<p>A chemically modified lymphokine having a group of R(-O-CH2CH2)n- (wherein R is a protective group for the terminal oxygen and n is an arbitrary positive integer) directly bound to at least one primary amino group of the molecule. It can be prepared by reacting lymphokine with an aldehyde of R(O-CH2CH2)n-1-O-CH2CHO (wherein R and n are as defined above) in the presence of a reducing agent, and is useful as medicine, etc.</p> |
