DON'T USE IODINE.
It kills the tissue...from my experience

I use iodine rubs over the tissue before biopsies for culture isolates. It kills off most contaminates and doesn't seem to stress the tissue out as much as H2O2 does as the mycelium recovers in agar sooner with these than with H2O2 dipped biopsies...

Hmph, probably just me. I used a 100% iodine solution though...

You shouldn't need to do anything but clean the surface if you're using that tek. In fact, skip all the cleaners and just peel off a strip of mycelium like a banana peel, and then stick the needle into the freshly exposed flesh. Iodine is fine for cleaning the outside of the tissue, but use it at no more than ten percent. RR

So, you iodine the surface of the mushroom, then you peel off that layer, and scalpel out a peice and put it on a hardened agar plate? For an LC, you'd scoop out fresh tissue and fill the bore of the needle a section of myc. right? How you get it out?

That's the method I follow although if I was doing a liquid culture I would take a needle and flame sterilize it and while red hot, draw in a few cc's of air through the super-heated air of the flame. (sterilized air)
I would then plunge the needle into the exposed tissue and twist while pulling up on the plunger ever so slightly. That will cut a plug into the syringe. Then just place it into the LC and depress the plunger to "shoot" it in to the liquid medium.
Repeat by beginning at the flame sterilization procedure again...

I've had lots of new success using providone-iodine (very hard to find pure iodine)
but, u can take providone, mix it with 3 times the amount of h2o2, and it will precipitate iodine crystals, that u can dilute with dh2o, and have pure iodine. LOL.
k,
my 2 cents.

that's fine, just take several plugs from a very (relatively) close area on the fruit and flame sterilize between every single extraction.
because a single fruit can still contains multiple sub-strain genetics you want your biopsies to be very densely packed.

well, there is strength in numbers, make sure to have at least several in case one or more of them do not grow out.

I got a piece from the cap that was 2 mm (about 1/16") long. Can I clone tissue from the cap?
i was wondering this also if you can clone from the cap or just the stem.. in RR's video he shows you cloning from both but those are wild edibles i dont know if cubensis would be any different.
SPOCK1- what did you end up wiping down the mushroom with before you took your core?

yes and yes. just take several plugs from a very close area to ensure both similar genetics between the samples (multiple genetics can exist in a single fruit so cloning this way is kind of tricky) and to ensure that you have at least one biopsy that proves viable and starts growing out in the liquid medium. two or three plugs are all you need per 250ml LC to inoculate it...one would be fine, but the risk of it not growing out is higher.

is it best to rip the cap in half and take a core from the tissue there or go right up through the gills?

that has already been discussed in the beginning of the thread... after washing the exterior of the fruit with iodine, peel back the skin of the cap and take the biopsy from that exposed, sterile flesh.

ah sorry myco i thought that was just in reference to taking a core from the stem.. i asked a question earlier that didnt get answered which was syringe size all i have is an 18 gauge will that work or should i go for something bigger???

yea, it's fine.. a couple plugs extracted as described above works fine. I'd have to double check the archives but I vaguely recall there being less chance of multiple genetics when samples are taken from the cap rather than the stem...
easier to discern in an agar plate than in a liquid culture though as you can observe the growth in a more 2-dimensional view...
