Freeze drying cattle blood typing reagents.
A system is described for freeze drying and storage of reagents (antisera) used in cattle blood typing tests. Reagents were freeze-dried in evacuated bottles at the desired dilution for rapid reconstitution to use in test procedures. Reagents not in current use were dried in bulk lots and stored in polyethylene film bags. All freeze drying procedures were performed with readily available commercial equipment. A computer program was developed to produce a current inventory of reagent supplies and projections of the number of samples which can be typed.
