E&O supply freshly harvested aseptically collected Donor Horse Blood and Sheep Blood. These blood products are oxygenated and supplied in both Bottles and Bags for convenient asceptical addition to culture media. Plasma products can be fractionated after the addition of a range of anticoagulants: Citrate, Alsevers, Sodium Oxolate, Heparin and EDTA.

All donor animal blood products are harvested from Stress Free Animals with guaranteed PCV’s and free from any microbiological inhibitors. The most common use is for the manufacture of Blood Agar Plates. Dehydrated culture media (Columbia Agar) is added to deionised water and then sterilized at 121°C. The molten agar is then cooled to 42°C, fresh Horse Blood or Sheep Blood is then added at a 5% or 7% concentration before being poured into petridishes.

Môi trường nuôi cấy vi sinh Maximum Recovery Diluent (MRD)

Formulated to ISO 6887-1, Maximum Recovery Diluent (MRD) is a diluent designed to maintain organisms by protecting the cells from unnecessary physiological shock that may occur using other aqueous solutions. MRD is used extensively in food and environmental testing.
The low level of peptone provides a protective effect but does not allow for multiplication during the short residence time in the diluent, 45 minutes. The sodium chloride prevents osmotic shock as the sample is initially diluted.

This formulation combines the osmotic pressure of the physiological saline solution with the protective action of the peptone to obtain good recovery of stressed microorganisms.
The sodium chloride ensures isotonic conditions and the low concentration of peptone does not allow cellular growth in the short period (2-4 hours) of time required for the preparation of the dilution bank of the sample

Isotonic diluent for the maximal recovery of stressed microorganisms according to ISO standards.
