Human beta-endorphin-like immunoreactive substances (beta h-EI) in human cerebrospinal fluid (CSF) were determined radioimmunologically. The cross reactivity of the antibodies to human beta-endorphin (beta h-E) amounted to 40% for human beta-lipotropin (beta h-LPH) whilst it was less than 1% for leu
