The effect of sheep anti‐L and certain cattle S‐system reagents on active potassium transport in sheep and cattle red blood cells

Abstract

SummaryCertain anti‐sheep L antisera stimulated active potassium transport in cattle red cells. All cattle red cells tested (red cells from 21 Jersey cows) which had an internal K level of less than 70 mmol/1 were stimulated but those with more than 75 mmol/1 of K (red cells from 7 Jersey cows) were not stimulated. Cattle S‐system reagents and isoimmune cattle sera produced by injecting red cells of low‐potassium type into cows with cells of high‐potassium type failed to stimulate active potassium transport in either cattle or sheep red cells.
