Preparation

-       Dissolve 52 g of mixture A in 930 ml of MQ water in a closed container， Adjust the pH to PH7.2~7.6 using 1M NaOH or 1M HCl. 

-       Autoclave at 121°C for 15 minutes (Nitrogen blanket autoclave recommended [1][2]; if the condition does not allow, see [3]).

-       Add 2 ml of stock B and 70 ml of Stock D (or stock C if pursuit for better performance)  to the 930 ml solution and make up to 1000 ml at 50~55°C. Shake well and pour the agar plate aseptically while the liquid is still hot.

[1]     Inert gas blanketing, also known as nitrogen gas protection, is a safe and reliable method of preserving volatile or oxidatively sensitive substances.

[2]     A simple method of inert gas blanketing in the laboratory:

-   GL45-cap reagent bottles filled with the liquid to be treated are placed in an airtight PP autoclave bag - provided in the pack (the bag is best placed on top of a stainless steel tray or in a steel mesh basket)

-   Squeeze as much air out of the bag as possible, then introduce nitrogen into the bag using a flexible tube and seal the bag (by tying a knot at the neck of the bag or using a heat-resistant rubber band - provided in the pack) when it is inflated to about half its maximum volume.

-   Place the tray in a microwave oven to boil the liquid or in an autoclave chamber to sterilise.

-   Be aware of the risk of asphyxiation from high concentrations of nitrogen and ensure that the operation is carried out in a ventilated room.

[3]     If inert gas protection is not intended,

-   GL45-cap reagent bottles filled with the liquid to be treated are placed in an airtight PP autoclave bag - provided in the pack (the bag is best placed on top of a stainless steel tray or in a steel mesh basket).

-   Squeeze as much air out of the bag as possible, then seal the bag (by tying a knot at the neck of the bag or using a heat-resistant rubber band - provided in the pack) immediately.

-   Place the tray in a microwave oven to boil the liquid or in an autoclave chamber to sterilise.

Note:

It is strongly recommended to operate within a clean bench when preparing the solution & agar plate.

When ordering with the blood stock, this item will be packaged with 2.8kg of dry ice as standard for international shipping. For domestic shipping, it is packaged with a 1.3kg ice bag.

International buyers are suggested to purchase defibrinated sheep blood or horse blood locally as far as possible, unless it is difficult to do so, to avoid risks in customs clearance at the point of entry, which is common for importing animal blood products.
