Sporeworks' Syringe Tek v1.2
Overview:
With this method we are going to create a clean
and contaminant-free spore filled syringe. The
syringe will be filled with heated and sterilized
water and allowed to cool. The spores will then
be transferred from spore
print into the syringe solution using a cleaned
and sanitized shot glass. At the completion of
this Tek you will have created a spore solution
syringe ready for use in any microscopy application.
NOTE: These instructions
are most effective when performed in the most
sterile environment available. The preferred method
involves following the steps below while working
in a clean and sterile glovebox or in front of
a laminar flow hood. There are many simple methods
of glovebox construction; most are available on
the web at popular mycological
culture websites. If you do not wish to construct
a glovebox, or do not have one, the following
steps have been performed with success by working
on a thoroughly cleaned and sanitized countertop.
Liberal use of spray disinfectant and diluted
bleach solution is recommended for cleaning and
sanitizing the work area.
Materials needed:
Empty sterile syringes
Two quart (or larger) cooking pot
One bottle of 91% isopropyl alcohol
Several paper towels
A lighter or alcohol flame
A shot glass
Sterile spore print
Procedure One:
Making a sterile syringe
1. Fill your cooking pot halfway with tap
or distilled water (use distilled water if your
tap water contains higher levels of minerals and
chemicals).
2.
Boil the water in the pot on high for a minimum
of ten minutes, this should be adequate to sterilize
and cleans the water of all bacteria, viruses,
and mold spores.
3.
Take your empty syringe and fill it with the boiling
water. Allow it to sit for two minutes with the
hot water inside. (If your syringe was sterility
packaged, skip steps 4 and 5).
4.
Purge the hot water from the syringe into a sink,
not back into the saucepan.
5.
Repeat steps 3 and 4 two more times. Upon the
second time leave the hot water in the syringe.
6.
Place the syringe in a cool draft-free place,
preferable in a clean zip-lock bag
7.
Allow it to cool for several hours before proceeding
to Procedure Two.
Procedure Two: Transferring
print spores into syringe
1. First clean your work area. This may
involve wiping down all work surfaces with a diluted
bleach solution and spraying the area liberally
with a disinfectant such as Lysol.
2.
Place the following materials in your glovebox
or on the cleaned and sanatized working surface:
The shot glass, your cooled syringes, the bottle
of alcohol, a paper towel, your print (still in
zip-lock baggie) and the lighter or alcohol flame.
3.
Wash hands with antibacterial soap before proceeding
further.
4.
Fold the paper towel up into ¼ sections and soak
a corner of it with the alcohol.
5.
With the alcohol soaked towel wipe the interior
of the shot glass, essentially sterilizing the
surface you are about to use in the transfer.
Allow the shot glass to air dry, should only take
a few seconds.
6.
Remove the needle guard from your sterile syringe
and flame sterilize the needle. Then take your
alcohol soaked paper towel and wipe the needle
to further aid in the sterilization. Try to avoid
letting the needle touch any other surface unless
otherwise instructed to do so.
7.
NOTE: it is important
at this point to work as quickly as possible to
help combat the chances of contaminating molds
and bacteria falling into your work area and thereby
ruining your syringe.
8.
Remove the print from its storage baggie. Unfold
it to expose the spores. Lightly begin to scrape,
using the needle of the syringe, a section of
the print off into the shot glass. For a medium
sized print it is usually adequate to scrape off
a section no larger than 1/5 of the total print.
9.
You will have a small noticeable collection of
spores in the shot glass. Now expunge no more
than half of the water from the syringe into the
shot glass, lightly stirring the spores into the
solution.
10.
Suck the spore water solution into the syringe.
You may need to expunge some more water into the
shot glass and re-suck to help in capturing all
the spores into the syringe.
11.
Once you have the spore solution back into the
syringe you should notice that the water inside
has become slightly tinted and you may see small
clusters of spores floating in the solution. This
is good, you have completed the process.
12.
Sterilize the needle again with the alcohol soaked
paper towel, replace the needle guard and place
the syringe back into your clean zip-lock bag.
13.
Allow the syringe to sit for no less than 12 hours
before using in microscopy application or inoculation
for edible varieties. The older the print used,
the more "dehydrated" the spores will
become. For proper microscopy observation or germination,
the spores will need to be allowed to rehydrate.
