Carrier erythrocytes from cattle can be prepared from cells stored in a hypotonic, porous, dialyzed state.
Hypotonic dialysis of bovine erythrocytes to 160-180 mosmol/kg produces cells with metastable pores. Cells stored for 3 weeks in a hypotonic dialyzed state can be used to prepare carrier erythrocytes. Pores generated by nonlytic hypotonic conditions are initially greater than 40 A in radius but shrink to less than 20 A with storage beyond 1 week. A metastable pore allows for hemoglobin isolation from hypotonically dialyzed cells.
