In our lab we "amplified" the use of ATCC strains by culturing them for the
first time in a solid agar and then harvesting to a Microbank vial. Each
vial contains 25 beads, you can keep the bacteria viable for a long time
at -20 and for ever at -70. You roll each time you need a bead directly on
the agar, so from the original comercial loop you get 25 . Good look!
