The disadvantage of reusing Petri dishes is the increased ...
as the agar will set in its container before it can be poured. Obtain sterile petri dishes and pour enough to cover the entire surface area of the plate and at least half of its depth. Avoid overfilling the plates and preferably do not allow the agar to contact the top edge ...
Water bath set to appropriate temperature; Incubator at 37°C with 5% CO2 and high humidity; Centrifuge; Centrifuge tubes; Pre-labelled dishes. For MDCK cells, the splitting ratio should be 1:10. Adjust the splitting ratio for the cell type. For instance, primary cultures, immortalized...
The whale blows snot up in the air but the drone pushes air down to fly, so technically the snot should just be blown away. Also the collection petri dishes are on the top of the drone not on the bottom. So how does this work? We approach a whale from behind as it is moving ...

(grow them in a nutrient-rich solution) in a Petri dish in the laboratory. The stem cells divide several times and scientists divide the population into other dishes. After several months, there are millions of stem cells. If the cells continue to grow without differentiating, then the ...
Now, 137 years later, scientists have published the first ever randomized controlled trial testing Listerine's gonorrhea claim in the medical journal Sexually Transmitted Infections. The verdict: the bad-breath mouthwash does indeed kill gonorrhea bacteria, both in petri dishes and in people's ...
” He’s one of the kind of pioneering thinkers around epigenetics and such. But one of the things that he mentioned to me was, he’s working with cells in a petri dish, in order to change the cell, he doesn’t do anything to the cell itself, he changes the culture that it’s ...
