Catalog No.: 10 bio-500
Quantity: 500 ml
Minimum order 10 units
The product is collected from fetuses in an aseptic place, in selected slaughterhouses. The animals are inspected by the Federal Inspection Service of the Ministry of Agriculture (SIF), for export of organotherapy products to the European Economic Community (EEC).
The product is packaged and standardized in 4.5Lt gallons. Each gallon is visually inspected to verify its proper labeling and the integrity of the product and packaging.
Collection, handling, processing and storage are conducted in order to maintain the properties and qualities of the serum. Each batch is accompanied by a certificate containing all the data of the biochemical tests carried out on the sera.
The standard required by the market is less than 25 mg/dl.
Our average is 15 mg/dL.
They are collected aseptically, by cardiac or venous puncture.
End filter size:
All sera are filtered through three cellulose acetate membranes with a porosity of less than 0.22 m.

Examined for protein pattern characteristics on cellulose acetate tape and pH 8.6 barbital buffer.
Test in Cell Culture:
Sera are tested at concentrations of 5 to 30% in order to subculture 10 generations of subcultures.
The serum is inactivated at 56°C for thirty minutes. This specification is valid for inactivated sera.
