β¦ Synopsis
A laboratory process for the isolation of type B acid phosphatase from human erythrocytes has been scaled up 80 times. The enzyme was purified 1300-fold by adsorption on calcium phosphate gel, ammonium sulfate precipitation, and gel filtration. The yield was 277,. Results for the type A enzyme are also presented.

A glycopeptide (called "senescence-factor glycopeptide", SF-G) has been isolated from a tryptic digest of human erythrocytes by specific adsorption and elution from immobilized peanut lectin. SF-G was detectable in old but not in young erythrocytes isolated from the same unit of blood. It is present
