Proteins and enzymes offered by Aniara (and produced by HYPHEN BioMed) are prepared with highly resolutive purification techniques. They offer a high purity grade, a high specific activity and an excellent stability.
Proteins are extracted from first grade biological material (human or bovine plasma, platelet concentrates), which is specifically selected for these preparations. The material is tested in order to offer the required viral safety. These products are presented in the freeze-dried form. Enzymes are then specifically activated and stabilized through well-controlled processes.
All these biochemicals are particularly useful for all research protocols, for quality control procedures and for developing specific functional assays.
Purified human proteins are extracted from non-activated citrated human plasma, which is only used for these preparations. Proteins are purified with non-denaturing methods, which allow keeping the structure and the biological activity of the native molecule. Usually proteins are lyophilised in presence of glycine, hepes and sodium chloride. Some preparations are lyophilized with excipients, which do not contain amino groups. This allows using directly the reconstituted products for covalent coupling. Each protein is packaged with its specification sheet, which includes an analysis certificate, indicating the protein content (Lowry method and absorbance at 280 nm) and the specific activity.
Viral safety: The material used for protein preparation is tested with registered methods and found negative for HIV (1 and 2) antibodies, HBs Ag and HVC antibodies. However, no assay may warrant the total absence of infectious agents. Any product of human origin must then be handled with all the required cautions, as being potentially infectious.
