一般說明

MUP选择性补充剂含有冻干形式的莫匹罗星锂。莫匹罗星锂选择性抑制乳制品中典型乳酸菌的生长,例如乳酸杆菌乳球菌链球菌明串珠菌,而双歧杆菌可以不受抑制地生长。

應用

MUP选择性补充剂用作TOS-MUP琼脂制备的补充剂。适用于乳制品中双歧杆菌的计数(益生菌、酸奶、类似酸奶的产品,以及含有双歧杆菌的婴儿配方奶粉等干奶产品)。

Questions

1–2 of 2 Questions  
  1. What is the quantity of mupirocin per vial please? Does it require pre-dissolution in DMSO before use?

    1 answer
    1. The typical composition (per vial) is: Lithium mupirocin 25 mg.
      And the final concentration per liter is: Lithium mupirocin 50 mg (conforms with ISO 29981/IDF 220: 2010).

      The preparation is as follows:
      Add 25 ml of sterile, deionized water to the lyophilizate in the original vial and dissolve by carefully swirling. Add the solved supplement to the base culture medium that has been cooled to 48°C ± 1°C.

      Helpful?

  2. Hi! I have TOS agar in the glass tube about 18 ml. How do I put MUP supplement into 18 ml tube as the supplement is pallet and it's hard to weigh out?So If you could give me solution to make this supplement in solution, that would be great!

    1 answer
    1. The preparation instructions for the supplement state that 25 mL of sterile purified water should be added to the vial to dissolve. For usage, 5 mL of supplement solution is added to 95 mL of the agar base and then dispensed to tubes or plates. The 18 mL volume of agar base would require the addition of 947 µL of supplement solution.
