Hello,
I would like to hybridize a probe and an anti-probe (ssDNA oligonucleotides) in a reaction vessel. What would be the best buffer to use? and the temperature of annealing?
Thank you
Hello, I suspect that a molecule I am using is causing bacteria to experience osmotic shock. What chemical properties should I look for to compare this capability with those of other substances?...
