title: A method for the assay of ablastin in the serum of rats infected with Trypanosoma lewisi.
abstract: This paper describes a simple quantitative assay for albastin, a factor present in the serum from rats infected with Trypanosoma lewisi, which prevents the division of the parasite. The assay measures in vitro the inhibition of the incorporation of 3H-TdR into the DNA of T. lewisi in the presence of serum from infected animals. Utilising this method, one can measure the titre of albastin in a particular serum sample and the time and duration of its appearance in the circulation of infected rats.
