the micrograph website is really cool! Could this be done with a cheap educational microscope? Like a normal 1000x compound scope? Keep in mind I know NOTHING about chemistry and little about DNA, but could this be mucus or something? It certainly acts like it, but I dont know.
hypothesis: those strings/nets could as well be microtubules, or even recombining cell wall proteins. i do not trust alcohol to preserve long dna chains and certainly not bleach. maybe we should try this experiment by centrifuge
Alcohol does preserve DNA, Alcohol precipitation is the standard method for DNA isolation. Beach was not added, its oxidizing ability would indeed destroy DNA.
You say looking at lood has no diagnostic value ! How is it that you see sichel cell ? Or how is it when you see an infection . Or let me go further how can you see if blood is infected ?
To check for infections, you do a PCR or an antibody test. There are only very few infectious diseases that can be diagnosed with microscopy. Malaria being one of them. Microscopy is simply not specific enough. If you have an infection in a wound, then you can of course isolate and see the bacteria, but then you already know that you have an infection....
It has to be done in a lab. However it is not intact. Once you remove the histones (proteins keeping DNA integrity) when you try to purify DNA, you end up with broken pieces of denatured DNA. However for lab purposes, even broken DNA is useful.
I was thinking to do this experiment 🔥😎 But when I told my father to bring some alcohol for me he was started to explaining me that how a man can get difficulties after taking alcohol and stuff😂😂😂😂 (I didn't tell him that why i am demanding for it)😂😂😂
I don't know man, You'll have to extrapolate on how dishsoap 'breaks open the cells' Also precipitation is the result of a chemical reaction of elements not the result of 'separating DNA from living tissue' Also, doesn't our mouth and entire digestive system literally always have various bacteria present?
Just tried it, ended up with a white/gray goo that I tried to spread 'under' my inverted microscope. Think I need to first alter my dna to get a third hand to hold everything in place while I look at it 😂
sir and one day I saw in my house that when i store water in a container for 3-4 days then i an see some white color floating on the water can you tell what is that
Can you suggest a home available stain that would be more specific to DNA that would be fairly non-toxic? Since DNA is acidic, maybe there could be a basic dye (I am thinking that Malachite Green available in the pet section of stores for Fish Ich, but know it is highly toxic). Aloha from Big Island! -Sid
that would be difficult to know with the steps he took. He used saliva; there are bacterial DNA mixed as well for sure. The only way to know if it comes from bacteria or him, is to amplify it and run the DNA code. However, his video is more about how to visualize DNA in a light microscope. The DNA is going to be mixed and from different sources for sure.
