The Influence of a Plasma Factor on the Erythrocyte Antibody-Antigen-Bromelin Reaction

Electron Microscopic Investigation of the Binding of Bromelin by Erythrocytes

“…which substantiates serologic observation of enhancement of serum on the reaction of bromelin by Pirofsky [14].…”

A New Diagnostic Test for Antiglobulin Positive (‘Auto‐Immune’) Haemolytic Anaemia*

“…This advantage, however, may lead to some confusion. Prior studies havc indicated that the bromelin-antibody-erythrocyte reaction is dependent on a serum or plasma factor (Pirofsky, 1960). When erythrocytes giving a positive bromelin test arc washcd three times in isotonic saline, and a bromelin test performed, consistently negative rcactioiis are obtained.…”
