While attempting to delineate the reason for the reported extreme variability of beta-endorphin-like immunoreactivity (beta-ir) in human plasma (eg., nondetectable to 1 ng/ml) by standard radioimmunoassay, we noted that a substantial portion of circulating beta-ir was associated with erythrocytes. That erythrocyte associated beta-ir is authentic beta… CONTINUE READING
