The study covered material from patients with brain cancer (astrocytoma G-2). Cancer cells were homogenized, and heat-treated denaturation of cancer cells homogenate was performed. The solution containing heat-stable proteins was applied to a column filled with Sephadex. The results of the study showed that metallothioneins – heat-stable proteins – appear in the eluate in the same fractions as proteins obtained from a rabbit’s liver in the same experimental conditions. The presence of zinc ions was observed in the same fractions as metallothioneins, which indicates that zinc is a stable element in the structure of proteins.
