Not Telling
I am new here, so I hope I posted this in the right place. I am developing a protocol to extract DNA for positive identification of fungal conidia from tissue swab samples. I want to use lyticase or zymolase. My question is how do I determine the concentration of lyticase or zymolase to use? I am planning on pressing the swabs against the sides of an ep tube with maybe 750 to 1000 ul of the enzyme in solution then incubating for a while. I don't expect there to be a ton of conidia on the swabs; we just need to determine the presence of the fungi using PCR.
Thanks,
Jim
